The technology for realizing the variable displacement of the compressor comprises an internal pneumatic control valve (internal control valve) and an external control valve (external control valve) of the compressor, wherein the application technology of the external control valve leads the internal control valve to gradually form a main flow, the external control valve of the variable displacement compressor is mainly composed of a valve body, a valve rod, a pressure sensing element (corrugated pipe), a return spring, an electromagnet (coil, a dynamic and static iron core) and other main parts, the pressure sensing element is used for sensing the pressure of an air suction cavity, the valve rod and a valve seat of the valve body form a valve port, two ends of the valve rod are respectively contacted with a movable iron core component and the corrugated pipe, the valve rod is provided with the return spring, when the coil is electrified, the movable iron core component generates thrust force moving towards the closing direction of the valve port, when the pressure Ps of the air suction cavity is high, the corrugated pipe is compressed, then the valve port is forced to be closed under the combined action of the corrugated pipe and the movable iron core component, when the pressure Ps of the air suction cavity is low, the corrugated pipe is expanded under the action of an internal spring force, the valve port is opened, and the pressure Pc of the swash plate cavity is increased, so that the compression stroke is reduced, and the displacement is reduced; the larger the valve port flow, the faster the pressure rise, and the faster the response speed of the compressor swash plate to the small angle direction adjustment. Therefore, the external control valve achieves the purposes of changing the discharge air quantity of the compressor and adjusting the temperature according to the principle of the input current value and the pressure of the suction cavity.
In the use of the automobile air conditioner, impurities from the external environment such as air, road surfaces and the like can be gradually accumulated in the air conditioner pipeline system, and part of impurities can enter the compressor cavity through the control channel of the external control valve. These impurities can move back and forth with the moving parts in the compressor chamber and enter the gaps of the moving parts, wherein smaller impurities can increase the abrasion of the moving parts (such as pistons) and lead to increased leakage and reduced refrigeration effect; the larger impurities can lead to the blockage of moving parts, unsmooth movement and even seizure of the moving parts, thereby affecting the normal operation of an automobile air conditioning system.
