Abstract
A die cast aluminum piston for a reciprocating compressor. The piston is cast with no coring and thus includes no aperture in the as-cast piston for a wrist pin. The aperture for the wrist pin is subsequently formed in the wrist pin in a preselected location after casting. The wrist pin is formed of a preselected diameter. Because the wrist pin can be placed in a preselected location with a preselected diameter, the same cast piston design can be used in a plurality of applications by varying the location of the aperture or the size of the aperture, or both.
