Abstract

1472291 Rotary positive displacement devices W C BLYTHING 24 Dec 1974 [8 Jan 1974] 00820/74 Heading F1F A rotary positive displacement device comprises a housing and two rotors which on adjacent faces have regularly spaced, radially extending teeth with one rotor having one more tooth than the other and the rotational axes of the rotors are inclined so that the spaces between the teeth vary cyclically. The outer surface defined by the two rotors is spherical and is engaged by the inner, similarly shaped surfaces of two (as shown) or more ring members 22, 23 which are apertured to allow fluidflow into and out of these spaces from and into inlet and outlet passages in the housing. As described, the ring member 23 has a series of apertures 28 with respective non return valves 29 which communicate via an arcuate port 27 in the casing with an inlet duct 25 and this ring is rotatable by a handle (not shown) to control fluid-flow into the teeth spaces. A similar arrangement is on the outlet side of the device in the ring member 22. Alternatively the apertures may be replaced by a respective slot in each ring member.
