Abstract
1355079 Reciprocating pumps and motors CESSNA AIRCRAFT CO 14 May 1971 [18 May 1970] 14918/71 Heading F1A In a swash-plate pump or motor comprising a rotary cylinder block 20 with pistons 26 engaging a swash-plate 12, a bearing plate 43 is interposed between the piston slippers 41 and the swash-plate surface and rotates with the slippers, the plate 43 being radially located by partspherical members 55, 56 between the plate 43 and the drive-shaft 15. In the motor embodiment shown, a second set of pistons 25 engage a second swash-plate member 32 via a bearing plate 29 and rollers 31. Liquid flow to and from cylinders 24 is via piston, slipper and bearing plate passages 38, 42, 44, the bearing plate passages registering sequentially with inlet and outlet ports in swash-plate 12. Lands surrounding the bearing plate passage ports 44 constitute a hydrostatic bearing supporting the bearing plate on the swash-plate. A spider plate 50 holds slippers 41 in contact with bearing plate 43 and is connected to plate 43 by projections 53 engaging slots 54 in plate 43. A spring 57 acts between block retainer 37 and member 56. In Fig. 4 (not shown), a pump has a single set of pistons in a block with cylinder ports registering with a ported valve face, the spider plate being coupled to the bearing plate by rivets.
