Embodiment
Do to know to the utility model by reference to the accompanying drawings below by way of preferred embodiment and intactly illustrate.
Be placed in the electric fuel pump assembly of fuel tank, as shown in Figure 1, it comprises fuel pump core 6, base 3, unidirectional oiling valve 13, upper cover 1, oil outlet tube 12, return tube 11, pressure regulator valve 2.
Upper cover 1 includes lid 103, filler opening 105, oil outlet 104, terminal box 106.
Lid 103 comprises an oil-feed runner, a fuel-displaced runner, and filler opening 105 is connected with oil-feed runner one end, and pressure regulator valve 2 is connected with the other end of oil-feed runner, and oil outlet 104 is connected with fuel-displaced runner one end, and oil outlet tube 12 is connected with the fuel-displaced runner the other end.
Base 3 inside has cavity, and the top of base 3 is provided with open port, in the present embodiment, and the mouth of pipe that this open port 15 opens for column.
Base 3 being provided with pressurized hole 7, for carrying out supercharging to the oil plant entering base 3, making it spray in the cavity of base 3.Unidirectional oiling valve 13 is arranged at the bottom of base 3, can make the oil plant outside base 3 under a certain pressure in fuel tank by the outside unidirectional inflow base 3 of base 3.Fuel pump core 6 is arranged among base 3 and fixes with base 3.
The top of base 3 is provided with baffle plate 9, and baffle plate 9 sprays outside base 3 for preventing oil plant.In this enforcement, baffle plate 9 is buckled in the top of base 3.Compact structure, installation and maintenance are convenient.
Fuel pump core 6 is provided with filtrating equipment 14.Electric fuel pump assembly is also provided with a fuel level sensor 10, in order to find out the height of oil level.
Be provided with snap ring between pressure regulator valve 2 and upper cover 1, pressure regulator valve 2 is connected by snap ring with upper cover 1, can ensure under certain join strength, easy for removal and installation and daily maintenance and maintenance.
Upper cover 1 being also provided with a terminal box 106, for connecting the cable of fuel pump core 6 and fuel level sensor 10, fuel pump core 6 and fuel level sensor 10 can being electrically connected with car running computer.
As shown in Figures 1 and 2, the concrete annexation of electric fuel pump assembly remaining part is as follows: one end of return tube 11 is connected with the oil-feed runner of upper cover 1, the other end of return tube 11 is connected with the pressurized hole 7 on base 3, one end of oil outlet tube 12 is connected with fuel pump core 6, and the other end of oil outlet tube 12 is connected with the fuel-displaced runner of upper cover 1.
