Abstract
A spring must be engaged and deformed by the suction valve in order for the suction valve to seat. The spring provides an opening bias to the suction valve with negates most, if not all, of the effects of adhesion due to the presence of a thin oil film between the suction valve and suction valve seat when the suction valve is closed. Accordingly, the opening of the suction valve takes place sooner in the suction stroke and is essentially solely responsive to the differential pressure across the suction valve.
