Monostable or bistable electro-valve for use in high pressure fuel system of engine of aircraft, has drive unit for shifting push rod by mobile core such that translation of mobile core produces translation of shifted push rod in time

摘要

The electro-valve (10) has a push rod (18) connected to a valve (15), where air gap (14) is formed between a mobile core (17) and a fixed reinforcement part (11). A coil (13) produces magnetic field that is guided by the reinforcement part and the mobile core to create magnetic force in the air gap when the coil is supplied with electrical current. A drive unit shifts the push rod by the mobile core such that mobile translation of the mobile core produces translation of the shifted push rod in time.
