Abstract

1327356 Reciprocating pumps G LEDUC 5 June 1972 [3 June 1971] 26214/72 Heading F1A In a pump comprising a rotary swash-plate 4 which reciprocates pistons 5, liquid is supplied to the pump cylinders 7 through an axial bore 17 in the pump body 2, a chamber 9, a blind bore 15 and a kidney-shaped recess 13 in the swashplate, and passages 12, 11 in the piston slippers 10 and pistons, passages 12 sequentially registering with the swash-plate recess 13 during rotation.
