OIL SEPARATOR FOR COMPRESSOR

An oil-separator (2) for an oil-lubricated compressor comprises a separator housing (40), a separator inlet (58) connectable to the compressor (1), a separator outlet and a separator chamber defined in the separator housing (40). The separator chamber is in fluid communication with the separator inlet (58) and the separator outlet. A hollow valve body (12) is located within the separator outlet and moveable between a first open position and a second closed position. A biasing member (14) biases the valve body (12) away from the second closed position. The valve body (12) has an open end (16) within the separator outlet, a closed end (18) located outside the separator outlet in the separator chamber, and at least one primary fluid aperture (22) extending through a wall of the valve body (12) so as to selectively permit fluid flow from the separator chamber into the separator outlet. The at least one primary fluid aperture (22) is at least partially exposed to the separator chamber when the valve body (12) is not in the second position. The valve body (12) has at least one secondary fluid aperture (24) extending through the closed end (18) such that the separator chamber is still in fluid communication with the separator outlet when the valve body (12) is in the second closed position.
