Abstract (en)

Variable displacement compressor may include a swash plate (8). The inclination angle of the swash plate can be changed to change the compressor output discharge capacity. A rotor (7) is coupled to the drive shaft so that the rotor rotates together with the drive shaft. A hinge mechanism (20) connects the swash plate with the rotor by means of a guide on a rotary disk of the rotor. The rotor preferably includes a set of functional parts defined by a rotary disk (22), a guide (23) disposed on the rotary disk and a weight (24) disposed on the rotary disk to adjust the weight balance of the rotor. At least one of the functional parts is formed by pressing and punching a metal plate. In addition or in the alternative, two or more of the functional parts may be integrally and seamlessly manufactured by pressing and punching a metal plate.
