<p>PROBLEM TO BE SOLVED: To provide desired cooling performance at the starting time of a compressor. SOLUTION: This variable delivery compressor changes the inclination angle of a swash plate 5 according to a difference in pressure between a crank chamber 3 and a suction chamber 13 to change a piston stroke and control delivery capacity. A delivery chamber 14 and the crank chamber communicate with each other through a first communicating passage 18, so that the first communicating passage is controlled so as to be opened and closed by a pressure control valve 19. The crank chamber 3 and the suction chamber 13 communicate with each other through a second communicating passage 20. A valve element 21 is disposed at the second communicating passage 20. If a difference in pressure between the delivery chamber 14 and the suction chamber 13 is below a prescribed value, the valve element fully-closes the second communicating passage by the energizing force of a spring 22.</p> |
