Abstract

See full text

A piston assembly that includes a pair of piston members that are formed of compacted powdered metal. The piston members have sets of locking features that include alternating projections and recesses that are spaced circumferentially about and intersect a rod aperture that extends through the piston member. Each projection is formed along a projection axis, which extends radially from a center axis along which the rod aperture is formed, and has a pair of opposite side walls and an end wall that connects the side walls to one another on a side of the projection that is opposite the rod aperture. The recesses on each piston member are configured to matingly and frictionally receive the projections on the other piston member.
