Abstract: An oil separator device includes at least a first chamber and a second chamber. An air-oil mixture may enter the body via the first chamber and may impact one or more interior surfaces within the body thereby causing at least a portion of the oil to be separated from the air-oil mixture. The separated oil may be directed to an oil reservoir and permitted to exit the body via an oil outlet. The remainder of the air-oil mixture may be directed toward the second chamber and be permitted to exit the body as working air via an outlet in communication with the second chamber. The oil separator device may include one or more baffles disposed between one or more of the first chamber, the second chamber, and the oil reservoir. A connector tube including one or more cylindrical members may facilitate communication between the first and second chambers.

Abstract: An oil flooded screw compressor includes a housing with an inlet and an outlet, and a rotor supported within the housing by a bearing. The rotor is rotatable to compress air from the inlet to the outlet when the compressor is in an operating state, and the rotor is rotatable without compressing air when the compressor is in an idle state. The compressor also includes a pump configured to supply oil to the bearing only when the compressor is in the idle state.
