摘要： A horizontal piston compressor is disclosed, including a frame with a cylinder, and a piston reciprocably received in the cylinder. The piston has an inner chamber and first and second end walls. The piston and the cylinder form a compression chamber for compressing the gas. A valve and an orifice are disposed in the first end wall, and are configured to supply gas from the compression chamber to the inner chamber during a compression stroke of the piston. A gas bearing supports the piston relative to the frame. The gas bearing includes an opening for supplying gas from the inner chamber to a space between the piston and the cylinder such that the gas supplied to the space exerts an upward pressure on the piston. The valve may be a spring-loaded valve, and the orifice may be an orifice insert positioned between the valve and the compression chamber.

摘要： A connecting rod (24) has a modified end adapted to ensure that a lubricant film of sufficient thickness exists in an end bearing thereof when the connecting rod is placed in both tension and compression. The connecting rod includes an elongated body portion or shaft (40), a big end (42) defining a first coupling bore (44) at a first longitudinal end of the body portion (40), and a small end (46) defining a second coupling bore (48) at a second longitudinal end of the body portion (40). The small end (46) and the big end (42) each have a proximal side (50,52) nearest the shaft (40) and a distal side (54,56) furthest from the shaft (40). An opening (100) is formed in the shaft (40) adjacent the proximal side (52) for adjusting a stiffness of the proximal side (52).
