Abstract

927,005. Reciprocating pumps. T. BUDZICH. May 2, 1961, No. 15790/61. Class 102(1). [Also in Group XXIX] In a swash plate pump or motor having a stationary cylinder block and a rotary swash plate 17 coupled to a rotary, semi-circular valve plate 30, a stationary balancing ring 43, having bores 42 corresponding to the cylinder bores 13 and housing pistons 48 engaging the end of a housing 12, is provided to maintain valve plate 30 in contact with the cylinder block. Balancing ring 43 is spring-biased against valve plate 30 for starting. Further balancing of the loads on the valve plate is effected by a reaction piston 24, formed on the end of drive shaft 22, and a high-pressure sleeve 45 slidably mounted in the high pressure port 47. As a pump, liquid enters cylinders 13 via port 60 and casing 12 and is delivered via passages 27, 34, 35, 36, sleeve 45 and port 47. The end faces of the cylinder block and balancing ring are hydraulically relieved.
