Abstract

740,784. Reciprocating pumps and compressors. LUCAS (INDUSTRIES), Ltd., J. July 28, 1954 [Aug. 17, 1953], No. 22581/53. Classes 8(1) and 102(1). In a reciprocating pump or compressor the body a has at least one radial cylinder fitted with a piston d having a port e and engaging a flat face on a sheave g mounted on an eccentric h. Fluid flows from the chamber c through groove n, in the sheave, and port e during the suction stroke and is delivered through port e and port o in the sheave which co-operates with a cut-away portion i of the eccentric that is in communication through passage r with an axial bore q in the eccentric shaft. The pistons d may be pressed against the sheave by springs f or each opposite pair of pistons may be connected by a yoke which engages grooves in the pistons and surrounds the eccentric shaft.
