ABSTRACT:
An improved ram pump of the type having a pump housing (7) an inlet (8) for intake of fluid, a reservoir (10) for supply of a dynamic fluid head to the pump, a release valve mechanism (11) for exhaust of fluid from the pump and a lift valve mechanism (12) for output of back pressure generated by the pump. The improvements comprise a partially spirally wound lead pipe (9) connecting the reservoir to the pump inlet, an adjustable release valve mechanism (11) having a valve cup (13) and annular adjustment ring (21) which cooperate to form variable outlet ports (23) that selectively restrict exhaust of fluid to vary the height of fluid above the valve (16) and a lift valve mechanism (12) biased at a pressure greater than approximately 10 gm/cm.sup.2.
