Abstract

1443674 Rotary positive-displacement fluidmachines W MAYALL 13 Sept 1974 40009/74 Heading F1F In an hydraulic roller-vane motor, which is intended to drive a rock-drilling bit at the lower end of an oil well drilling string, the vanes 115 are forced radially outwards and against the leading sides of slots 116 by the pressure of the working fluid e.g. "mud", as they pass inlet ports 130. The pressure of the working fluid in the slots and on the trailing sides of the vanes between the ports 130 and exhaust ports 128 causes contra-rotation of a rotor 47 and inner and outer housing members 69, 51, the said members being fixed to each other. Recesses 127 direct the working fluid issuing from the ports 130 into the slots.
