ABSTRACT:
A swash plate of a variable displacement type compressor is swingably provided within a housing. Pistons reciprocate according to the swinging motion of the swash plate. The gas is compressed and discharged in response to the reciprocal motion of the pistons. As a stroke of the piston is varied according to the inclination angle of the swash plate, displacement of the compressor is varied. A displacement detector of the compressor includes a detected piece made of magnet. The detected piece is attached to one of the piston and a member which reciprocates in association with the piston. Detecting wires are arranged along the reciprocating locus of detected piece, and include a plurality of cyclic units which cross the center line extending in the longitudinal direction.
