An improved wobble piston (25) for an air compressor. The piston (25) has a head (26) integrally connected to a connecting rod (27). The connecting rod (27) has a free end (28) for connection to a rotating eccentric. The piston head has an internal chamber (34). Openings (43, 44) are formed through the piston head into the chamber (34) on opposite sides of the connecting rod (27) in a plane perpendicular to the eccentric axis (30). The location of the chamber openings (43, 44) establishes a flow of cooling air through the chamber as the piston is reciprocated in a cylinder (45). <IMAGE> |
