摘要： A compressor (20) has a case (22) and a crankshaft (38). The case has a number of cylinders (30-32). For each of the cylinders, the compressor includes a piston (34) mounted for reciprocal movement at least partially within the cylinder. A connecting rod (36) couples each piston to the crankshaft. A pin (44) couples each connecting rod to the associated piston. Each pin has first (52) and second (53) end portions mounted to first (56) and second (57) receiving portions of the associated piston and a central portion (48) engaging the associated connecting rod. For each of the pistons a pair of first and second at least partially non-metallic plugs have respective stems received in the pin first and second end portions and respective heads facing a wall surface of the associated cylinder.

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).

摘要： An improved piston pin retention button device having a body portion and at least one locating tab extending outwardly from said body portion for mating engagement with a corresponding tab cutaway formed in a piston device. The inclusion of said locating tab and corresponding opening in said piston device prevents rotation of the button device in the piston device. Other embodiments of a piston pin retention button device are also disclosed and prevent the unwanted rotation of the button device in the piston device, and permit the oil ring to function as designed. Other alternative embodiments of a piston pin retention button device are also disclosed that prevent unwanted rotation of the button device in the piston device.

摘要： A wrist pin and wrist pin retainer are combined in a subassembly which prevents inadvertent removal of the retainer from the assembly. The subassembly is placed in a bore defined by a piston and a connecting rod with at least one annular groove formed in the bore. When the subassembly is located in the bore, the retainer coacts with the annular groove to secure the wrist pin in the bore.

摘要： A piston assembly is disclosed having a wrist pin for pivotably attaching a connecting rod to a piston for use in an internal combustion engine. The wrist pin is formed from an elongated circular cylindrical body having a pair of deformable sections formed adjacent each end and a relatively hard middle section therebetween. The wrist pin is sized for insertion along a longitudinal axis defined by a pair of coaxially aligned, spaced apart bores formed in diametrically opposed portions of the piston. The deformable end sections are adapted to be deformed sufficiently to engage the bores of the piston to limit the axial movement therebetween. The relatively hard middle section spans between the bores in the piston for pivotably engaging one end of the connection rod.
