ABSTRACT:
An air compressor is controlled such that when the pressure inside a tank for storing compressed air reaches a predetermined lower-limit value, the compressor is brought into a load running state to supply compressed air to the tank, whereas, when the pressure inside the tank reaches a predetermined upper-limit value, the compressor is brought into a stand-by state to suspend the supply of compressed air to the tank. The air compressor has a controller which judges the change in pressure inside the tank when the compressor is in a load running state on the basis of a signal delivered from a pressure sensor and effects control such that either one of two operations modes, that is, an intermittent operation mode in which the compressor stands by with the supply of electric power from a motor being cut off and a continuous operation mode in which the compressor stands by in a no-load state with the motor being supplied with electric power, is selected subsequent to a stand-by state. Thus, it is possible to obtain an air compressor having the advantages associated with both a pressure switch type control system and an automatic unloader type control system.
