AIR SUPPLY CONTROL DEVICE FOR MAINTAINING PRESSURE OF OIL SUMP OF AIR COMPRESSOR

摘要

The present invention relates to an air supply control device for maintaining pressure of an oil sump of an air compressor. A bleed line supplying air generated by the air compressor to the oil sump is provided with a control valve to open or close the bleed line, and the control valve is operated by a control unit according to a load or an unload state of the air compressor. Since the bleed line is closed not to supply the air to the oil sump in an unload state in which the air compressor is stopped, it is possible to suppress the unnecessary supply of the air and thus reduce the energy consumption of the air compressor.;COPYRIGHT KIPO 2014
