14. RIPTION The cooling system consists of a fan an oil air cooler separator element oil filter thermostatic valve interconnecting piping and tubing and sump tank The pressure in the air receiver sump causes oil flow by forcing the oil from the high pressure area of the sump to a lower pressure area in the compressor unit Oil flows from the bottom of the receiver sump to the thermostatic valve The thermostatic valve is fully open when the temperature is below 72 C Then the oil passes through the thermostatic valve the oil filter and directly to the compressor unit when it lubricates cools and seals the rotors and the compressor chamber As the discharge temperature rises above 72 C due to the heat of compression the thermostatic valve begins to close and a portion of the oil then flows through the cooler Oil flows from the cooler to main filter and then on to the compressor unit A portion of the oil flowing to the compressor is routed to the anti friction bearings which support the rotors in the compressor unit Prior to entering the compressor unit this oil is taken through oil filter thus assuring properly filtered lubricant for bearing supply The oil flow has three basic functions 1 As coolant it controls the rise of air temperature normally associated with the heat of compression 2 Seals the leakage paths between the rotors and the stator and also between the rotors themselves 3 Acts as a lubricating film between the rotors all
