Abstract

PURPOSE:To enable operation with the least air supply ability matching the quantity of air consumed by a compressor by detecting a difference in pressures at a time in a loaded period and a time after a lapse of time (t) so as to compute the supply ability for the quantity of air used by the compressor. CONSTITUTION:A difference in pressures at a time t0 in a loaded period and a time t1 after a lapse of time (t) is a signal of informing whether an air supply ability of a motor is sufficient or short for a quantity of air to be consumed. Based on the difference in the pressures, if the quantity of the air consumed exceeds the supply ability thereat, the supply ability is enhanced so that the quantity of air supplied is pertinently corrected.
