PURPOSE:To perform proper control by always accurately obtaining a stroke detection value by correcting the detection value of a stroke detection means by a correction means when the switching mode of a pressure switch is changed. CONSTITUTION:The variable capacity type compressor C connected to an internal combustion engine E has a plurality of differential pistons whose strokes are made variable. A stroke detection means 57 detects the operating stroke of an operation piston and a pressure switch 71 detects the emitting pressure corresponding to a stroke when the stroke of each differential piston is within a preset predetermined range. The detection value of the stroke detection means 57 is corrected by a correction means 72 when the switching mode of the pressure switch 71 is changed. When the stroke of the operation piston is within a preset range, the switching mode is changed by the pressure switch 71 to make it possible to correct the detection value of the stroke detection means 57 at that time to a set value. |
