Problems solved by technology

[0005] Since the coil is made of a large number of copper wires, the cost is high and the coil volume is large, so there is an urgent need for an electric control valve that uses less copper wire and is smaller

Embodiment Construction

[0034] refer to figure 2 as shown, figure 2 It is a sectional view of the electric control valve of the present invention. The electric control valve includes: an air supply channel 16 composed of a valve cavity 12, a first valve port 13, a second valve port 14, and a communication channel 17. The air supply channel 16 communicates with the air conditioner compressor exhaust pressure zone Pd, the crank Chamber pressure zone Pc and valve chamber 12. Wherein, the first valve port 13 extends radially from the valve cavity 12 , and the downstream portion of the gas supply passage 16 is constructed to establish communication between the valve cavity 12 and the crank cavity pressure zone Pc. The second valve port 14 extends radially from the communication passage 17 and constructs the upstream portion of the air supply passage 16 to connect the communication passage 17 with the discharge pressure zone Pd of the air conditioner compressor. Thus, the air supply passage 16 constru...

Abstract

The present invention discloses a electrical controlled valve in discharge variable compressor, which includes a gas supply passageway, a pressure sensor and a valve rod, also includes: valve case that fixedly connects with the gas supply passageway and the pressure sensor, wherein the valve case includes a coil cavity, and the valve rod extends into the coil cavity in the valve case; a permanent magnet component that contained in the coil cavity; a coil that disposed in the coil cavity and nested inside the permanent magnet component; a offsetting spring that disposed on the top of the coil cavity and between the permanent magnet component and the valve case, and the offsetting spring generates reset force to the valve rod; a electrical source component that connects with the coil and control electrical current size to be inputted into the coil according to external signal, wherein, after the coil electrified, electromagnetic force is generated between the permanent magnet components to make the permanent magnet component perform relative movement to the coil, so as to drive the valve rod move and adjust jaw opening of the valve rod.

Description

technical field [0001] The present invention relates to the control technology of the variable displacement compressor, and more particularly, relates to the electric control valve of the variable displacement compressor. Background technique [0002] At present, electronically controlled valves are mostly used as control devices for variable discharge compressors. Its main function is to control the displacement of the compressor through the suction pressure of the variable displacement compressor and the external control current. Such as figure 1 As shown, the electronic control valve changes the opening of the valve port by sensing the suction pressure Ps and controlling the current, thereby changing the conduction degree from the exhaust pressure Pd to the crank chamber pressure Pc to adjust the crank chamber pressure Pc. The pressure difference between the discharge pressure Pd and the crank chamber pressure Pc determines the compressor swash plate angle, that is, the...
