<p>PURPOSE: To correctly regulate output efficiency by controlling a two port position-direction control valve with a regulator, and supplying piston stroke or angle of rotation of an oblique plate to the regulator as a regulating subject. CONSTITUTION: While a necessary cooling capacity for an air conditioner becomes high, a high temperature or a high output efficiency or a big piston stroke are supplied to a regulator 42 as the introduction data in the form of voltage. And, while an instant piston stroke is smaller than a piston stroke that is equivalent to a necessary output capacity, a second electromagnetic valve 39 is excited and is opened, so an oblique plate chamber 17 is connected to a suction chamber 21 through a second communication passage 37. Therefore, the pressure in the oblique plate chamber 17 becomes lower, and the pressure difference between the oblique plate chamber 17 and the suction chamber 21 becomes smaller. Further, the piston stroke increases, and output efficiency of the compressor is improved.</p> |
