Abstract

740,125. Swash-plate pumps. NEW YORK AIR BRAKE CO. April 21, 1954 [June 29, 1953], No. 11471/54. Class 102(1). In a reciprocating pump, two blocks 15, 24 are secured in a casing and each contains a series of. parallel cylinders 21 in which reciprocate pistons 30 actuated by swash-plates 26, 27. A discharge chamber 35 is formed between the blocks 15, 24 and the pistons have axial bores in which are located tubes 33 joining .opposed pistons and having ports 34 open to the pressure in the chamber 35 so that this pressure acts on the pistons and keeps them in contact with the swashplates. Radial bores 32, connected to the axial bores in the pistons, are provided to lubricate the cylinder walls. Discharge valves 42 seat on the ends of the cylinders and slide in the tubes 33 and are loaded by springs 43. The inlet openings 11, 13 communicate with cylinder ports 22 by passages 23.
