Abstract

1301528 Rotary pumps and motors DANFOSS A S 1 June 1970 [19 June 1969] 26219/70 Heading F1F A rotary pump or motor of the kind in which an externally-toothed wheel 15, Fig.2, is placed inside an internally-toothed ring 4 having one more tooth and in which one of the members, as shown the internally-toothed ring 4 is provided with a plurality of spaced recesses 19 in each of which is a roller-vane 16 constituting the teeth of the ring 4, the roller-vanes are bearingly supported in end plates (3, 5) to provide a clearance between each roller and its recess which is sealed by a self-adjusting sealing element 21 slidable in a slot 22 extending over the full width of the wheel 15 and ring 4 to seal adjacent variable volume chambers from each other. This arrangement reduced friction and hence wear between the roller vanes and the ring 4. The sealing elements may be of case-hardened steel and, urged into engagement with the rollers by leaf-springs (23) or the pressure at the high pressure side of the pump or motor communicated to spaces (24) beneath the sealing elements. A commulator valve (35) driven at the same speed as the ring 4 to supply and exhaust hydraulic fluid to and from the variable volume chambers 20 includes annular grooves (42, 43) inter-connected by annular grooves (39, 41) in an end cover plate (8) to pressure balance the valve (35) axially.
