The invention discloses a fuel pump provided with a damping mechanism. The fuel pump comprises a housing, wherein a pump main body is mounted in the housing; two lantern rings are arranged on the outer sides of the housing in a sleeving manner; two slant support legs are welded at the bottom of each of the two lantern rings; a horizontal support block is integrally formed at one end, far away fromthe corresponding lantern ring, of each of the support legs; a mounting screw hole is formed in the support block; support rods perpendicular to the housing are welded on the outer surface of the housing at equal intervals; and support plates equal to the support rods in amount are arranged on the inner side face of each of the lantern rings. According to the fuel pump, the lantern rings are arranged on the outer sides of the housing in a sleeving manner, a buffer spring is mounted between each of the lantern rings and the housing, and the buffer spring is utilized to buffer and counteract vibration generated by the housing, so that normal operation of the fuel pump is ensured and the service life of the fuel pump is prolonged; the support plates and the support rods are in pin joint to limit the housing, so that the housing is prevented from generating large-scale deviation, and the stability is higher.
Description
technical field [0001] The invention relates to the field of auto parts, in particular to a fuel pump with a shock absorbing mechanism. Background technique [0002] Fuel pump is a term in the auto parts industry. It is one of the basic components of the fuel injection system of EFI vehicles. It is located inside the fuel tank of the vehicle. The fuel pump works when the engine is started and the engine is running. If the engine stops and the ignition switch is still ON, the HFM-SFI control module turns off the power supply of the fuel pump. to avoid accidental ignition. The function of the fuel pump is to suck the fuel out of the fuel tank, pressurize it and deliver it to the fuel supply pipe, and cooperate with the fuel pressure regulator to establish a certain fuel pressure. The fuel pump is composed of an electric motor, a pressure limiter, and a check valve. The electric motor actually works in the fuel in the pump casing. There is nothing in the casing that can be ig...
