Hinge mechanism for variable displacement compressors

U.S. Patent Number: 6474955

Abstract: variable displacement compressor has a drive shaft extending through a crank chamber. A lug plate is integrally fixed to the drive shaft. A drive plate is connected to and driven by the lug plate by a hinge mechanism. The drive plate inclines with respect to the drive shaft to vary the displacement of the compressor. The hinge mechanism has a linear guide on the lug plate and a pin projecting from the drive plate toward the lug plate. A bearing surface engages the pin. The pin has an axis that intersects an axis of the guide. The axis of the pin is parallel to the axis of the drive shaft when the compressor operates with a maximum load.
