TWIST COIL SPRING BIASED WOBBLE PLATE COMPRESSOR ABSTRACT OF THE DISCLOSURE A refrigerant compressor including a compressor housing hav- ing a cylinder block is disclosed. A plurality of cylinders are formed around the periphery of the cylinder block. A piston is slidably fitted within each of the cylinders and is reciprocated by a drive mecha- nism. A crank chamber is formed between the cylinder block and a front end plate of the compressor housing. The drive mechanism includes a drive shaft, a rotor disposed on the drive shaft, a slant plate with an adjustable slant angle disposed adjacent the rotor and a wobble plate disposed adjacent the slant plate. The drive shaft is rotatably supported within the front end plate. Rotation of the drive shaft causes rotation of the rotor and the slant plate, causing nutational motion of the wobble plate to reciprocate the pistons within their cylinders. The compressor housing includes a rear end plate defining suction and discharge. A communicating path commu- nicates between the crank chamber and the suction chamber. A stroke of pistons is changed by adjusting a slant angle of the slant plate. An elastic member urges the slant plate toward minimum slant angle to adjust the slant angle of the slant plate.
