ABSTRACT:
A slant plate type compressor with a variable displacement mechanism includes a compressor housing having a cylinder block with a plurality of cylinders which are associated with a suction chamber. The compressor also comprises a crank chamber adjacent the cylinder block, a piston slidably received within each of the cylinders, and a drive mechanism coupled to the cylinders. The drive mechanism includes a drive shaft rotatably supported in the housing, a rotor coupled to the drive shaft and rotatable therewith, and a coupling mechanism for drivingly coupling the rotor to the pistons such that the rotary motion of the rotor is converted into reciprocating motion of the pistons. The coupling mechanism includes a member having a surface disposed at an incline angle relative to the drive shaft wherein the incline angle is adjustable to vary the stroke length of the pistons and the capacity of the compressor. The coupling mechanism also includes a hinge mechanism between the rotor and the incline member. The hinge mechanism includes a first arm portion extending from the rotor. The first arm portion includes a guide pin secured thereto for cooperation with a slot formed in a second arm portion extending from the incline member. The center of the guide pin is positioned between the center line of one of the cylinders and the center line of the drive shaft. The position of the guide pin permits rapid return of the inclined member to its maximum angular orientation in response to the difference between crank and suction chamber pressures without assistance for other mechanisms such as a return spring.
