ABSTRACT:
A body located downstream of the compressor discharge port in an oil-injected screw compressor assembly includes a contoured surface for directing the flow of the gas-oil mixture discharged from the compressor. The body is movable in the compressor assembly between a first position in which the flow of the mixture out of the discharge port is unimpeded and a second position in which the backflow of gas from downstream of the discharge port back into and through the working chamber of the compressor is prevented. In the first position the body facilitates the separation of oil from the discharged compressed gas while in the second position the reverse direction rotation of the screw rotors in the compressor working chamber is prevented. The body is positionable to the first position under the impetus of the mixture discharged from the compressor and is positionable to the second position under the impetus of the initial backflow of gas from downstream of the compressor, back to the compressor, which occurs upon compressor shutdown.
