Abstract

1,146,966. Reciprocating pumps. HYDROMATIK G.m.b.H. July 12, 1966 [Aug.11, 1965], No.31344/66. Heading F1A. A multiple delivery, swash-plate or tilting-head pump has stepped pistons 7', the stepped portions of which work in separate pumping chambers 8', 9' with separate connections 5', 6' to a ported valve block 20 which has a common inlet port 1' and separate delivery ports 18, 19. In the tilting-head embodiment, Fig. 1 (not shown), the separate delivery conduits (16), pass through the pivots (17) of the head assembly.
