ABSTRACT:
An air compressor cylinder sleeve is formed from an extrusion having a central passage surrounded by a plurality of closed sided passages. Preferably, grooves are formed between adjacent ones of the closed sided passages. The extrusion is cut into individual cylinder sleeves which are mounted on compressor housings. The central passage receives a piston which is reciprocated by an eccentric on a motor shaft. The ends of the closed sided passages adjacent the housing open into the interior of the housing and the opposite ends of the passages open to atmosphere. A fan on the motor shaft causes air to flow through the compressor housing and through the closed sided passages to cool the cylinder sleeve.
