Abstract

953,927. Reciprocating pumps. RECHERCHES ETUDES PRODUCTION. Aug. 15, 1961 [Sept. 1, 1960], No. 29470/61. Heading F1A. [Also in Division F2] A radial cylinder pump has a delivery chamber 22 having a transverse radial face 23 into which open passages 21 from the cylinders 6; in one embodiment an annular metallic valve member 24 overlies the face and controls flow through the passages 21 by local deformation. The valve member 24 may be pressed axially by a plurality of rubber blocks 31 (Fig. 3) or by springs or be axially resilient. In another embodiment, a hinged valve is provided for each pair of ports, the valve being attached either to the block 1 or cover 2. In a modified pump two radial faces and delivery chambers are provided and the cylinder ports open to one or other of the radial faces, the chambers having separate outlets. The delivery chambers may be concentric or coaxial and more than two may be provided to give multiple outlets. The pump may comprise two adjacent groups of cylinders each group supplying two outlets. Inlet may take place through the drive shaft 7 and passages in the polygonal eccentric member 10 and piston 12. In the embodiment shown each piston has a peripheral port 38 which clears the inner edge of the cylinder to communicate with a chamber 36 fed by a centrifugal pump 37 on the drive shaft.
