<p>PURPOSE:To moderate increase of load torque in a clutchless compressor. CONSTITUTION:When an inclination angle of a swash plate 15 supported on a rotary shaft 9 is getting closer to the minimum inclination angle, the swash plate body 15 pushes a transmission cylinder 28 and a throttle body 21 against spring force of a suction passage release spring 24. The throttle body 21 is applied to a positioning surface 27 when the swash plate inclination angle is the minimum inclination angle to disconnect communication of a suction passage 26 with a suction chamber 3a. When the swash plate inclination angle is the maximum, a crank chamber 2a and the suction chamber 3a are communicated with each other through a route of a passage 30, the inside of the cylinder of the throttle body 21, and a relief port 21c, and a route of the passage 30, the inside of the cylinder of the throttle body 21, a connection passage 21d, and a passage 14. When the swash plate inclination angle is the minumum, the crank chamber 21 and the suction chamber 3a are communicated with each other through the route of the passage 30, the inside of the cylinder of the throttle body 21, and the relief port 21c.</p> |
