摘要： A reciprocating compressor includes a compressor cylinder defining a cylinder wall, a valve bore formed in the cylinder wall, and a compressor valve assembly arranged in the compressor cylinder. The compressor valve assembly includes a valve liner having a liner body and a liner flange disposed at an end of the liner body. The liner body is disposed in the valve bore. The liner flange is positioned in contact with the compressor cylinder. A valve seat is coupled to an inner surface of the liner body. The valve seat has a seating surface formed at an end of the valve seat. A compressor valve is positioned on the seating surface of the valve seat. A valve cage is positioned on the compressor valve. A valve cover is coupled to the valve cage to apply a bias force to retain the compressor valve on the seating surface of the valve seat.
