Variable displacement compressor method and apparatus

摘要

A variable displacement compressor includes an inclining swash plate connected to a drive shaft. A rotor rotates integrally with the drive shaft. A guiding mechanism is provided between the swash plate and the rotor to guide the inclination of tho swash plate between a minimum inclination position and a maximum inclination position and thus change the stroke of the piston. An abutment is provided to restrict the inclination of the swash plate. In another embodiment, a cap included in the guiding mechanism determines the maximum inclination position of the swash plate. In one embodiment, the maximum inclination position is determined by the length of a spring arranged between the swash plate and the rotor. In another embodiment, a spacer is arranged between the swash plate and the rotor. The thickness of the spacer determines the maximum inclination position. The maximum displacement of the compressor can be changed by changing only one part.
