A compressor and oil separator assembly for compressing a fluid includes a suction end, a discharge end, and first and second rotors rotatably mounted between the suction and discharge ends. A discharge line communicates with the discharge end, and an oil separator communicates with the discharge line. An oil sump communicates with the oil separator and an oil supply line communicates between the oil sump and the rotors. A bleed line selectively communicates between the discharge line and the oil supply line for equalizing a pressure differential between the suction end and the discharge end without causing substantial backward rotation of the rotors or displacement of oil to the rotors through the oil supply line. Preferably, the assembly further includes a valve that defines a portion of the discharge line and is also coupled to the bleed line.

1. A temperature control system comprising:a condenser; an evaporator; a compressor coupled between the evaporator and the condenser for compressing a refrigerant circulating through the temperature control system, the compressor having a set of rotors in a compression chamber, a discharge end, and a suction end; an oil separator communicating with the discharge end via a discharge line; an oil sump communicating with the oil separator; an oil supply line communicating between the oil sump and the compression chamber; and a bleed line selectively communicating between the discharge line and the oil supply line for equalizing a pressure differential across the compressor without causing substantial backward rotation of the rotors or displacement of oil to the compression chamber through the oil supply line.
