摘要

A slant plate type compressor (10) with a capacity or displacement adjusting mechanism (400) is disclosed. The compressor (10) includes a housing (20) having a cylinder block (21) provided with a plurality of cylinders (70) and a crank chamber (22). A piston (71) is slidably fitted within each of the cylinders (70) and is reciprocated by a drive mechanism which includes a member (50) having a surface with an adjustable incline angle. The incline angle is controlled by the pressure in the crank chamber. The pressure in crank chamber (22) is controlled by a control mechanism (400) which comprises a passageway (150) communicating between the crank chamber (22) and a suction chamber (241), a first valve device (19) to control the closing and opening of the passageway (150) and a second valve device (39) to control pressue in an actuating chamber. The first valve device (19) includes a bellows valve element (195) and a valve shifting element (291) coupled to the bellows (193). The valve shifting elements (291) includes a first surface (293c) which receives pressure in the actuating chamber and a second surface which receives discharge pressure in order to apply a force to the bellows (193) at another end thereby shifts a control point of the bellows (193) in response to changes in the actuating chamber pressure and changes in the discharge pressure.
