REAR HEAD SANDEN SERVICEVALVE HELLYEL

The cylinder head of the compressor in an automotive air conditioning system is a key component used to increase and control the pressure of the refrigerant in the compressor's internal chambers. The cylinder head ensures proper sealing and efficient control of the refrigerant flow, which is essential for maintaining the proper cooling performance of the air conditioning system. It is usually made of tough, wear-resistant materials to withstand high pressures and the aggressive chemical action of the refrigerant. Regular inspection and maintenance of the cylinder head is essential for the long-term efficient and reliable operation of the air conditioning compressor.
