Embodiment
Below with reference to Fig. 1 and Fig. 2, the solenoid valve 1 of the first preferred embodiment according to the present invention is described in detail.
As seen from Figure 1, described solenoid valve 1 comprise one can preassembled armature component 2 and a pole core 41, described pole core has the sleeve 41a as prolongation disposed thereon.Described armature component 2 comprises armature 4, valve element 3, return element 7 and pressure containing part 5.Described pressure containing part 5 abuts against on the pole core 41 being surrounded by coil 42, wherein between armature 4 and pole core 41, has the working clearance 51.In order to handle described solenoid valve 1, make valve element 3 along the direction of the medial axis X of solenoid valve towards pole core 41, move and by return element 7, again get back to initial position shown in Figure 1 when power-off.
As also as seen from Figure 1, described solenoid valve 1 also comprises valve body 10, and described valve body is constructed to two-piece type in the first embodiment.The valve body 10 of described two-piece type comprises inner member 11 and outer member 12.Described inner member 11 and outer member 12 by means of press fit liquid-tight interconnect.In described inner member 11, form through hole 15, on described through hole, be provided with valve seat 16.Described valve seat 16 is opened and is closed by the part area 3a extending longitudinally of valve element 3.Described outer member 12 comprises bottom section 21 and lateral side regions 22.Reference character 14 represents the input hole in valve body 10, and wherein, described input hole 14 is by providing by two holes, and one is located in outer member 12, and one is located in inner member 11.In order to manufacture through hole 15 produce through hole by means of spheroid 13 liquid-tight close.As also as seen from Figure 1, between inner member 11 and outer member 12, form valve chamber 17, after described valve chamber is arranged on through hole 15 on fluid flow direction.From valve chamber 17, extend outward four tap holes 18 coaxially with medial axis X, described tap hole is equidistantly along the periphery of valve body 10.This is shown in Figure 2, and described Fig. 2 is the sectional view along the cutting line II-II of Fig. 1.Here it should be noted that, in Fig. 1, at the cutting line of medial axis X left field, be selected as demonstrating input hole 14 and armature cannelure 4a.
As also as seen from Figure 1, in the outer member 12 that is configured to basin shape, be provided with centre gangway 20, the part area 3a of valve element 3 is through described centre gangway.At this, between passage 20 and part area 3a, gap is set, for guaranteeing the mobility of valve element 3.
When handling solenoid valve 1, described armature 4 is attracted towards the direction of pole core 41, thereby the working clearance 51 is reduced.Described valve element 3 lifts from valve seat 16 thus, thereby opens the connection between input hole 14 and valve chamber 17, and fluid flows in described valve chamber 17.The internal surface 21a of described outer member 12 is now used as deflection element, and makes the fluid of input turn to 180 ° to enter into four tap holes 18.Therefore, described fluid-phase is radially inputted by input hole 14 for medial axis X, in inner member 11, with 90 ° of directional steerings towards through hole 15, and by outer member 12, turns to 180 ° to enter into tap hole 18 subsequently.In order to close described solenoid valve, finish coil 42 to power, thereby the return element 7 that makes to be supported on pressure containing part 5 is returned to initial position shown in Figure 1 by valve element 3 again.By the valve body 10 of multi-part type, can save complicated cutting.Described outer member 10 can be used as that profiled member is manufactured and therefore cutting be only limited to inner member 11.In addition, also can realize valve body 10 fixing on the sleeve 41a of pole core 41 by means of compressing to connect.Because, as also as seen from Figure 1, the lateral side regions 22 of described outer member 12 is almost surrounded described inner member 11 completely, thus also can realize enough sealings between inner member 11 and outer member 12, thus there will not be the leakage from input hole 14 to valve chamber 17.In addition, can be by simple mode, the compression distance that can freely select that enters armature 4 by valve element 3 is determined the lift height of armature 4, and therefore fast and simply the deviation being caused by tolerance is compensated.
Because tap hole 18 is arranged on the outer surface of inner member 11, so can produce these tap holes with cutting way without difficulty, because must not produce in the prior art for another example, only there is the very deep hole of minor diameter (length in hole and the diameter ratio in hole are: about 5: 1), and only need for example mill out described tap hole.
Fig. 3 and Fig. 4 show the solenoid valve 1 of the second embodiment according to the present invention, and wherein, the identical parts of identical function are in other words used with reference character identical in the first embodiment and are described.As seen from Figure 3, embodiment is different from the first, and the second embodiment has the valve body 10 that is constructed to three-member type.Described valve body 10 comprises the outer member 12 of inner member 11 and two-piece type, and described outer member comprises sleeve 12a and baffling dish 8.Described baffling dish 8 is connected with sleeve 12a, and wherein, described sleeve 12a has step-like sleeve-shaped.At described sleeve 12a, on the end face of pole core 14, form recess 23.Described baffling dish 8 have radially outside around lug area 9, as seen from Figure 4, described lug area is arranged in recess 23.As seen from Figure 4, here, under assembling condition, between described outer member 12 and lug area 9, be not only provided with radial clearance 31 and be also provided with axial clearance 32.Described axial clearance 32 vertically X is directed and between the sleeve 41a and lug area 9 of pole core.Therefore,, in the valve body 10 of three-member type, can, using sleeve 12a and baffling dish 8 as profiled member that can low cost fabrication, particularly as deep-draw part, manufacture.
Therefore, according to the present invention, can provide the solenoid valve of the valve body with obvious simplification, although described valve body is constructed to multi-part type, but can reduce significantly manufacturing expense.
In addition can also enter by inner member 11, the lift of the compression distance electromagnetic valve for adjusting in outer member.
The radial and axial gap that is located at lug area 9 places of baffling dish 8 makes described baffling dish 8 can carry out the movement being caused by tolerance.In addition, can between the passage 20 in the part area of valve element 3 3a and baffling dish 8, narrow gap size be set here, thereby the radial deflection that valve element 3 is caused by tolerance prevents valve element 3, in opening 20, block and be difficult in other words pass through.
