摘要： A piston rod assembly for a reciprocating compressor. The piston rod assembly may include a piston rod having a longitudinal axis and forming a piston rod neck and a piston rod shoulder. The piston rod may include a first end integral or coupled with a piston head and a second end axially opposing the first end and configured to couple with a crosshead including a flange. An inner surface of the flange may have a Brinell hardness. The piston rod assembly may also include a cylindrical sleeve disposed circumferentially about the piston rod neck. The cylindrical sleeve may have a lower Brinell hardness than the Brinell hardness of the inner surface of the flange.

摘要： A reciprocating compressor with an improved valve assembly is disclosed. Compressor includes a cylinder block having a cylinder that defines a cylindrical bore extending longitudinally along a bore axis. Cylinder block includes a hollow chamber extending longitudinally along a chamber axis, which is non-intersecting relative to the bore axis. Valve assembly is disposed in hollow chamber. Valve assembly is made up of an axially-stacked arrangement of components extending along chamber axis. The axially-stacked arrangement of components is spaced apart from a wall that forms a perimeter of the cylinder and is thus free from mechanical interference with the perimeter of the cylinder.

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.
