A slant plate type compressor with a capacity or displacement adjusting mechanism is disclosed. 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 situation 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 a valve device to control the closing and opening of the passageway. The valve device includes a valve element which directly controls the closing and opening of the passageway. The valve device further includes a first bellows and a second bellows. The second bellows receives the discharge chamber pressure without an intrusion of the discharge chamber pressure into thepassageway, and is coupled to the first bellows to apply a force to the first bellows and thereby shift a control point of the first bellows in response to changes in the discharge chamber pressure.
