Abstract

PURPOSE: To minimize the energy required for positively raising the oil temperature by controlling the operation of a motor with a pressure switch and a humidity switch.
CONSTITUTION: When the pressure in a reservoir 8 reaches the predetermined valve, a pressure switch 20 act to open and the intake side of a compressor body 1 is communicated to an oil tank. Then the motor 2 and an air relief valve 19 act differently in response to the action of a humidity switch 21. In an other ward, when relative humidity of compressed air is high and drain is inclined to be generated, the humidity switch 21 is closed to continuously apply an electric current to the motor 2 while the air relief valve 19 is maintained closed. Consequently, the compressor body 1 compresses the pressurized air in an oil tank 6 and raises the oil temperature so as to minimize the energy for raising the oil temperature.
