ABSTRACT A flexible valve retainer for a piston and suction valve assembly of a reciprocating piston hermetic compressor assembly. In the compressor assembly, the suction valve opens as a result of the fluid pressure generated by the reciprocating movement of the piston in the cylinder. As it opens, the suction valve is axially displaced from a closed position on the top surface of the piston to an open position a fixed distance therefrom, whereupon further axial movement is prevented as the suction valve strikes the valve retainer. The radially outer portion of the valve retainer deflects as a result of the impact with the suction valve. This deflection of the valve retainer lessens the detrimental effects caused by repeated impact between the suction valve and retainer. The valve retainer is formed from a flexible material such as spring steel or Swedish steel. The valve retainer comprises at least one washer coaxial with the suction valve, and spaced said fixed distance therefrom. In a preferred embodiment, the valve retainer comprises two or three washers stacked one atop another. The stiffness of the valve retainer is less than about 331,000 lbf/in, and the thickness of the valve retainer is preferably between about 0.028 and 0.060 inch.
