  • Patent number: 6443502
    Abstract: A leakage restriction device for a refrigeration cycle of a vehicle air conditioner in which refrigerant flows has first and second rubber gaskets. The first and second gaskets are disposed between a pipe and a pipe joint of the refrigeration cycle for restricting refrigerant from leaking into atmospheric air. The first gasket is disposed on an atmospheric-air side and the second gasket is disposed on a refrigerant side between the pipe and the pipe joint. The first gasket has a gas permeability lower than that of the second gasket, and has a blistering-resistance which is inferior to that of the second gasket. As a result, refrigerant is restricted from leaking into atmospheric air, and a blister is restricted from being formed in the first and second gaskets even when a pressure of refrigerant is rapidly changed.
