<p>PROBLEM TO BE SOLVED: To provide a control device of a gas compressor capable of preventing deterioration of efficiency due to over-compression without increasing the volume of a main body.SOLUTION: A control device of a gas compressor for controlling the gas compressor having a rotor 23 rotatably arranged in a hollow portion of a cylinder member 24, a vane 25 attached to be freely projected or housed in the rotor and having an end slidably abutted to an inner peripheral surface of the hollow portion of the cylinder member so as to form a compression chamber, and a cylinder chamber 27 formed between the cylinder member and the rotor and performing a compression cycle of gas by changing the volume of the compression chamber includes: a motor 11 for driving the rotor; a speed and position calculator 14 for calculating a rotation speed and a rotation position of the rotor driven by the motor; and speed control sections 15-20 for reducing the rotation speed of the rotor to be lower than a prescribed rotation speed when the rotation position calculated by the speed and position calculator is within a range in which the inside of the compression chamber is at a delivery pressure or more.</p> |
