Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting device for an electromagnetic valve, and more particularly to a mounting device for a solenoid valve used in a fuel system of a vehicle.

[0002]

2. Description of the Related Art With the automation and sophistication of control systems, valves for controlling the flow rate have been used in various industrial fields.
For example, in a fuel system of a vehicle, an electromagnetic valve utilizing an electromagnetic force (solenoid) is known. However, since the electromagnetic valve generates vibration during operation, it is necessary to consider vibration damping of the mounting portion.

As a specific example, in the fuel system of a vehicle, the temperature of the gasoline tank rises as the outside air temperature rises, and the evaporation of the fuel becomes active. Therefore, it is necessary to temporarily store the generated gas. Therefore, the fuel evaporative gas is adsorbed by the granular activated carbon in the evaporator canister, and the negative pressure in the engine intake is used to purge the fuel evaporative gas adsorbed by the activated carbon while the vehicle is running, so that the engine intake air is removed. Configure the fuel system so that it is drawn into the system. A solenoid valve is used to control the flow rate of the fuel vapor.

Referring to FIG. 7, a fuel evaporative emission control device 1 for controlling the flow rate of the fuel evaporative gas in the fuel system will be described. As shown in the figure, the fuel evaporative emission control device 1 is interposed between the fuel tank 2 and the surge tank 4 of the intake manifold 3. The fuel evaporative emission control device 1 includes a two-way check valve 5 connected to a fuel tank 2, an evaporator canister 7 having a canister (activated carbon) 6 filled therein,
The electromagnetic valve 8 is roughly configured. The solenoid valve 8 is
It is also called a canister purge VSV (canister purge vacuum switch valve) or a purge valve. Then, when the fuel vaporized gas G in the fuel tank 2 reaches a certain pressure, it opens the 2-way check valve 5 and is adsorbed by the canister 6 of the evaporator canister 7. The fuel evaporative gas G adsorbed to the canister 6 is sucked by the negative pressure generated in the intake manifold 3 when the solenoid valve 8 controlled by the computer 10 opens while the internal combustion engine 9 is rotating, and the atmosphere of the evaporator canister 7 is absorbed. Through the solenoid valve 8 together with the air flowing in from the inlet 11,
It is sucked into the intake manifold 3 of the internal combustion engine 9 and burned in the cylinder together with the air-fuel mixture. However, the electromagnetic valve 8 is closed when the internal combustion engine 9 is stopped. On the contrary, when the inside of the fuel tank 2 reaches a certain negative pressure, the two-way check valve 5 is opened, air is sucked from the evaporator canister 7, and the pressure inside the fuel tank 2 is kept constant. In this way, the fuel system of the vehicle is connected to the intake system of the engine while controlling the fuel evaporative emission using the solenoid valve 8 so that the fuel evaporative emission evaporating from the fuel tank 2 or the like does not hinder the operating conditions of the engine. It is inhaled and burned.

In FIG. 7, reference numeral 14 indicates a pipe line for connecting the evaporator canister 7 and the solenoid valve 8, and reference numeral 15 indicates a pipe for connecting the solenoid valve 8 and the surge tank 4 provided in the intake manifold 3. Showing the road. The electromagnetic valves 8 are connected to the purge pipes of the fuel-evaporated-gas emission suppressing device 1 of the vehicle engine by these conduits 14 and 15. Further, reference numeral 17 indicates an air cleaner.

A side view, a front view and a plan view of the solenoid valve 8 according to the prior art shown in FIG. 7 are shown in FIGS. 8, 9 and 1, respectively.
It shows in 0. The reference numerals 8a and 8b indicate pipes for flow rate control, and the reference numeral 8c indicates a terminal (connector). That is, the solenoid valve 8 is connected via the conduits 8a and 8b as shown in FIG.
Communicating with the conduits 14 and 15 shown in FIG.
It is connected to the computer (control device) 10 shown in FIG. Further, as inferred from FIG. 7, the solenoid valve 8
Since the air cleaner 17 and the air cleaner 17 are arranged adjacent to each other, the solenoid valve 8 may be mounted on the air cleaner 17. In this case, as shown in FIG. 8, the solenoid valve 8 has a mounting hole 8e on the body.
A mounting bracket 8d having a mounting hole 8e
Is positioned and fixed to the air cleaner 17, which is the object to be fixed. However, since the solenoid valve 8 is driven by using an electromagnetic force (solenoid), the solenoid valve 8 is internally provided with a mechanism operated by magnetic force, and therefore the solenoid valve 8 itself generates vibration.
For this reason, when the solenoid valve 8 is not properly attached due to its structure, the solenoid valve 8 itself produces an unpleasant operating noise,
Alternatively, a component (not shown) to which the solenoid valve 8 is attached may be vibrated to make the driver uncomfortable.

Therefore, various measures have been conventionally taken to reduce the vibration generated from the solenoid valve 8. For example, rubber is burned on the valve seat that causes the valve body to open and close inside the solenoid valve 8, or the elastic characteristics of the valve seat are changed. However, in this case, the durability of the solenoid valve 8 may be lowered, and the cost is increased because an originally unnecessary member is used. Further, the electromagnetic valve 8 is attached directly to the engine of the vehicle to reduce the vibration propagation characteristic to the vehicle body. However, in this case, the electromagnetic valve 8 is required to have high vibration isolation, which causes a cost increase. Further, in consideration of durability of the solenoid valve 8, when the solenoid valve 8 is attached to the vehicle body side, rubber floating is applied to reduce the vibration propagation characteristic. However, in this case, since the solenoid valve 8 is required to simultaneously prevent rotation, perform positioning, and stop rotation for inserting the connector, two or more attachment points are required, which causes a cost increase.

Further, as the prior art relating to the mounting device of the solenoid valve, there are JP-A-2000-73882 and JP-A-1.
JP-A 1-210573 and JP-A-10-266923.
There is one disclosed in the publication. Japanese Patent Laid-Open No. 2000-738
The one disclosed in Japanese Patent Publication No. 82 relates to an evaporated fuel piping structure for a vehicle engine, which shortens the piping path, ensures sufficient clearance with other parts, and further reduces the amount of deflection of the purge pipe member. The feature is that it is possible to do. The one disclosed in Japanese Patent Laid-Open No. 11-210573 relates to the intake structure of an internal combustion engine, which eliminates layout restrictions, favorably distributes gas to each cylinder, improves development efficiency, and looks good. It is characterized by making it possible to eliminate paint defects. The one disclosed in Japanese Patent Laid-Open No. 10-266923 relates to an electromagnetic valve, and it is possible to perform a constant flow rate adjustment by forming a throttle passage having a constant inner diameter in the middle of the outflow passage. It is characterized by that.

[0009]

As described above, although there are a plurality of prior arts relating to the solenoid valve, however, it is economical and has a vibration-proof property that reduces the operating noise of the solenoid valve and improves the workability of assembling. What provides a mounting structure of a solenoid valve having excellent assembling property is not generally known.
The present invention has been made in view of the above points, and an object of the present invention is to provide a mounting device for a solenoid valve that is economical and that is excellent in vibration isolation and assembly.

[0010]

As a means for solving the above-mentioned problems, the present invention, in the invention described in claim 1, has an inflow conduit and an outflow conduit at one longitudinal end of a cylindrical case. A solenoid valve mounting device provided with a valve body that is formed and provided to control an amount of flow between the inflow conduit and the outflow conduit in an axial direction inside the cylindrical case. Is a floating bracket supported by an object to be fixed via an elastic member on the outer peripheral portion of the tubular case, and at least one of the hoses connected to the inflow conduit and the outflow conduit is It is characterized in that the vicinity of the connecting portion of the hose is fixed to the fixed object. With this configuration, in the conventional solenoid valve including the valve element that operates in the axial direction, the vibration during operation was easily transmitted from the mounting portion to the fixed object, but the solenoid valve was extended to the cylindrical case. The object to be fixed is floatingly supported via a fixing bracket and an elastic member, and at least one of the hoses connected to the inflow conduit and the outflow conduit is fixed to the object to be fixed in the vicinity of the connection part. Thus, it is possible to support floating at two places, and it is possible to block the vibration transmitted from the solenoid valve to the fixed object with a simple and low-cost structure without adding another vibration isolating member.

Next, in the invention described in claim 2, in the invention described in claim 1, the solenoid valve is provided with a connector for electrical connection at the other end of the cylindrical case, and the inflow pipe is provided. Among the passages and the outflow pipes, the interval between the pipe on the side close to the connector and the connector is L, and a mounting hole for the fixing bracket is provided at a position within a distance of L / 3 from the connector. It is characterized by In this configuration, since the mounting position of the fixing bracket is set within the distance from the connector to L / 3, when the mating connector is inserted into the connector of the solenoid valve, the mounting hole of the bracket is fixed on the hose side. Since the solenoid valve is prevented from rotating in cooperation with the parts, it is possible to improve the workability of assembling without the need to add another rotation preventing component.

Further, in the invention described in claim 3, in the invention described in claim 1 or 2, the solenoid valve is connected to a purge pipe of a fuel evaporative emission control device of a vehicle engine, and The solenoid valve fixing bracket and the hose are fixed to the air cleaner. With this configuration, vibration transmitted to the vehicle body from the solenoid valve used for the fuel vapor emission control device for the vehicle engine is reduced, and the solenoid valve is fixed to the air cleaner arranged close to the engine, so that the module can be assembled. It is possible to improve productivity.

The solenoid valve mounting device according to the present invention is basically constructed as described above. However, if it is a valve that generates vibration by itself and has a pipe such as a hose, it is a fuel for vehicles in particular. It is possible to apply not only the solenoid valve of the system but also the mounting device described above.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will now be described with reference to the accompanying drawings, in particular, with regard to a solenoid valve used in a fuel evaporative emission control device for a vehicle fuel system shown in FIG. This will be described in detail with reference to FIG.

FIG. 1 is a diagram showing a mounting structure of a solenoid valve 20 according to an embodiment of the present invention. In order to clarify the comparison with the prior art, the solenoid valve according to the prior art is shown by reference numeral 8 in FIGS. 7 to 10, whereas in FIGS. 1 to 6, the embodiment of the present invention is shown. Such a solenoid valve is indicated by reference numeral 20.

As described in the prior art, the solenoid valve 20
Since the structure itself generates vibration, the mounting structure requires anti-vibration properties. Therefore, as shown in FIG. 1, the electromagnetic valve 20 is usually attached to a larger fixed object 30 to damp the vibration. On the other hand, the electromagnetic valve 20 is often arranged adjacent to the air cleaner 17 in the vehicle (see FIG. 7), and therefore the air cleaner 1 is used as the fixed object 30.
Select 7. This is because by fixing the solenoid valve 20 to the air cleaner 17 arranged close to the engine, the module can be assembled and the productivity can be improved.
Therefore, the air cleaner 17 will be described below as the fixed object 30. However, the solenoid valve 20 according to the embodiment of the present invention may be attached to a member other than the air cleaner 17, and may be attached to a device other than the fuel evaporative emission control device 1 (see FIG. 7) of the fuel system of the vehicle. It should be appreciated that they may also be used.

Here, the internal structure of the solenoid valve 20 will be briefly described with reference to FIG. Normally, the solenoid valve 20 is provided with a conduit 2 at a base portion 40 at one end in the longitudinal direction of the tubular case 25.
1, 22 are formed and provided, and a valve body 48 and a valve seat 49 are provided in the axial direction inside the base portion 40 to control the flow rate between the pipe lines 21 and 22. The valve body 48 is operated by an electromagnetic coil 45 housed in the casing body 44. Inside the casing main body 44 sandwiched between the cover plate 26 and the under plate 47, a center post 41 extending in the axial direction is formed with the O-ring 42 sandwiched therebetween. A terminal (connector) 23 is provided at an end portion in the longitudinal direction of the tubular case 25 on the side opposite to the base portion 40, and the internal terminal pin 4 is provided.
A mating connector (not shown) is attached via 3, and a control current sent from an external control device (see reference numeral 10 in FIG. 7) is supplied to the electromagnetic coil 45. Therefore, both ends of the electromagnetic coil 45 are connected to the terminal pins 43 protruding outside the casing body 44. Therefore, by controlling the energization of the electromagnetic coil 45, the valve body 48 is moved to the valve seat 49.
It becomes possible to take a seat on and away from. That is, when the control current from the control device is not supplied to the electromagnetic coil 45, the valve body 48 is seated on the valve seat 49 by the elastic member 46 and closed, so that the flow of the conduits 21 and 22 is prevented. Be cut off. Then, when a control current is supplied from the control device to the electromagnetic coil 45 and the electromagnetic coil 45 is excited, the valve body 48 is separated from the valve seat 49 against the biasing force of the elastic member 46 to open the valve. And then flows through the pipelines 21 and 22. Due to this structure,
The solenoid valve 20 itself generates vibration.

Next, the air cleaner 17 for mounting the solenoid valve 20 will be described with reference to FIG. 1 again. Usually, the housing 30 of the air cleaner 17 is formed by engaging a first housing portion (cover) 31 and a second housing portion (body) 32. This is for facilitating inspection, replacement, etc. of the intake air filtering element (not shown) housed inside the air cleaner 17. Therefore, as shown in FIG. 1, the cover 31 engages with the main body 32 by using the fixing tool 34 on the end 33 side. In addition, this fixture 34 is a cover 3
It suffices to have a function of detachably assembling 1 and the main body 32, and the shape and the number thereof are arbitrary. Further, a plurality of mounting brackets 35 are formed on the main body 32 in order to equip the housing 30 at a fixed position in the vehicle. And the main body 3
A hose (not shown) for taking in intake air is provided on two sides to take in the intake air into the housing 30, the intake air is filtered by the above-mentioned element (not shown), and the cover 3
A hose (not shown) for discharging purified air is connected to the mounting port 31a on the housing 1, and a filtered flow is supplied from the hose to the housing 30.
Discharge to the outside.

Next, with reference to FIGS. 1 and 3, the overall structure of the mounting device for fixing the solenoid valve 20 on the air cleaner 17 according to the embodiment of the present invention will be described. Incidentally, FIG.
FIG. 2 is an enlarged view showing the solenoid valve 20 shown in FIG. 1.
As shown in FIG. 3, the solenoid valve 20 is provided by forming pipe lines 21 and 22 at the longitudinal end of a cylindrical case 25, and hoses 18 and 19 are attached to the respective pipe lines. The hoses 18 and 1
Reference numeral 9 corresponds to the pipelines 14 and 15 that constitute the purge piping of the fuel-evaporated-gas emission suppressing device 1 for the vehicle engine shown in FIG. 7. Of these conduits 21 and 22, one corresponds to the inflow conduit and the other corresponds to the outflow conduit. Hereinafter, for the sake of explanation, the pipeline 2
Let 1 be an inflow line and line 22 be an outflow line. In the embodiment according to the present invention, the solenoid valve 2 is attached to the air cleaner 17.
In order to mount 0, fixing parts 36 and 37 (see FIG. 1) are provided on the mounting surface 39 of the air cleaner 17. Then, the electromagnetic valve 20 is provided with a fixing bracket 24 (see FIG. 3), and as shown in FIG. 1, the bracket 24 is floatingly supported by the fixing portion 36 via the elastic member 38 c, and the fixing portion 37 is provided. On the other hand, one of the hoses 18 and 19 is clamped to form an attachment device. Specifically, as shown in FIG.
8a, spacer 38b, elastic member 38c, and washer 3
This is performed using the floating support member 38 composed of 8d. The elastic member 38c is preferably a grommet.
Further, the fixing portion 37 that holds the hose is preferably a clamp. The mounting device according to the embodiment of the present invention includes these hoses 18 or 19, the fixing bracket 24, the fixing members 36 and 37, and the floating support member 38.

In this way, the mounting position of the solenoid valve 20 is set to one point of the mounting hole 28 (see FIG. 3) of the bracket 24,
However, by inserting the piping hose 18 or 19 into the fixing portion 37 arranged on the air cleaner 17, the solenoid valve 2
Stop around 0. In this case, since the solenoid valve 20 can be positioned by the fixing portion 37 during assembly, an assembly jig or the like is unnecessary. Therefore, in the embodiment of the present invention, by utilizing the existing hose 18 or 19, the solenoid valve 2
No. 0 mounting structure is simplified and the vibration damping effect is improved. Further, when using the floating support member 38 to reduce the vibration propagation characteristics of the solenoid valve 20, unlike the prior art, it is possible to omit rotation prevention, positioning, and further rotation stop for inserting the connector. This is because the hose 18 or 19 also has these functions.

Next, each of the fixing bracket 24, the elastic member 38c, and the fixing members 36 and 37 according to the embodiment of the present invention will be described. Further, a side view, a front view and a plan view of the solenoid valve 20 shown in FIGS.
And shown in FIG. First, the fixing bracket 24 according to the embodiment of the present invention will be described. As can be seen from FIGS. 4 and 5, the conduits 21, 22 and the connector 23 are aligned to minimize the spatial configuration of the solenoid valve 20. Then, as understood from FIG. 4, the fixing bracket 24 is fixed to the side surface of the solenoid valve 20 having a relatively wide mounting surface. Preferably, the bracket 24 is provided orthogonal to the longitudinal direction of the body 25 of the solenoid valve. However, the method of attaching the bracket 24 and the solenoid valve 20 is arbitrary, and the bracket 24 and the solenoid valve 20 may be detachably assembled.
Further, as shown in FIG. 6, the bracket 24 is extended from the main body 25 so that the solenoid valve 20 is attached to the floating support member 38.
(See Fig. 1). A mounting hole 28 is formed on the end portion side of the fixing bracket 24 so that the bracket 24
Is fixed to the fixed object 17. In the embodiment shown in FIG. 4, the mounting hole 28 is formed in a substantially circular shape, and the side portion 27 of the mounting hole 28 is cut open to improve the assembling property of the bracket 24. However, the side portion 27 of the mounting hole 28 need not always be cut open, and the side portion 27 to be cut open.
The shape and the direction of are arbitrary.

Next, the elastic member 38c according to the embodiment of the present invention and the fixture 3 functioning as a pair with the elastic member 38c.
6 will be described. The elastic member 38c preferably determines the external shape based on the shape of the mounting hole 28 (see FIG. 4). Specifically, the shape of the elastic member 38c is determined so that the vibration propagating from the electromagnetic valve 20 through the mounting hole 28 is evenly propagated to the surroundings. However, the elastic member 38c
The shape of is not always limited to the substantially cylindrical shape as shown in FIG. Further, as shown in FIG. 1, the elastic member 38c has a spacer 38b inserted therein, and the spacer 38b is inserted from the spacer 38b to the fixture 36 via the washer 38d.
It is fixed by 8a. The fixture 36 is provided on the floating support member 3 so as to support the solenoid valve 20 in a floating manner.
8 (38a, 38b, 38c and 38d) are positioned and fixed.

Further, the fixture 37 according to the embodiment of the present invention will be described. As mentioned above, this fixture 37 is preferably a clamp. However, it should be understood that the shape of the clamp 37 is not limited to the shape shown in FIG. 1 or FIG. 3, and in particular, it is sufficient if it has a function of holding the hose 18 or 19. For example, it is optional to configure the clamp 37 (not shown) so as to hold both the hoses 18 and 19. Further, in the form shown in FIG. 3, the clamp 37 offsets and holds the hose 18 from two points, but this offset interval is determined according to the embodiment.

Next, referring again to FIG. 4, a further preferred embodiment of the present invention will be described. As shown in FIG. 4, in a further preferred embodiment of the present invention, the solenoid valve 20 includes an inflow conduit 21 and an outflow conduit 22.
Outflow pipe 22 on the side close to the connector 23 for electrical connection
The distance between the center of the connector 23 and the center of the connector 23 is L, and the mounting hole 28 is provided so that the center of the mounting hole 28 of the fixing bracket 24 is located at a position A within a distance L / 3 from the center of the connector 23. . Therefore, when the distance between the center of the connector 23 and the center of the mounting hole 28 is D, the size of D is always smaller than the size of L / 3. This point becomes clearer by comparison with the conventional technique shown in FIG. That is, in the solenoid valve 8 according to the conventional technique, the mounting hole 8e of the fixing bracket 24 is generally arranged at the position B near the center of the main body. In this case, the center of the connector 8c and the mounting hole 8
If the distance from the center of e is D ', the size of D'is L /
It is close to the size of 2. In the embodiment of the present invention, as compared with the conventional technique, the mounting hole 28 is arranged closer to the connector 23 side, and the hose 18 or 19 is used to control the solenoid valve 20.
Position and fix. In this way, when inserting the mating connector (not shown) into the connector 23 of the solenoid valve 20,
Since the mounting hole 28 of the bracket 24 cooperates with the fixing portion 37 on the hose 18 or 19 side to prevent rotation of the solenoid valve 20, it is not necessary to add a rotation stopping component (not shown) to the assembly workability. It can be improved, and it becomes possible to provide sufficient holding force when the mating connector is inserted.

As described above, the solenoid valve 20 shown in FIGS. 1 to 6 is connected to the purge pipe (see reference numerals 14 and 15 in FIG. 7) of the fuel-evaporative emission control device 1 for a vehicle engine, and By fixing the fixing bracket 24 of the solenoid valve 20 and the hose 18 or 19 to the air cleaner 17, as compared with the solenoid valve 8 according to the related art shown in FIGS. It was confirmed from the vibration transmission measurement that it becomes possible to provide a mounting device for the solenoid valve 20 having excellent mounting properties.

[0026]

Since the present invention is a mounting device for an electromagnetic valve constructed as described above, according to the invention described in claim 1, a solenoid valve having a valve element that operates in the axial direction has hitherto been used. In contrast to the fact that the vibration during operation was easily transmitted from the mounting portion to the fixed object, the electromagnetic valve is supported in a floating manner on the fixed object via the fixing bracket extending in the cylindrical case and the elastic member. By fixing the vicinity of the connecting portion of at least one of the hoses connected to the inflow conduit and the outflow conduit to the object to be fixed, it is possible to perform floating support at two locations, and another vibration damping member. It is possible to block the vibration transmitted from the solenoid valve to the fixed object with a simple and low-cost structure without adding the.

According to the invention described in claim 2, in addition to the effect of the invention described in claim 1, the mounting position of the conventional fixing bracket is set to a position within a distance of L / 3 from the connector. As a result, when inserting the mating connector into the connector of the solenoid valve, the bracket mounting hole cooperates with the fixing part on the hose side to prevent rotation of the solenoid valve, so there is no need to add another rotation prevention component. Assembling workability can be improved.

According to the invention described in claim 3, in addition to the effect of the invention described in claim 1 or 2, the electromagnetic valve used in the fuel-evaporative emission control device for a vehicle engine is transmitted to the vehicle body. Vibration can be reduced, and by fixing the solenoid valve to the air cleaner arranged close to the engine, the module can be assembled and the productivity can be improved.
