Abstract

700,824. Swash-plate pumps. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M. Aug. 3, 1951 [Aug. 8, 1950], No. 18467/51 Class 102 (1). In a swash-plate pump, the cylinders are formed in a fixed body 6 and the pistons 7 are actuated by a swash-plate 9 bearing through balls 10 on a hemispherical intermediate member 36 supported within a hemispherical rotor 37 attached to the driving shaft and supported in the casing by balls 12. Keys 38 carried by the intermediate member engage keyways 37b in the rotor to transmit rotary motion but permit the intermediate member to rock to vary the stroke of the pistons 7. The intermediate member is adjusted by an oblique surface 39a on the cylinder 39 engaging the surface 40a of a roller 40; the cylinder 39 is moved by a nut 41 through the intermediary of balls and cylinders 42, 43. The pistons 7 carry inlet valves 20 the lift of which is limited by stops 21. Specification 672,173 is referred to.
