Abstract
A compressor includes a plurality of pistons, a shaft and a wobble plate rotatably and swingably connected with said shaft so that the pistons are reciprocated in accordance with the wobbling movement of the wobble plate. The capacity of the compressor is varied in accordance with the inclining angle of the wobble plate. The actual capacity of the compressor is detected by the magnetic sensor. The compressor has a through member at the lower most portion of the pressure chamber provided in the housing and the slider is slidably connected with the through member. The slider also rotatably connected with the wobble plate so that the wobbling movement of the wobble plate makes the slider reciprocate along with the through member. Such movement of the slider is detected by the magnetic sensor.
