Example Embodiment

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] See figure 1 The present invention provides a reverse proportional reduced electromagnetic valve with a shirt and a pole shoe integrated piston structure, from the yoke 1, gasket 2, main spring 3, armature 4, connecting member 5, film 6, magnetic board 7, the valve body 8, the spool 9, the piston 10, the reset spring 11, the valve seat 12, the coil 13, and the retaining iron 14.

[0020] The yoke 1 is cylindrical, and there is a flat bottom blind hole, which is composed of a soft magnetic metal material and is integral with the lower magnetic board 7. The gasket 2 is a circular thin sheet, which is composed of a non-ferromagnetic material, which is close to the bottom of the blind hole inside the shirt 14. The main spring 3 is a cylindrical compression spring, which is composed of a metal, and the end surface is located in the bottom of the baffing 14, and the lower e...

Abstract

The invention relates to an inverse proportion pressure reduction electromagnetic valve of a stop iron and pole shoe integrated spherical piston structure. The inverse proportion pressure reduction electromagnetic valve comprises yoke iron, a gasket, a main spring, an armature, a connector, a film, a lower magnetic circuit board, a valve body, a piston, a reset spring, a valve seat, a coil and stop iron. The inverse proportion decompression electromagnetic valve of the stop iron and pole shoe integrated 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 an inverse proportional decompression solenoid valve with an integrated spherical piston structure of a stopper and a pole shoe, which is used for precise pressure control of a vehicle hydraulic system. Background technique [0002] The inverse proportional pressure reducing valve is widely used in the vehicle hydraulic system to control the hydraulic pressure to drive the mechanical mechanism, especially the engagement of the high pressure clutch in the gearbox. [0003] Chinese patent application number "200880005948.9" provides a typical structure of a two-position three-way inverse proportional decompression solenoid valve. The magnetic shunt structure is formed by combining the pole shoe (serial number 35 in the attached drawing of the patent), the stop iron (serial number 34 in the attached drawing of the patent) and the armature (the serial num...
