and two rotors.The compressor operates according to the rotary piston principle and is driven by anelectromotor through V-belts.  \nmain shaft  \nmale rotor  \noil injection  \nThere are two rotors with antifriction bearings in the housing:a male rotor with 5 lobesdriven by the motor and a female rotor with 6 voids.While the rotors are turning,air isdrawn in through the inlet port at the upper side of the housing and the trapped air iscompressed at the lower side.  \nThe oil injected into the housing at the lower side absorbs the heat produced by thecompression process,prevents the rotors from coming into contact and lubricates theantifriction bearings.  \nAs there are no unbalanced forces,inlet or outlet valves,smooth running of the unitis ensured.  \n# 3.DESIGN AND FUNCTION OF THE
