Claims

[Scope of utility model registration request]

In a compressor that is equipped with a variably controlled intake adjustment valve and is driven by an engine, a detector that detects the pressure value in the receiver tank and a rotation speed setting device that sets the engine rotation speed based on the detected value of the detector. a rotation speed control device that variably controls the engine rotation speed in response to commands from the rotation speed setting device; a detector that detects the engine rotation speed; and an intake capacity set based on the detected values of each of the above-mentioned detectors. Rotation/intake capacity of an engine compressor comprising an intake capacity setting device and a capacity control device that variably controls the opening degree of a throttle valve for adjusting the intake capacity based on a command from the intake capacity setting device. Electronic control unit.
