Abstract

The invention relates to an overflow direct proportion pressure reduction electromagnetic valve with a locking function of a deep hole stop iron structure. The overflow direct proportion pressure reduction electromagnetic valve comprises yoke iron, a spring, a film, armature iron, a gasket, a bearing, an ejector rod, an O-shaped ring, a valve seat, an outlet filter screen, a mounting valve body, a ball valve seat, a ball valve body, a steel ball, a valve body, a coil, stop iron and a connector assembly. The overflow direct proportion pressure reduction electromagnetic valve with the locking function of the deep hole stop iron structure is high in pressure 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 proportional decompression solenoid valve, especially an overflow type proportional decompression solenoid valve with locking function for precise pressure control of a vehicle hydraulic system. Background technique [0002] Proportional pressure reducing valves are widely used in vehicle hydraulic systems, and driving fast-acting high-pressure clutches is the most widely used application scenario for proportional pressure reducing solenoid valves. The common positive proportional decompression solenoid valve is generally a spool type main valve structure, and it is more common to use a stepped shaft type main valve or a piston type main valve. There are also relief-type proportional pressure reducing valves, and pilot-operated proportional pressure-reducing solenoid valves that combine relief and spool valves. [0003] Chinese patent application No. 201320489551.X provides a structure of...
