Abstract

The present invention relates to an inverse proportion pressure reducing valve, comprising an electromagnet assembly and a control valve assembly; the electromagnet assembly comprises a yoke, an electromagnetic coil embedded in the yoke, a static iron and a pressing plate disposed in the electromagnetic coil, a spring assembly and an ejector rod disposed in the static iron, and a magnetic shield and an armature disposed in the pressing plate; the armature is capable of axially moving along a guide sleeve by the electromagnetic coil; the spring assembly comprises an adjusting bolt and a spring; the adjusting bolt, the spring, the ejector rod and the armature are arranged along an axis from left to right in turn; wherein the ejector rod is fixedly connected to the armature which is contacted with the control valve assembly. The inverse proportion pressure reducing valve of the present invention solves the technical problems that the pressure reducing range of the pressure valve in the prior art is not wide enough, the linearity thereof is not good, and the structure is complicated; the inverse proportion pressure reducing valve has the advantages of simple structure and adaptive application.

Description

technical field [0001] The invention relates to an inverse proportional decompression solenoid valve which can continuously and proportionately control the oil pressure in the hydraulic system of the automatic transmission of automobiles or the automatic control system of industrial hydraulic pressure, belonging to the field of hydraulic control. Background technique [0002] The proportional pressure valve is a valve that continuously and proportionally controls the oil pressure remotely according to the input electrical control signal. Compared with ordinary hydraulic valves manually adjusted, electro-hydraulic proportional control valves can improve the control level of hydraulic system parameters; compared with electro-hydraulic servo valves, electro-hydraulic proportional pressure control valves are slightly worse in some hydraulic performance, but it Simple structure, strong anti-pollution ability and low cost, so it is widely used in continuous control, remote control...
