    • An outflow prevention device 5, 5a, 5b, 5c for preventing refrigerant from flowing out into a vehicle compartment when an evaporator 6 has ruptured comprises a shut valve 8 in a passage via which refrigerant introduced from an expansion device is allowed to flow to the evaporator 6, and a check valve 9 in a passage via which refrigerant returned from the evaporator 6 is allowed to flow to an accumulator 7. A chamber 22a behind a piston 22 fixed to a valve element 18 and a downstream side of the check valve 9 communicate via a bypass passage 35, so that differential pressure generated across the check valve 9 is applied to the shut valve 8 to open and close the same. The valve element 18 and the piston 22 have the same active diameters to prevent the shut valve 8 from influences of introduced pressure, enabling the shut valve 8 to operate only by the differential pressure generated across the check valve 9 (Fig.2).
    • 当蒸发器6破裂时,用于防止制冷剂流入车厢的流出防止装置5,5a,5b,5c包括在允许从膨胀装置引入的制冷剂流入蒸发器的通道中的截止阀8 在蒸发器6返回的制冷剂流过蓄能器7的通路中设有止回阀9。固定在阀体18的活塞22和止回阀9的下游侧的室22a相通 通过旁通通道35,使得跨止回阀9产生的压差被施加到截止阀8以打开和关闭。 阀元件18和活塞22具有相同的有效直径,以防止截止阀8受到引入压力的影响,使截止阀8只能通过止回阀9(图2)上产生的差压来操作。
