<p>A refrigerant compressor (10) is disclosed which includes a compressor housing (20) which has a cylinder blook (21) which is provided with a plurality of cylinders, a front end plate (23) which is disposed on one end of the cylinder block (21) and encloses a crank chamber (22) within the cylinder block (21). A piston (71) is slidably fitted within each of the cylinders and reciprocated by a drive mechanism which includes a wobble plate (80), a rotor (40) connected to a drive shaft (26), an adjustable slant having an inclined surface in close proximity to the wobble plate (60) adjustably connected to the rotor (40) and has an adjustable slant angle. The slant angle changes in response to changes of pressure in the crank chamber (22) to change the capacity of the compressor. The front end plate (23) rotatably supportes the drive shaft (26) in a hole therethrough. A rear end plate (27) is disposed on the opposite end of the cylinder and a discharge chamber (251) therein. A control mechanism controls the opening and closing of a passageway (212) between the suction chamber (241) and the crank chamber (22). The control mechanism includes a first control valve which controls the opening and closing of one end of the passageway responsive to pressure in suction chamber (241) or crank chamber (22) and a second control valve mechanism which controls the opening and closing of the other end of the passageway (212) responsive to a pressure difference between the pressures in the suction and discharge chambers (241-251) whcih becomes equal or greater than a predetermined value. Therefore, the compressor can reduce torque shock very well.</p> |
