Kind Code:
A1
Abstract:
The present invention relates to a control device for controlling the operation of a compressor, an electronic control valve used for the same, and a compressor comprising the same. Provided is a control device of a compressor, comprising: a piston which reciprocates by a swash plate; a crankcase for accommodating the swash plate, wherein the swash plate is mounted such that the inclination angle thereof with respect to a rotational shaft is variable; a discharge chamber from which a compressed working fluid is discharged; a suction chamber for suctioning a working fluid to be compressed; a first communication channel for connecting the suction chamber and the crankcase; a second communication channel for connecting the discharge chamber and the crankcase; and a control valve for selectively opening and closing the first and second communication channels, the control device of the compressor further comprising: a suction pressure sensor for measuring the pressure of the suction chamber; a valve control unit for determining a target suction pressure on the basis of a value measured by the suction pressure sensor and a preset temperature; and a valve operation unit for controlling the opening of the control valve to achieve the target suction pressure determined by the valve control unit.
