Abstract
An improved slant axis rotary mechanism of the type including a housing defining a chamber having a radially outer spherical wall and a radially inner spherical wall interconnected by opposed, generally radially extending side walls. A shaft is journalled within the housing and has an angularly offset portion within the chamber. A rotor is within the chamber and journalled on the angularly offset portion. The mechanism is provided with an improved cooling system including a plurality of coolant receiving conduits in the walls in close proximity to the chamber. A thin, wear resistant layer is disposed on the walls within the chamber and interiorly of the conduits. The conduits are located closely adjacent the intersections of the side walls and the spherical walls to provide excellent cooling.
