Abstract

The invention discloses a fuel shut-off electromagnet for a diesel engine. The fuel shut-off electromagnet for the diesel engine comprises a shell. The shell is cylindrical. The inner wall of one end of the shell is fixedly connected with a fixing seat. One side face of the fixing seat is fixedly connected with a rest spring and two limiting plates. The reset spring is located between the two limiting plates. The interior of the shell is fixedly connected with a circular-ring-shaped front cover and a circular-ring-shaped rear cover. A first sliding bearing is fixedly connected to the middle of the front cover. A second sliding bearing is fixedly connected to the middle of the rear cover. By the adoption of the fuel shut-off electromagnet for the diesel engine, the phenomena that a fuel shut-off electromagnet is insensitive and stuck are avoided effectively, the safety performance is high, the flexibility is good, the stability of the fuel shut-off electromagnet is guaranteed, flexible movement of a magnetic iron core and a push rod is guaranteed, the occurrence of the failure is avoided effectively, the stability is better, and the service life of the diesel engine is guaranteed effectively.

Description

technical field [0001] The invention relates to the technical field of diesel engine electromagnets, in particular to an oil stop electromagnet for diesel engines. Background technique [0002] In the fuel delivery mechanism of a diesel engine, the fuel delivery pump is fixed on the high-pressure fuel pump and driven by the camshaft of the high-pressure fuel pump. During operation, the fuel delivery pump sucks diesel oil from the diesel tank, and the impurities in the diesel oil are preliminarily filtered out by the fuel coarse filter, and then the fuel is sent into The fine filter is further filtered by the fuel fine filter. The diesel oil enters the fuel stop solenoid valve through the low-pressure fuel pipe, and then enters the high-pressure fuel pump, and is supplied to the fuel injector through the high-pressure fuel pipe. When the fuel stop solenoid valve is closed, the fuel cannot reach the high-pressure fuel pump, so that the diesel engine Cut off oil and stop. [0...
