Car air conditioning compressor valve plate

As a core component of the vehicle's refrigeration system, the automotive air conditioning compressor valve plate is responsible for controlling refrigerant flow and regulating the compression cycle, directly affecting the air conditioning's cooling efficiency, energy consumption, and operational stability. The valve plate mainly consists of the valve plate body, suction and discharge valve assembly, and sealing structure. It must maintain stable performance under complex vehicle operating conditions (such as high temperatures, vibrations, and bumps).

Product Details


The car air conditioning compressor valve plate, as a core component of the vehicle refrigeration system, plays a key role in controlling the refrigerant flow and regulating the compression cycle, directly affecting the air conditioning refrigeration efficiency, energy consumption performance, and operating stability. The valve plate mainly consists of the valve plate body, suction and discharge valve assembly, and sealing structure, and needs to maintain stable performance under complex vehicle operating conditions (such as high temperature, vibration, and bumps).

The valve plate body is usually made of high-strength aluminum alloy or titanium alloy material, and is precisely processed and formed, combining lightweight and high rigidity characteristics. It can withstand instantaneous high pressure of up to [X] MPa inside the compressor and resist chemical corrosion of refrigerants (such as R134a, R1234yf). The suction and discharge valve assembly uses a reed valve or ball valve structure. The reed valve uses an ultra-thin elastic steel sheet to achieve rapid opening and closing, with a response time of only milliseconds; the ball valve relies on the precise sealing of the spherical valve core and is suitable for high-pressure variable displacement compressors. These valve ports, through optimized fluid channel design, can reduce gas flow resistance by [20-30]%, significantly improving compressor volumetric efficiency.
