The structure of the crankshaft connecting rod compressor is similar to that of the engine. Generally, the double cylinder structure is adopted. The crankshaft rotates and drives the connecting rod to make the piston move back and forth to suck in and compress the gas. The cylinder block on the upper part of the piston is equipped with intake and exhaust valve assemblies, and a shaft seal is installed between the crankshaft and the housing to prevent refrigerant leakage. In order to ensure the normal movement of parts, the crankcase is filled with a specified amount of compressor lubricating oil and oil supply facilities. Rotary swashplate compressor, also known as swashplate compressor, is a kind of axial piston compressor. At present, it is one of the most widely used air conditioning compressors.
