Abstract

The invention relates to a stop iron and pole shoe integrated overflow type inverse proportion decompression electromagnetic valve with an unloading function. The stop iron and pole shoe integrated overflow type inverse proportion decompression electromagnetic valve comprises an adjusting screw, a gasket, stop iron, a film, an armature, a valve body, a bearing, an ejector rod, a valve seat, a steel ball, a ball valve body, a mounting valve body, an outlet filter screen, a ball valve seat, an inlet filter screen, an O-shaped ring, a coil, an adjusting spring, yoke iron and a connector. The stop iron and pole shoe integrated overflow type inverse proportion decompression electromagnetic valve with the unloading function is high in adjusting precision, small in pressure fluctuation, long in service life, good in anti-pollution capacity and good in manufacturing manufacturability.

Description

technical field [0001] The patent of the present invention relates to an overflow type inverse proportional decompression solenoid valve, especially an overflow type inverse proportional decompression solenoid valve with unloading function for precise pressure control of a vehicle hydraulic system. Background technique [0002] Inverse proportional pressure reducing valves are widely used in vehicle hydraulic systems to control hydraulic pressure to drive mechanical structures. Generally speaking, the inverse proportional pressure reducing valve is divided into three categories, direct acting inverse proportional pressure reducing solenoid valve, overflow type inverse proportional pressure reducing solenoid valve and pilot type inverse proportional pressure reducing solenoid valve, among which the pilot type inverse proportional pressure reducing solenoid valve can be considered as overflow Type pressure reducing valve and direct acting pressure reducing valve combination. ...
