Abstract
The invention relates to a device for conveying fuel. A known device for conveying fuel has a tank flange and a storage container having a pot bottom, wherein the tank flange and the storage container are connected with each other through at least one guide rod. The storage container, along the guide rod adjustable in relation to the tank flange, is pressed by a compression spring facing away from the tank flange and has a cover. A bearing for guiding the guide rod is disposed on the cover, wherein the guide rod has a shoulder at its end facing the storage container. The disadvantage is that the compression spring and the length of the guide rod should be suitably adjusted according to the height of a fuel tank because the compression spring is disposed between the tank flange and the cover of the storage container. According to the device for conveying fuel, the adjustment of the spring element and the fuel tank at different heights can be cancelled and the same standard spring element can be used as always. According to the invention, the spring element (9) is supported with one end on the ejector (15) and with the other end on the shoulder (14) of the guide rod (8).
Description
Technical field
The present invention relates to a kind of device for conveying fuel.
Background technology
A kind of device for conveying fuel is disclosed by 10 2,007 045 178 A1 of DE, the device has one
There is tank bottoms storage tank, the case flange and the storage tank to be connected to each other by least one guide rod for case flange and one, wherein,
Storage tank can be adjusted relative to case flange along the guide rod, pressed on the direction away from case flange by compression spring, and storage tank
With a lid, cover and be provided with for guiding the bearing of guide rod at this, wherein, guide rod has on its end towards storage tank
One shoulder.Have the disadvantage, as compression spring is arranged between case flange and the lid of storage tank, it is necessary to high according to the case of each fuel tank
The adaptation for spending to be compressed spring and guide rod length respectively.
The content of the invention
According to the present invention it is proposed that a kind of device for conveying fuel, has tank bottoms storage with one case flange and one
Tank, the case flange and the storage tank are connected to each other by least one guide rod, wherein, the storage tank can along the guide rod relative to
The case flange adjustment, the storage tank are had away from pressure on the direction of the case flange, and the storage tank by a spring element
One lid, covers the bearing that is provided with the guiding for guide rod at this, wherein, the guide rod has on its one end towards storage tank
One shoulder, also, storage tank it is tank bottoms on be provided with suction jet pump, wherein, the spring element is supported on described taking out with one end
Inhale on jet pump and be supported on the shoulder of the guide rod with the other end.
Compared with the prior art, the device for conveying fuel of the invention has the advantage that, i.e. by bullet
Spring element is supported on one end on the suction jet pump being arranged on tank bottoms and is supported on the shoulder of guide rod with the other end, can be with
Save the spring element when fuel tank height is different to be adapted to and same standard spring element can be used all the time.By the knot
Structure, simplifies installation of the suction jet pump on storage tank, and improves suction and penetrate by being pressed onto the tank bottoms upper of storage tank
The function of stream pump.
By the measure listed in further technical scheme, it can be advantageous to extend and improve above-mentioned for conveying combustion
The device of material.
According to a kind of favourable configurations, spring element is arranged on a construction and is covering and to the guiding of tank bottoms direction projection
In device because can be formed by this way one by lid, spring element and suction jet pump group into cap assemblies, the cap assemblies
Particularly simple can be arranged on storage tank.The inside of storage tank is arranged in by spring element, can be increased in storage tank
Using volume.
In addition be favorably that the connection between guider and suction jet pump is so designed so that the two components it
Between on the direction of guide rod can limitedly relative motion, even if because by this way it is ensured that lid and storage tank it
Between tolerance adverse conditions under suction jet pump can also be close to storage tank it is tank bottoms on.By suction jet pump relative to leading
The nose balance of component tolerance is realized to the axial displaceability of device, wherein, suction jet pump can by the power of spring element
It is forced in the acceptance division on the bottom of storage tank by ground.
It is particularly advantageous that, suction jet pump and guider shape are connected to each other in locking manner.According to the embodiment, penetrate in suction
Implement a nipple to the projection of guider direction on stream pump, during the guider of lid extend into the nipple and this is short
Adapter is connected cohesively together with guider shape.The shape latch members setting suction jet pump is predetermined in guider
Angle position.Thus, suction jet pump is reliably reached when engaging with storage tank in the acceptance division on storage tank.
It is highly beneficial to be, during the housing of suction jet pump is loosely arranged on the tank bottoms acceptance division of storage tank and by bullet
Spring element is maintained in acceptance division by being pressed onto tank bottoms upper.Be arranged in acceptance division by suction jet pump, a small amount of fuel from
Storage tank is reached in the suction room of suction jet pump.This can correspondingly reduce the pumping power of suction jet pump.
According to an advantageous scheme, the spring element is a spiral compression spring.
Also it is favorably that the shoulder kayser is on guide rod.Such as single shoulder is that a safety collar or one can be relative to
The plastic components of guide rod kayser.If cap assemblies are had been mounted in storage tank, the plastic components of symmetric design cause also
Enough kaysers afterwards realized with guide rod.Guaranteed by the kayser with guide rod, on the one hand, the restraining forceies of a restriction are applied to fuel
Case it is tank bottoms on, on the other hand, when the device may be removed from fuel tank, also retain connection simultaneously between case flange and lid
And thus avoid the active force not allowed of the cable to the device and conduit under fluid pressure.
In addition it is favorably that guide rod is stretched out more than the shoulder with a section on its one end towards suction jet pump,
Because spring element can be by this way on the section that this stretches out in.
In addition it is favorably that tenon, at least one bridge connector or at least one rib are set on suction jet pump, because bullet
Spring element by this way can be relative to suction jet pump centering.
Description of the drawings
