Abstract

1438189 Reciprocating pumps and motors ABEX CORP 2 Aug 1973 [16 Nov 1972] 36831/73 Heading F1A In a swash-plate pump or motor comprising a rotary cylinder block 13, Fig. 3, with pistons 16 engaging a swash-plate 19 via slippers 18, the swash-plate 19 is supported by a member 22 with an arcuate face engaging an arcuate cradle face 23, member 22 being angularly adjustable in the cradle and being anchored in its adjusted position by locking screws 45 with bevelled edges 38 engaging bevelled surfaces 47 on member 22. Screws 45 have nylon locking inserts 48. The cradle face radius of curvature is less than that of the member 22, so that member 22 engages cradle face 23 at two points, Fig. 5 (not shown). Slipperretaining plate 26 is located via thrust bearing 27 by member 28 which has a part-spherical seat engaged by part-spherical member 29, a bolt 33 securing the assembly to member 22 with limited freedom of axial movement defined by spring- loaded member 34. Member 28 is prevented from rotating by projections 31 engaging recesses 32 in member 22. Block 13 is splined on shaft 11 and secured by a bolt 39 acting via spring washers 41.
