ABSTRACT:
A reciprocating piston type refrigerant compressor is disclosed. The compressor includes a housing having a cylinder block provided with a plurality of cylinders and a crank chamber adjacent the cylinder block. A piston slides within each cylinder and is reciprocated by a drive mechanism which includes a rotary drive shaft, a rotor mounted on the drive shaft, and a coupling mechanism which converts the rotary motion of the rotor into the reciprocating motion of the pistons. The coupling mechanism includes an inclined member which has an inclined surface disposed at an adjustable incline angle. Accordingly, the stroke of the pistons within the cylinders can be changed by adjusting the incline angle of the inclined surface in response to the change of pressure in the crank chamber. A spring applies a force to urge the inclined surface to a decreased incline angle when th incline angle is greater than a predetermined incline angle, but applies no force when the angle is less incline than the predetermined incline angle.
