VARIABLE DISPLACEMENT COMPRESSOR

摘要

An axial piston, variable displacement, wobble plate gas or vapor compressor containing improvements in the capacity control system and in the drive plate and wobble plate mounting arrangements. A cam mechanism is driven by the drive shaft of the compressor, and at least one axially extending flange member is connected to the drive shaft. A lug is associated with a cam mechanism having a portion in spaced, juxtaposed relation with a surface on the flange, and a pivot link is attached at one end thereof to the flange and at the other end thereof to the lug. The lug is spaced from the axis of the drive shaft so that the cam mechanism is pivoted at a point not coincident with the drive shaft axis. No drive connection is provided at the drive shaft axis between the cam mechanism and the drive shaft, the link being positioned between the flange and the lug means so that the torque is transmitted from the drive shaft to the cam mechanism without producing a substantial bending moment on the pivot link.
