ABSTRACT:
A reciprocating pump which substantially eliminates cavitation problems without imposing capacity and flow limitations to maintain a net positive suction head. The pump comprises a cylinder having a liquid inlet and a liquid outlet, a piston reciprocably movable within the cylinder and generally intermediate the liquid inlet and liquid outlet, the piston having a liqud flow conduit therethrough generally co-axial with the cylinder, the liquid flow conduit having an inlet end in liquid communication with the cylinder liquid inlet and an outlet end in liquid communication with the cylinder liquid outlet, a piston rod reciprocably movable generally along the axis of the cylinder for reciprocably moving the piston within the cylinder in a direction toward the cylinder liquid outlet and in a reciprocal direction and a valve operatively associated with an intermediate the piston rod and the piston liquid flow conduit inlet end for alternatively opening and closing the inlet to liquid flow, the valve being closed when the piston rod and piston are moved in the direction toward the cylinder liquid outlet and being open when the piston rod and piston are moved in the reciprocal direction. In one embodiment, the valve comprises a valve disk freely movable on one end of the piston rod.
