Abstract

A wobble piston is provided to be used in an air compressor for providing compressed air, and includes a piston cap having a generally flat first plate and a peripheral edge extending downwardly from the first plate. A connecting support rod is connected to the piston cap, and a compression ring is clamped between the edge of the piston cap and the support rod in complementary fashion. Upon assembly between the cap and the support rod, the compression ring has an angled side wall that is bent upwardly inwardly at a predetermined obtuse angle relative to a longitudinal axis of a cylinder.
