PROBLEM TO BE SOLVED: To provide an air conditioning device capable of controlling troubles that a bellows and a valve rod follow flow of coolant to close a capacity control valve even if the capacity control valve is opened, and helping to reduce load on the compressor. SOLUTION: A main circuit of this device includes an accumulator 12, a compressor 13 and a heat exchanger. A bypass passage 3 returns excessive coolant from a compressor 13 to an accumulator 12 and includes a capacity control valve 4. The capacity control valve 4 is provided with a base body 41 including a valve chamber 40 having a coolant inlet 40a and a coolant outlet 40b, a movable valve rod 42 including a valve part 42c retained movably in a longitudinal direction of a valve chamber 40, a driving part 46 opening and closing the valve part 42c by moving the valve rod 42, a bellows 55 covering an outer peripheral surface of the valve rod 42 and sealing the valve chamber 40. The coolant outlet 40b is arranged to face on the outer peripheral surface of the valve rod 42 or the outer peripheral surface of the bellows 55. COPYRIGHT: (C)2004,JPO
