Abstract

The invention relates to a stop iron and pole shoe integrated direct proportion pressure reduction electromagnetic valve of a spherical piston structure. The stop iron and pole shoe integrated direct proportion pressure reduction 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, a yoke, a connector and the like. The stop iron and pole shoe integrated direct proportion pressure reduction electromagnetic valve of the spherical piston structure is high in adjusting precision, small in pressure fluctuation, long in service life, high in anti-pollution capacity and good in manufacturing manufacturability.

Description

technical field [0001] The patent of the present invention relates to a proportional decompression solenoid valve, especially a proportional decompression solenoid valve with an integrated stop iron and pole shoe and a spherical piston structure for precise pressure control of a vehicle hydraulic system. Background technique [0002] Proportional pressure reducing valves are widely used in vehicle hydraulic systems to control hydraulic pressure to drive mechanical mechanisms, especially to drive the engagement of high-pressure clutches. [0003] The invention patent of Chinese patent application number 200910024360.4 provides a structure of a proportional decompression solenoid valve. The proportional electromagnet part adopts a typical stopper, armature and pole piece to form a magnetic shunt, so that the electromagnet can control the input signal according to the Proportional output electromagnetic force. This typical proportional electromagnet structure requires high par...
