When being applied in double fuel tank oil supply systems, which is divided into two fuel tanks of A, B, two fuel tank does not work at the same time, wherein
When A fuel tank assemblies work, oil return system is also that extra fuel oil is flowed back to A fuel tanks, does not flow into B fuel tanks；The work of B fuel tanks is former
Reason is also as A fuel tanks；This design can ensure that liquid level of fuel oil in fuel tank will not be caused to overflow fuel tank.
Description of the drawings
The specific embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the shuttle valve structure schematic diagram of the present invention.
Fig. 3 is the umbrella shape check valve structure schematic diagram of the present invention.
Specific embodiment
Attached drawing illustrates the structure of the present invention, further illustrates it in relation to details in conjunction with attached drawing below.Referring to attached drawing 1,
4 assembly of vehicle electric injection fuel pump includes oil storage barrel 2, oil storage bung 1, oil return line and oil outlet pipe, the oil storage barrel 2
Interior to be equipped with oil pump 4, oil pump take over 3 and oil inlet pipe 6,6 upper end of oil inlet pipe is connected with oil pump 4,6 lower end of oil inlet pipe and oil storage
The fuel feed hole of 2 bottoms of bucket is connected, and shuttle valve 5 is additionally provided in the oil storage barrel 2, the shuttle valve 5, which is arranged on oil return line, to be controlled
The break-make of oil return line；The fuel oil of pumping drives end transmission to coordinate with shuttle valve 5 in the oil inlet pipe 6, and oil inlet pipe 6 passes through ultrasound
Ripple is weldingly fixed in oil storage barrel 2, and oil inlet pipe 6 is fixed with shuttle valve 5 by ultrasonic bonding；The oil pump take over 3 and shuttle valve 5 pass through
Fixation is connected with oil storage bung 1 by buckle structure after ultrasonic bonding, the oil pump 4 is packed into oil pump take over 3 and passes through oil storage
