Because the gas compressor, motor generate heat and mechanical friction generate a lot of heat, different temperature distributions are generated inside the compressor, with higher temperatures generated at the upper compressor cylinder and cylinder end face, and lower oil temperatures at the lower part; the higher the temperature in the cylinder, the greater the power consumption generated during the compression process. In a reciprocating crankshaft connecting rod piston compressor, the oil in the lower oil pool is generally thrown to the cylinder through the high-speed rotation of the crankshaft, which cools the cylinder.

[0003] The cylinder seat is a carrier that supports the moving parts. In addition to supporting the piston movement, the cylinder part of the cylinder seat is also used to provide a sealed space for compressed gas.

An annular hollow oil groove 4 is provided to facilitate the oil to heat exchange and cool the outer ring of the piston connecting tube 5, so as to avoid the problem of overheating of the suction air and reduced working efficiency caused by the increase of the cylinder head temperature. A reinforcing rib 7 is provided in the annular hollow oil groove 4 to strengthen the front side of the piston connecting tube 5 to ensure the working stability of the piston.
