<p><P>PROBLEM TO BE SOLVED: To avoid the deterioration of responsiveness of a control valve for discharging refrigerant to a suction pressure area from a control pressure chamber. <P>SOLUTION: A valve seat forming ring 54 is accommodated in a large diameter chamber 532 of a valve accommodation chamber 53. An end surface of the valve seat forming ring 54 can be bonded to a step difference 533 between a small diameter chamber 531 and the large diameter chamber 532. A valve element 55 is accommodated in the valve accommodation chamber 53 so as to pass through the inside of the valve seat forming ring 54, and formed of a first valve part 56 passing through the inside of the valve seat forming ring 54 to extend to a small diameter chamber 531 and a second valve part 57 fitted and fixed to the first valve part 56 in the large diameter chamber 532. The first valve part 56 is contacted to and separated from the bottom 591 having a valve hole 61 opened therein. The second valve part 57 is contacted to and separated from a valve seat forming ring 54. An annular clearance 58 encircling the second valve part 57 is provided between an outer peripheral surface of the second valve part 57 and inner peripheral surface 534 of the large diameter chamber 532. The valve hole 61, discharge chamber 59 and passage 62 constitute a discharge passage for discharging refrigerant to a suction chamber. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
