The shortcoming that this device has is, also needs a member independently for the housing of drawing-in type jet pump, and it must be tightly connected with storage tank. According to the present invention, hybrid channel is completely integrated in storage tank, and therefore manufacturing cost is reduced. According to the present invention, this hybrid channel (12) is configured in the upper and slant setting like this of this storage tank (5) integratedly, makes the section from (6) at the bottom of described tank towards inner side (16) of this hybrid channel (12) not form side in withdrawing pattern direction (22) recessed.
Description
Technical field
The present invention relates to a kind of device for delivery of fuel.
Background technology
By DE10060293A1 known a kind of device for delivery of fuel, this device has:A storage tank having at the bottom of tank, conveying device extracts fuel from this storage tank; A drawing-in type spraysPump, this drawing-in type jet pump have one be configured at least section on this storage tank, from described tankThat extension is played at the end and lead to the hybrid channel in this storage tank. The shortcoming that this device has is, for taking outThe housing of suction jet pump also needs a member independently, and this member must be tightly connected with storage tank.
Summary of the invention
In contrast, the present invention proposes a kind of device for delivery of fuel, has:
One has the storage tank at the bottom of tank, and supply unit extracts fuel from this storage tank,
One drawing-in type jet pump, this drawing-in type jet pump has one and is configured in this storage at least sectionOn tank, from the bottom of this tank extension and pass into the hybrid channel this storage tank, wherein:
This hybrid channel is configured on this storage tank and such slant setting integratedly, makes this mixingThe section towards inner side of passage looks up in withdrawing pattern side, and not form side recessed.
The device with the feature of such scheme of the present invention has the following advantages, and hybrid channel is completely integrated inIn storage tank, and manufacturing cost is reduced, and its mode is that hybrid channel and storage tank are manufacturedOne slant setting, make the section towards inner side of hybrid channel see not shape along hybrid channel directionBecome side recessed. Owing to not forming in inner side, side is recessed, by make die casting by the solution of the present inventionSimple withdrawing pattern becomes possibility.
By the measure enumerating below, can realize having according to device of the present invention as described aboveFurther configuration and the improvement of profit.
According to a kind of favourable scheme, hybrid channel is expanded in the direction of the port towards in storage tankWide. At this, the angle of obliquity is at least consistent with the angle of widening part of hybrid channel. AlsoBe to say hybrid channel slant setting in this wise, make the section towards inner side of widening part perpendicular to tankThe end or extend in withdrawing pattern direction.
According to a kind of favourable scheme, widening portion cyclotomy taper ground forms.
According to a kind of favourable scheme, described hybrid channel has a relatively described withdrawing pattern direction and tilts to establishThe longitudinal axis of putting.
According to a kind of favourable scheme, described storage tank is compression casting.
According to a kind of favourable scheme, the section towards outside of described hybrid channel is in described withdrawing pattern sideLooking up, it is recessed to have side.
Brief description of the drawings
Accompanying drawing illustrates the embodiment of a simplification of the present invention, in ensuing explanation, will further explainState.
Detailed description of the invention
Accompanying drawing illustrates a simplified cross-sectional view of device of the present invention with cross section.
Be disposed in fuel tank 1 for delivery of the device of fuel, and by supply unit 2 such as electricityMoving petrolift improves fuel to flow to internal combustion engine 4 by pressure piping 3 from fuel tank 1 pressure.
Supply unit 2 is arranged in one with in 6 storage tank 5 at the bottom of tank, and it is that supply unit 2 stores footEnough fuel, like this at fuel tank 1 during in low oil level and acceleration, braking, negotiation of bends and/Or also can be drawn onto fuel when ramp driving.
From the pressure piping 3 of this device driving pipeline 8 that diverges out, this driving pipeline drives a drawing-in typeJet pump 9 is for initiatively filling storage tank 5. Certainly, driving pipeline 8 also can be by of internal combustion engine 4Unshowned backflow portion or be otherwise supplied to fuel. Drive pipeline 8 for example to narrow by oneJet exit 10 leads in the suction chamber 11 of drawing-in type jet pump 9, and this jet exit can form oneNozzle. On suction chamber 11, connect a hybrid channel 12, this hybrid channel 12 is arranged in and penetrates in this wiseIn the virtual extension of flow export 10, make by the fluid that drives the jet exit 10 of pipeline 8 to dischargeBeam arrives in hybrid channel 12 by suction chamber 11 straight lines. The operation principle of drawing-in type jet pump 9Fully known, do concise and to the point elaboration at this: by driving pipeline 8 and jet exit 10 thereof to drive streamBy beam shape be directed in suction chamber 11. Drive the jet of pipeline 8 drive fuel around together fromSuction chamber 11 flows in hybrid channel 12, makes a conveying stream be introduced into storage by hybrid channel 12In tank 5. In interior formation one negative pressure of suction chamber 11, this negative pressure makes fuel from fuel tank 1 process suctionOne suction perforate 15 of chamber 11 continues to flow into suction chamber 11. Prolong the vertical of storage tank 5 hybrid channel 12Stretch in direction and extend, and form a riser culverts. Hybrid channel 12 is arranged on the circumference of storage tank 5On inner side 16.
According to the present invention, hybrid channel 12 is configured on storage tank and slant setting in this wise integratedly,Make the section towards fuel delivery unit 2 of hybrid channel 12 not form side in withdrawing pattern direction 22Recessed. According to the present embodiment, hybrid channel 12 has longitudinal axis 12.1, and this longitudinal axis is obliquely installed like this,The section towards fuel delivery unit 2 of hybrid channel 12 is not formed in withdrawing pattern direction 22Side is recessed. Obliquity draws like this, longitudinal axis 12.1 be parallel to perpendicular that withdrawing pattern direction 22 extendsNogata forms a sharp angle α between 18. The outside section of hybrid channel 12 is configured in integratedlyIn the circle wall 20 of storage tank 5. The compression casting that withdrawing pattern direction 22 is used by manufacture storage tank 5The direction of motion of mould is determined. Withdrawing pattern direction 22 can be perpendicular to 6 extending at the bottom of storage tank.
Hybrid channel 12 is widened in the direction of the port towards in storage tank 5, such as coniform groundWiden. At this, for example such slant setting of hybrid channel 12, make to widen part 17 towards interiorThe section of side 16 and vertical direction 18 extend in parallel.
According to the embodiment of the present invention, the storage tank 5 that has integrated hybrid channel 12 can pass throughSimple die casting casting. Hybrid channel 12 is completely integrated in storage tank 5. At this, storage tank5 have from the 6 withdrawing pattern directions 22 of extending towards unlimited end at the bottom of tank. At this, hybrid channel 12Looking up withdrawing pattern direction 22 sides towards the section of inner side 16, not form side recessed. Die casting is along withdrawing patternDirection 22 is extracted in storage tank 5. According to the embodiment of the present invention, on die casting, do not needFor the inside slide block of withdrawing pattern. In contrast, the section towards outside of hybrid channel 12 is in withdrawing pattern sideLook up and form a side recessed 19.
