Abstract

1282613 Rotary positive-displacement machines E PRITCHARD 27 Oct 1969 [28 Oct 1968] 52543/69 Heading F1F A motor driven by a compressible fluid such as steam or air has a rotary structure 4 attached to an output shaft 21 and furnished with sealing segments 4a that engage with blades 3 supported by a fixed shaft 2. A proportion of the fluid in a supply line 6a is diverted through a flow-restricting passage 8 and a passage 9 into one of the interblade chambers 5 between an inlet port 6 and an outlet port 7. When it is necessary to augment the torque at the shaft 21 e.g. on starting, the flow through the passage 9 is increased by a valve 11 opening to connect a passage 10 to a passage 15, this being due to a greater pressure-differential occurring between the line 6a and a passage 13 and consequent deflection of a spring-loaded diaphragm 12. The effect produced by the increased flow through the passage 9 is comparable to that of "late cut-off" in a conventional reciprocating steam-engine. Alternatively, the valve may be such that it opens in response to a rise in the pressure in the line 6a, (For Figures see next page)
