Problems solved by technology

Although this can be achieved by designing a complex piston head shape, such a complex shape is quite expensive to manufacture, assembly becomes more difficult, and throttling losses usually occur when the piston reaches the center of the upper dead center

Embodiment Construction

[0021] The following descriptions of preferred embodiments are illustrative only and in no way limit the application or uses of the present invention. exist figure 1 In Figure 8 there is shown a compressor unit 10 which employs a unique discharge valve retainer according to the present invention. Compressor assembly 10 includes: a compressor body 12 ; a compressor cover 14 ; a cover gasket 16 ; a valve plate assembly 18 and a valve plate gasket 20 .

[0022] The compressor body 12 defines a pair of compression cylinders 22 within which a piston 24 is slidably disposed. Each compression cylinder 22 communicates through the valve plate assembly 18 with a discharge chamber and a suction chamber.

[0023] The valve plate assembly 18 includes: an upper valve plate 26 ; a lower valve plate 28 ; and an annular gasket 30 . The valve plate assembly 18 defines a pair of suction passages 32 and a pair of discharge passages 34 . Said suction passage 32 communicates with the suction ch...

Abstract

A discharge valve retainer is manufactured from powder metal using FLC4608, FL4405, FC0205 or FC0208 material. The finisher retainer has a density of approximately 6.8 to 7.6 gm / cc. The retainer is carbonitrided, quenched and tempered to achieve a surface hardness of Rockwell 15N 89-93. The exterior of the retainer is contoured to provide for the non-turbulent flow of pressurized gas around the discharge valve.

Description

technical field [0001] The present invention relates generally to refrigeration compressors. More specifically, the present invention relates to a reciprocating piston refrigeration compressor having a discharge valve retainer of a unique design which improves the reliability of the refrigeration compressor , which improves performance. Background technique [0002] Reciprocating piston compressors typically employ a valve assembly actuated by suction and discharge pressures mounted to a valve plate assembly mounted at the end of a cylinder defined by the compressor body. The valve plate assembly is usually sandwiched between the compressor cover and the compressor body. A valve gasket is installed between the valve assembly and the compressor main body to seal the contact surface. [0003] Typically, the discharge valve assembly includes: a discharge valve element engaged with a valve seat defined by the valve plate assembly; a discharge valve retainer for securing the d...
