초록

A variable oil flow regulator for minimizing noise generated typically by an oil-injected rotary screw compressor when the compressor transitions from an on-load mode for compressing fluid to an off-load mode. The regulator includes a housing having a first end, a second end and a chamber formed therein extending between the first and second ends. The regulator also includes a first port formed at the first end of the housing for admitting a pressure signal into the chamber corresponding to a compression level of the fluid, a second port formed at the se...
