Abstract
926,961. Reciprocating pumps. E. PASS & CO. Ltd. July 11, 1960 [July 10, 1959], No. 23712/59. Class 102(1). A hydraulic pump includes a rocker arm 12, two pistons 13 pivotally secured to the arm and each reciprocable in a respective cylinder 14, which has an inlet ball valve 18 from a common reservoir 31 formed by the two component parts 11a 11b of the pump body and an outlet 19 via a ball valve, Fig. 6 (not shown), to a common outlet 32, such that as one cylinder is discharged the other is filled. A ball valve pressure release mechanism, Fig. 4 (not shown), opened by a lever actuated push rod, returns liquid to the reservoir, and a pressure relief safety ball valve 33, is connected to the load side of the outlet valves 19. In another form the two pistons are oppositely directed relative to the rocker arm, the two cylinder formations having aligned axis and the actuating means being such as to cause the pistons to reciprocate in the cylinders.
