ABSTRACT:
A slant plate type compressor with capacity adjusting mechanism is disclosed. The compressor housing has a cylinder block provided with a plurality of cylinders and a piston slides within each cylinder. The piston is reciprocated by a swash plate driven by a drive shaft through a hinge coupling mechanism which includes a mechanism for changing the slant angle of the swash plate. The swash plate is supported for nutational (wobbling) and rotational motion on the drive shaft through a spherical bush and is operatively connected to the pistons through bearing shoes. Accordingly, each piston accomplishes reciprocating movement within a cylinder by the rotation of the swash plate and the stroke of piston is changed by the hinge coupling mechanism due to a pressure difference between the crank chamber and the suction chamber.
