Abstract
1461659 Reciprocating pumps and motors E ASCHKE 3 June 1974 [30 June 1973] 24499/74 Heading F1A In a pump or motor, e.g. of tilting-head type, Fig. 1 (not shown), liquid flow to and from the cylinders is controlled by a valve plate or pintle, the dead centre lands of which are connected by a passage 34 with enlarged openings 32, 33 functioning as accumulators, the arrangement being such that pressure equalization occurs between cylinders leaving the respective inlet and outlet ports 25, 26 and communicating via passage 34. The diameter of each opening 32, 33 is greater than the spacing between the cylinder ports 23, so that pressure equalization can occur between adjacent cylinders. The spacing between the inlet and outlet ports is greater than twice the diameter of a cylinder port 23 plus the diameter of the passage opening 32, 33.
