ABSTRACT:
In a camshaft drive housing for an internal combustion engine supporting auxiliary equipment, an oil pump is mounted in the housing cover and driven by the engine crankshaft. It supplies oil under pressure to an oil filter also mounted on the camshaft drive housing and the pressure of the oil leaving the oil filter is communicated back to the oil pump by way of a passage extending through the housing cover for controlling the oil pump.
