Abstract

1365564 Rotary positive-displacement machines ATLAS COPCO A B 30 Sept 1971 [1 Oct 1970] 52930/73 Divided out of 1365563 Heading F1F The subject-matter of this Specification is identical with that described in Specification 1365563 (saving omission of details of the liquidinjection means) but the claims are concerned with a compressor having co-operating rotors, each rotor having a hub from which extends generally radially a tooth and wherein a recess is provided for the passage of the tooth of the other rotor, and the tooth of one rotor having a concave leading flank with a portion near the tooth root shaped to permit fluid trapped between the rotors to escape.
