Abstract

1416859 Hydraulic pumps or motors D FIRTH K FOSTER and C J HOOKE 9 Nov 1972 [19 Oct 1971 4 Aug 1972] 48604/71 and 36447/72 Headings F1A and F1P A reciprocatable device comprises an outer member 112, an inner member 114 reciprocable relative to the outer member 112, a resilient member 116 connecting the members 112, 114 together, the resilient member having an average thickness in a direction normal to the axial direction not greater than the average length of the resilient member in the axial direction, and a piston 120 slidable in the end 122 of the outer member and defining therewith a chamber 126 for fluid, especially liquid. In operation the inner member 114 is either reciprocated by the piston 120 due to the application of a pulsating pressure to the chamber 126 or is reciprocated to change the pressure in the chamber 126 for use in pumping. For other instructional details of the device and also details of two systems, Figs. 3 and 4 (not shown) for producing pulsating pressure in the chamber 126 -See Specification 1416860.
