摘要： A method for manufacturing a piston ring for use in a refrigerant compressor is disclosed. The method includes the steps of disposing the piston ring in an annular groove which is formed on one end surface of a fixed holder; and pressuring the piston ring in the groove by a lower end surface of a press until the lower end surface of the press contacts the upper end surface of the fixed holder. At least one projection formed on either the fixed holder or the press contacts the piston ring. A plurality of grooves are thereby formed on one end surface of the piston ring as the pressing operation progresses.

摘要： A cylinder head for a piston type refrigerant compressor is disclosed. The cylinder head of the compressor is provided with an inner partition wall and an outer peripheral wall adapted to contact a gasket of the compressor such that the interior of cylinder head is divided into a suction chamber and a discharge chamber. The inner partition wall is made slightly longer than the outer wall such that upon mounting the cylinder head to the compressor the force pressing the inner partition wall against the gasket element is substantially equal to the force pressing the outer peripheral wall against the gasket element.

摘要： A piston-type refrigeration compressor having a more secure valve plate seal is disclosed. A cylinder housing is provided with a cylinder block having a plurality of cylinders at one end. The end surface of the cylinder block near the cylinder is coupled to a cylinder head through gaskets and a valve plate. A circular depression is formed on the end surface of the cylinder block to accommodate the gasket substantially within the depression and thereby seal the cylinder block and valve plate. In this way, the outward expansion of the gasket is prevented which prevents the gasket from deteriorating.
