Abstract
A device for conveying fuel is disclosed, The device has a storage pot with a pot base from which a fuel conveying unit sucks in fuel; a drawing ejection pump is provided with a mixing channel with at least one section constructed on the storage pot, extending from the pot base, and going through the storage pot. The device is disadvantageous in that, an independent component is also needed for the housing of the drawing ejection pump and is necessarily in a sealing connection with the storage pot. According to the device in the invention, the mixing channel (12) is formed integrally at the storage pot (5) that is posed in inclined manner, preventing formation of a side concave seen from the section of the mixing channel (12) from the pot base (6) toward the internal side (16) in a pattern drawing direction.
Description
Technical field
The present invention relates to a kind of device that is used for transfer the fuel according to the type of independent claims.
Background technique
By DE 10060293A1 known a kind of device that is used for transfer the fuel, this device has: the storage tank at the bottom of having jar, feedway extracts fuel from this storage tank; A suction type jet pump, this suction type jet pump have one be configured at least section on this storage tank, from said jar end extension and lead to the hybrid channel this storage tank.The shortcoming that this device has is, also needs a member independently for the housing of suction type jet pump, and this member must be tightly connected with storage tank.
The invention advantage
In contrast; The device of characteristic with characteristic of independent claims of the present invention has following advantage; The hybrid channel is completely integrated in the storage tank; And manufacture cost is reduced, and its mode is that hybrid channel and storage tank are manufactured one and tilt to place, make the hybrid channel towards the section of inboard along the hybrid channel direction see that not form side recessed.Because do not form side in the inboard recessed, through make the simple withdrawing pattern of die casting mould become possibility by scheme of the present invention.
Through the measure of enumerating in the dependent claims, can be implemented in the favourable further configuration and the improvement of the device described in the independent claims.
According to a kind of favourable scheme, the hybrid channel is being widened on the direction of the port in storage tank.At this, the angle of the oblique position angle of widening part with the hybrid channel at least is consistent.That is to say that the hybrid channel tilts to place in this wise, makes the section towards the inboard of widening part on the withdrawing pattern direction, extend.
Description of drawings
Accompanying drawing illustrates the embodiment of a simplification of the present invention, in ensuing explanation, will further set forth.
Embodiment
Accompanying drawing illustrates a simplified cross-sectional view of device of the present invention with the cross section.
The device that is used for transfer the fuel is disposed in the fuel tank 1, and such as electric fuel pump fuel is flowed to internal-combustion engine 4 through pressure piping 3 from fuel tank 1 pressure by supply unit 2 with improving.
Diverging out from the pressure piping 3 of this device one drives pipeline 8, and this driving pipeline drives a suction type jet pump 9 and is used for initiatively filling storage tank 5.Certainly, drive pipeline 8 and also can or otherwise be supplied to fuel by a unshowned backflow portion of internal-combustion engine 4.Drive pipeline 8 and lead in the suction chamber 11 of suction type jet pump 9 through the jet exit 10 that for example narrows down, this jet exit can form a nozzle.On suction chamber 11, connect a hybrid channel 12, this hybrid channel 12 is arranged in the virtual extending portion of jet exit 10 in this wise, makes the fluid beam of being discharged by the jet exit that drives pipeline 8 10 arrive in the hybrid channel 12 through suction chamber 11 straight lines.The working principle of suction type jet pump 9 is fully known, does concise and to the point the elaboration at this: through drive pipeline 8 and jet exit 10 thereof drive stream by the beam shape be directed in the suction chamber 11.Fuel around the jet of driving pipeline 8 drives from suction chamber 11 inflow hybrid channels 12, makes a surveying flow be introduced in the storage tank 5 through hybrid channel 12 together.In suction chamber 11, form a negative pressure, this negative pressure makes fuel aspirate perforate 15 from fuel tank 1 through one of suction chamber 11 and continues to flow into suction chamber 11.Extend on the vertical bearing of trend of storage tank 5 hybrid channel 12, and form a riser culverts.Hybrid channel 12 is arranged on the inboard 16 of circumference of storage tank 5.
According to the present invention, hybrid channel 12 is configured in integratedly on the storage tank and tilts to place in this wise, and it is recessed to make the section towards fuel delivery unit 2 of hybrid channel 12 on withdrawing pattern direction 22, not form side.According to present embodiment, hybrid channel 12 has longitudinal axis 12.1, and this longitudinal axis is obliquely installed like this, makes the section towards fuel delivery unit 2 of hybrid channel 12 on withdrawing pattern direction 22, see not form side recessed.Oblique position draws like this, i.e. longitudinal axis 12.1 and be parallel between the vertical direction 18 that withdrawing pattern direction 22 extends and form a sharp angle.The section of the outside of hybrid channel 12 is configured in the peripheral wall 20 of storage tank 5 integratedly.Withdrawing pattern direction 22 is confirmed by the moving direction of making storage tank 5 employed die casting dies.Withdrawing pattern direction 22 can be perpendicular to 6 extensions at the bottom of the storage tank.
According to the embodiment of the present invention, the storage tank 5 that has integrated hybrid channel 12 can be cast through simple die casting mould.Hybrid channel 12 is completely integrated in the storage tank 5.At this, storage tank 5 has from the 6 withdrawing pattern directions 22 towards the opened end portions extension at the bottom of the jar.At this, hybrid channel 12 look up withdrawing pattern direction 22 sides towards inboard 16 section that not form side recessed.Die casting mould is extracted in 5 along withdrawing pattern direction 22 from storage tank.According to mode of execution of the present invention, on die casting mould, need not be used for the inside slide block of withdrawing pattern.In contrast, the section towards the outside of hybrid channel 12 looks up in withdrawing pattern side and forms a side recessed 19.
