A slant plate type compressor (10) with a capacity or displacement adjusting mechanism is disclosed. The compressor (10) includes a housing (20) having a cylinder block (21) provided with a plurality of cylinders 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 having a surface with an adjustable incline angle. The incline angle is controlled by the pressure in the crank chamber (22). The pressure in crank chamber (22) is controlled by control mechanism which comprises a passageway 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 and a second valve device (290) to control pressure in an actuating chamber (263). The first valve device includes a bellows valve element (193) and a valve shifting element (195). The valve shifting element (195) of which one end is exposed in the actuating chamber (263) is coupled to the bellows (193) to apply a force to the bellows (193) at another end and thereby shift a control point of the bellows in response changes in the actuating chamber pressure. |
