Abstract
1,232,075. Reciprocating pumps. TOWLER HYDRAULICS Ltd. June 30, 1969 [July 4, 1968], No.32022/68. Heading F1A. In a swash-plate pump comprising pistons 26 reciprocated by swash-plate 31 and drawing from chamber 34 via valve 35 and discharging via valve 32, the delivery is regulated by a valve assembly B removably mounted in the pump casing, and comprising piston valves 25 each controlling a by-pass passage 27, 28 leading from a respective pumping cylinder to inlet chamber 34, Valves 25 are reciprocated by a swash-plate 1 splined for axial movement on, and driven by, an extension 2 of the pump drive-shaft 3. A spring 21 biases swash-plate 1 against a thrust plate 4 which is axially adjustable by a hand wheel 9, actuating a screw assembly 10 with adjustable stops 15, to adjust the axial position of valves 25 relative to by-pass passages 27, 28, and hence regulate the pump delivery,
