Problems solved by technology

In the prior art, when the car is running, it will drive the fuel pump to move together, thus generating vibration, which will cause damage to the fuel pump and greatly reduce the service life of the fuel pump of the car. In terms of long-term use, the sealing disc inside the fuel pump and the inside of the valve will continue to rub against each other. Long-term friction will cause the fuel pump to release pressure, and the pressure cannot be maintained, resulting in failure to start. Therefore, in view of the above problems Propose a kind of automobile fuel pump

Abstract

The invention relates to the field of fuel pumps, in particular to an automobile fuel pump. The fuel pump comprises a main body box, a one-way valve, a pressure reducing valve, a motor, a fuel inlet and a vibration reduction mechanism; the one-way valve is arranged in the main body box, the motor is arranged below the one-way valve, the oil inlet is formed below the motor, the vibration reduction mechanism is connected to the bottom of the main body box, and the pressure reducing valve is arranged on the left side of the one-way valve. The one-way valve is used for preventing fuel from flowing back, thus the conveying cost is saved, and meanwhile, the oil consumption is reduced; the pressure reducing valve is used for reducing oil pressure and reducing impact of the oil pressure on the automobile fuel pump; the vibration reduction mechanism is used for reducing vibration in the automobile running process, thus damage to the automobile fuel pump due to vibration is reduced, and meanwhile, oil inlet and outlet of the automobile fuel pump are promoted.

Description

technical field [0001] The invention relates to the field of fuel pumps, in particular to an automobile fuel pump. Background technique [0002] The function of the fuel pump is to deliver the fuel stored in the fuel tank to the fuel line of the injector. Before the engine is ignited, the fuel pump pressurizes the fuel in the fuel line; after the engine is running normally, the fuel pump provides a stable fuel pressure for the fuel line. In the prior art, when the car is running, it will drive the fuel pump to move together, thus generating vibration, which will cause damage to the fuel pump and greatly reduce the service life of the fuel pump of the car. In terms of long-term use, the sealing disc inside the fuel pump and the inside of the valve will continue to rub against each other. Long-term friction will cause the fuel pump to release pressure, and the pressure cannot be maintained, resulting in failure to start. Therefore, in view of the above problems An automobile...
