Abstract

1321485 Rotary positive-displacement machines ATLAS COPCO AB 18 June 1970 [18 June 1969] 5822/71 Divided out of 1321482 Heading F1F The subject-matter of this Specification is identical with that described in Specification 1321482, but the claims are concerned with a machine having single-toothed rotors, a gear transmission coupling the rotors to each other and a high-pressure port controlled by one of the rotors, which port is situated at one end of a bore containing this rotor and has an edge extending substantially along an arc of a circle co-axial with and equal in radius to the path described by the radially outer tip of the rotor tooth.
