Abstract: 1,185,075. Rotary-piston hydraulic pumps and motors. ROBERT BOSCH G. m.b. H. May 3, 1967 [May 6, 1966], No.20507/67. Heading F1F. A rotary-piston hydraulic pump, or motor, comprises a piston, or rotor, 4 with outwardlysliding vanes 8 that are lodged in slots 5 and engage with the peripheral wall 10 of a bore 9 containing chambers 11, 12 for the inlet and outlet of working fluid, each vane having a sharp edge 17 on the leading side thereof. While in a region α each vane has a force s exerted thereon by the working fluid, which force produces a turning moment about an edge 29 on the body of the rotor, this moment being balanced by one due a hydrodynamic force d created by fluid in a gap 27. The resultant force R 1  acts through the edge 29, thus preventing metal-to-metal contact between the wall 10 and the vane. When in a region # similar forces s<SP>1</SP>, d<SP>1</SP> act upon each vane, the resultant force R 2  pressing the vane against an edge 28 to prevent the contact aforesaid. The vane in being pressed against the edge 28, or 29, also prevents fluid flowing through the respective slot 5. Each vane is biased towards the wall 10 by a spring-loaded plunger 25.
