Abstract
1370416 Reciprocating pumps and motors ROBERT BOSCH GmbH 9 Jan 1973 [25 Jan 1972] 1093/73 Heading F1A In an axial piston pump or motor comprising a rotary cylinder block member 6 engaging a stationary ported valve plate member 9, a continuous annular bearing surface 24 is separated from sealing surfaces 21, 22 by a groove 23 and has a radial width less than that of surfaces 21, 22, such that no hydrodynamic pressure field can build up over surface 24. As shown, the surfaces are formed on the valve plate, but they alternatively may be formed on the cylinder block, Fig. 3 (not shown). The radial width of surface 24 is 0À5 to 2À5% of its external diameter. The surface area of the webs between the valve plate or cylinder ports is no more than a quarter of the surface area of the sealing surfaces. A passage 25 conveys leakage from groove 23 to the casing. The bearing and sealing surfaces may be formed on the member of higher thermal conductivity.
