ABSTRACT:
An improved wobble piston for an air compressor. The piston has a head integrally connected to a connecting rod. The connecting rod has a free end for connection to a rotating eccentric. The piston head has an internal chamber. Openings are formed through the piston head into the chamber on opposite sides of the connecting rod in a plane perpendicular to the eccentric axis. The location of the chamber openings establishes a flow of cooling air through the chamber as the piston is reciprocated in a cylinder.
