ABSTRACT OF THE DISCLOSURE A wobble plate type compressor with a variable dis- placement mechanism includes a compressor housing which is provided with a crank chamber and a cylinder block in which a plurality of cylinders are formed. A drive shaft is rotatably supported in the compressor housing. A cam rotor is fixed on the drive shaft and variably connected to an inclined plate through a hinge mechanism. A wobble plate is adjacent the inclined plate. Cam rotor rotary motion is converted into wobble plate nutating motion. A plurality of pistons are coupled with the wobble plate each of which is reciprocably fitted within a respective one of the cylinders and of which the stroke volume is changed in accordance with variation of the angle of the inclined plate. The hinge mechanism includes a first arm portion extending from the cam rotor and having a hole formed therein and a guide pin fixedly disposed in the hole, and a second arm portion extending from the inclined plate. An elongated hole or slot is formed in the second arm portion. The guide pin cooperates with the elongated hole. The angle of the inclined plate can be rapidly changed to its maximum without using a return spring.
