A ROTARY POSITIVE DISPLACEMENT MACHINE Abstract of the Disclosure The invention concerns the formation of the high pressure port in a rotary, positive displacement ma- chine, such as a gas compressor, with an extension which is traversed by the plane on which the parallel axes of the rotors are commonly positioned. A given portion of the port extension is constantly occluded by the gating rotor and, consequently does not add to the effective area of the port. However, the remaining portion of the extension is exposed by the gating rotor, effectively defining a port opening which reaches to the common plane. Thus, in gas compressor use of the machine, the port extension insures that all the com- pressed gas product is delivered through the exhaust port.
