    摘要： An air conditioning system (100) comprises a refrigerant circuit (40) and an electrical circuit (50). The refrigerant circuit (40) includes an indoor heat exchanger (23), an outdoor heat exchanger (13), a compressor (11), a refrigerant pipe (171), a first pressure stat (181), and a second pressure stat (182). The refrigerant pipe (171) is connected to the compressor (11) and forming at least part of the refrigerant circuit (40). The first pressure stat (181) is configured to detect pressure of the refrigerant in the refrigerant pipe (171). The second pressure stat (182) is configured to detect the pressure of the refrigerant in the refrigerant pipe (171). The electrical circuit (50) is configured to drive the refrigerant circuit (40). The first pressure stat (181) includes a first pressure sensor (630) and a first electrical switch (640). The first pressure sensor (630) has a first pressure threshold. The first electrical switch (640) is configured to stop the electrical circuit (50) from driving the refrigerant circuit (40) at least partially in accordance with the pressure detected by the first pressure sensor (630). The second pressure stat (182) includes a second pressure sensor (730) and a second electrical switch (740). The second pressure sensor (730) has a second pressure threshold. The second electrical switch (740) is configured to stop the electrical circuit (50) from driving the refrigerant circuit (40) at least partially in accordance with the pressure detected by the second pressure sensor (730). The first pressure threshold is different from the second pressure threshold.

    摘要： A bridge circuit (11) having four check valves (31, 32, 33, 34) is provided upstream of a receiver (10), which is provided upstream of an expansion valve (7). A gas vent pipe (12) for connecting the receiver (10) and a pipe (24) downstream of the expansion valve (7) to each other is provided, and the gas vent pipe (12) is provided with a gas vent valve (13). Upon shut down, the gas vent valve (13) is opened, and the expansion valve (7) is gradually closed. The compressor (4) is shut down and the gas vent valve (13) is closed after passage of a predetermined time from the point in time when the expansion valve (7) reaches the fully closed state.

    摘要： A leakage restriction device for a refrigeration cycle (10) of a vehicle air conditioner in which refrigerant flows has first and second rubber gaskets (4, 5). The first and second gaskets (4, 5) are disposed between a pipe (22, 23) and a pipe joint (20) of the refrigeration cycle (10) for restricting refrigerant from leaking into atmospheric air. The first gasket (4) is disposed on an atmospheric-air side and the second gasket (5) is disposed on a refrigerant side between the pipe (22, 23) and the pipe joint (20). The first gasket (4) has a gas permeability lower than that of the second gasket (5), and has a blistering-resistance which is inferior to that of the second gasket (5). 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 (4, 5) even when a pressure of refrigerant is rapidly changed.

    摘要： A body of a prior art thermal expansion valve is utilized as a valve body 30, and a rod member 316 of a heat sensing shaft 36f is a shaft with small diameter which is driven back and forth across a path 34 according to the displacement of a diaphragm 36a of a power element portion 36, so clearance 37, 38 is formed along the rod member 316 to connect the path 34 and the path 321. In order to seal the clearance, an x-ring 50 contacting the outer peripheral of the rod member 316 is positioned inside a large hole 38, so that the x-ring 50 exists between the two paths. Further, a push nut 41 working as a self-locking nut is mounted on the rod member 316 inside the large hole 38 contacting the x-ring 50 so as to prevent the x-ring from moving in the longitudinal direction (toward the power element portion 36) by the force from a coil spring 32d and the refrigerant pressure inside the path 321.
