Abstract

1419173 Rotary positive-displacement fluidmachines R W BRUNDAGE 10 July 1973 [31 July 1972] 4009/75 Divided out of 32938/73 1419171 Heading F1F The subject-matter of this Specification is identical with that described in Specification 1417171, but the claims are concerned with a machine havine a rotor, a rotary abutment member co- operating with the rotor, at least one lobe on the rotor, and a sealing member lodged in the or each lobe and biased towards the peripheral wall of a chamber for the rotor by fluid-pressure, the compartment on the trailing side of the or each rotor lobe being increased in volume and/or rendered in communication with an outlet passage prior to movement of the respective lobe past said passage.
