Abstract

1371243 Reciprocating pumps J WAGNER 6 Dec 1971 [21 Dec 1970] 56537/71 Heading F1A In a hydraulically-actuated pump, e.g. supplying paint to a spray gun 8, comprising a piston or diaphragm 10 reciprocated by a liquid column driven by a piston 14, the liquid column comprises a liquid, e.g. oil, with 4-8% by volume of a gas, e.g. air, dissolved in or mixed with it, such that when the pump outlet is closed or throttled e.g. by spray gun control 9, the gas comes out of solution during the subsequent suction stroke to prevent vapourization of the liquid and cavitation, an adjustable valve 19 relieving the column pressure during the discharge stroke and limiting the pump output pressure. The pump inlet valve 5 is spring-loaded such that pumping chamber 2 never completely fills, resulting in a dead space D to permit some movement of diaphragm 10 on its delivery stroke when the pump outlet is closed. An inlet 21 for flow of make-up liquid from reservoir 17 into the column is controlled by piston 14. Swash-plate 15 driving piston 14 is mounted on a flywheel driven by electric motor 16.
