A compressor system includes a lubricant reservoir, a screw compressor, and a valve. The screw compressor includes a housing defining a compression chamber having a suction port, a discharge port, a first lubricant feed port located between the suction port and the discharge port, and a second lubricant feed port located between the discharge port and the first lubricant feed port. The valve is in fluid communication with the lubricant reservoir, the first lubricant feed port via a first lubricant feed passageway, and the second lubricant feed port via a second lubricant feed passageway. The valve is movable between a first position and a second position. In the first position, the valve fluidly connects the lubricant reservoir to the first lubricant feed passageway to direct lubricant to the first lubricant feed port. In the second position, the valve fluidly connects the lubricant reservoir to the second lubricant feed passageway to direct lubricant to the second lubricant feed port.
A compressor system comprising:
A method of operating a compressor system, the compressor system including a lubricant reservoir adapted to contain a lubricant and a screw compressor, the screw compressor comprising a housing defining a compression chamber having a suction port, a discharge port, a first lubricant feed port located between the suction port and the discharge port, and a second lubricant feed port located between the discharge port and the first lubricant feed port, the method comprising:
