Abstract

879,285. Reciprocating pumps. FRASER, A. Sept. 22, 1959 [June 22, 1958], No. 16558/58. Class 102(1). A radial-piston pump comprises hollow pistons 17 having a spring loaded suction valve 21 on their outer face such that the outer face presents a substantially unapertured surface when the valve is closed. An outlet valve 27 is provided for the head of each cylinder 24 such that when the valve is closed the cylinder head presents a substantially unapertured surface towards the piston. The pistons engage the surfaces 19 of a polygon which surrounds an eccentric 20 of the drive shaft 16, the eccentric being provided with ports 51 to admit liquid to the cylinders from an inlet 49. The outlets of each cylinder communicate by bores 32 with annular passages 33, 34. The pistons are preferably stepped and the cylinder provided with a liner 26 to provided variable volume chambers communicating by bores 57 with annular passages 58, 59 filled with liquid so that the discharge stroke of some of the pistons causes the liquid to act on the other pistons to provide the return stroke. In a modification the pistons are mechanically connected to the polygon 19.
