ABSTRACT:
A reciprocating, preferably a piston-type, exhauster adapted for mounting on an engine crankcase and having, on opposite sides of the piston, a high clearance volume inlet chamber and a low clearance volume exhaust chamber. The piston is operated by an engine driven cam acting on the piston rod which passes through the exhaust chamber and moves against a return spring in the inlet chamber. As the piston moves in the cylinder air is drawn from the inlet chamber through a non-return valve in the piston to the exhaust chamber and then is discharged directly into the engine crankcase.
