Abstract

1,030,991. Reciprocating pumps and motors. STEWART-WARNER CORPORATION. Jan. 11, 1963 [Jan. 11, 1962], No. 1468/63. Heading F1A. In an hydraulic pump or motor unit the drive shaft of the hydraulic unit has a cage 24 secured thereto and shoe surfaces 29 on the cage cooperate with the pistons 54 which are spring loaded. The cylinder member 46 rotates about a crank 42 on a pintle element 36 which is mounted eccentrically of the shaft 18 in the pump housing. The pintle contains axial bores 64, 66 (Fig. 2, not shown) respectively terminating in ports which communicate with openings 51 in the cylinder member. Axially spaced from the ports are part circumferential grooves which communicate with one of the opposite axial bores (Fig. 5, not shown). A restriction is provided in each communicating passage and the pressure distribution in the clearance between the eccentric 42 and member 46 substantially counteracts the radial thrust due to the pressure in the cylinders 50. The piston stroke is varied by rotating the pintle 36 and this rotation also varies the timing of the admission and exhaust. The drive shaft 18 is journalled in bearings 19, 20, the latter bearing being supported in a rim 82 joined to a hub 80 by flexible spokes 81 (Fig. 7, not shown). Lubricant is supplied under pressure through a flexible pipe 95 into two manifolds which communicate with radial bores in the hub, each having a restrictor. This bearing compensates for both axial and radial misalignment caused through the unit operating pressures.
