Abstract

1419172 Rotary positive-displacement fluidmachines R W BRUNDAGE 10 July 1973 [31 July 1972] 4007/75 Divided out of 32938/73 1419171 Heading F1F The subject-matter of this Specification is identical with that described in Specification 1419171, but the claims are concerned with a machine having a rotor, a rotary abutment member co-operating with the rotor, a bearing sleeve for a shaft portion of said member, and an annular seal between said sleeve and a portion of a housing wall defining an opening into which the shaft portion extends.
