ABSTRACT:
A slant plate type compressor with a capacity or displacement adjusting mechanism. The compressor includes a housing having a cylinder block provided with a plurality of cylinders and a crank chamber. A piston is slidably fitted within each of the cylinders and is reciprocated by a drive mechanism which includes a member having a surface with an adjustable incline angle. The incline angle is controlled by the pressure condition in the crank chamber. The pressure in the crank chamber is controlled by a control mechanism which comprises a passageway communicating between the crank chamber and a suction chamber, and valve to control the closing and opening of the passageway. The valve is disposed in a central bore which is formed in the cylinder block and supports one end of a drive shaft. A conduit extends from the central bore through the cylinder block and to the suction chamber.
