Abstract

1,218,092. Reciprocating pumps. J. I. CASE CO. Jan. 30, 1968 [Jan. 31, 1967], No. 4626/68. Heading F1A. In a hydraulically actuated pump the valves are hydraulically actuated and the pump and valves are controlled by solenoid actuated valves such that at the end of each stroke both the inlet and outlet valves are closed. Switches are actuated by pressure build up in the actuating circuit due to the closing of all valves to initiate the next cycle.
