Abstract
The utility model relates to an electromagnetic oil pump valve which comprises an oil inlet duct, an oil outlet duct and a shell. An electromagnetic valve enabling the oil inlet duct and the oil outlet duct to be opened or closed is arranged inside the shell. The electromagnetic oil pump valve further comprises a copper tube and a connector. One end of the copper tube is inserted into a coil former. A movable iron core is arranged inside the copper tube in an axially-movable mode. A static iron core is coaxial with the movable iron core. One end of the static iron core is in threaded connection with the inner wall of the copper tube. The extending end of the static iron core is provided with a nut which is in screw-thread fit with the extending end of the static iron core. The connector is in screw-thread fit and connection with the copper tube. A containing cavity is formed between the connector and the copper tube. The oil inlet duct and the oil outlet duct are coaxially arranged at the two ends of the connector respectively and communicated with the containing cavity. An oil inlet hole corresponding to the containing cavity is formed in the oil inlet duct. When the movable iron core moves axially, the oil inlet hole is closed or opened. According to the technical scheme, the electromagnetic oil pump valve has the advantages of effectively improving the sealing performance, preventing leakage and being convenient to assemble.
