Abstract
A combination of an engine and a pump. An integral first housing section defines a portion of both the engine housing and the pump housing and has a first major surface which defines a portion of the interior engine housing surface and an oppositely disposed second surface which defines a portion of the interior pump housing surface. The first housing section has an opening and a first bearing is disposed therein. The crankshaft extends through the opening and is supported by the first bearing. A pump driving mechanism, such as a wobble plate or camming member, is coupled with the freely extending length of the crankshaft projecting beyond the first bearing. The first major surface may define an oil sump within the engine and an oil passage extending between the first and second major surfaces may communicate oil between the engine and the pump.
