Claims

[Claims for Utility Model Registration] 1. A swash plate disposed in the crank chamber is rotated by the rotation of the main shaft, and a oscillating plate that follows the inclined surface of the swash plate is oscillated to cause a plurality of pistons to reciprocate. The compressor is configured such that a rotor provided on the main shaft and the swash plate are supported by the rotor so that an inclination angle of the swash plate with respect to the main axis can be changed, and the rotation of the rotor is controlled by the rotor. a hinge mechanism for transmitting the signal to the swash plate; a slider connected to the swash plate and disposed so as to be slidable on the main shaft; and a force acting on the slider in the axial direction of the main shaft to move the slider. and an actuator for sliding in the axial direction to change the angle of inclination of the swash plate, and by adjusting the angle of inclination of the swash plate, the stroke amount of the piston is changed. A variable capacity compressor characterized in that the compression capacity is changed by changing the compression capacity. 2. Utility Model Registration Claim 1, wherein the actuator includes a communication chamber communicating with a discharge chamber, a plunger mechanism disposed in the communication chamber and linked to the slider via a thrust bearing, and a plunger mechanism communicating with the slider via a thrust bearing. and a valve mechanism for controlling the opening and closing of the chamber and the discharge chamber, the valve mechanism controls the opening and closing of the chamber, and the plunger mechanism is reciprocated by high pressure gas on the discharge side, thereby sliding the slider. A variable capacity compressor, characterized in that the angle of inclination of the swash plate is changed. 3 Utility Model Registration Scope of Claim 1 In the description of claim 1, the actuator includes a bellows mechanism linked to the slider via a thrust bearing, and a valve mechanism for controlling opening and closing of communication between the bellows mechanism and a discharge chamber. The bellows mechanism is controlled to open and close by controlling the opening and closing of the valve mechanism, and the bellows mechanism is expanded or contracted by high pressure gas on the discharge side, thereby sliding the slider and changing the inclination angle of the swash plate. A variable capacity compressor characterized by:
