CA 2099277

2099277 9311353 PCTABS00022 The design and construction of past piston assemblies having a wrist pin bolted to a connecting rod have excessive weight and structural components, and requires more complex machining techniques and tooling. The present invention overcomes these problems by providing a piston assembly (30) with a wrist pin (36) attached to a piston member (32). Thus, the length of the leg members (80) are short and do not require a portion surrounding the wrist pin (36). The results being reduced piston member (32) and piston assembly (30) weight and lower inertia, a simplified forging or casting process, a more easily machinable cavity (86) within the piston member (32) and a higher quality piston assembly (30).
