In an in-tank valve, a detector including a detecting sensor is disposed on an end of a body, and the detecting sensor is accommodated inside a sensor housing. Within the sensor housing, a sensor retaining member is formed in an interior part of an opened sensor accommodating section, and the detecting sensor is disposed therein so as to face toward a first communication hole of the sensor retaining member. Lead wires, which are connected to the detecting sensor, are led out to the exterior in a bending fashion from a wiring port, whereby entry of hydrogen gas to the side of the detecting sensor is prevented by suitably closing the wiring port.
1. An in-tank valve disposed in a tank in which a high pressure gas is stored in interior thereof, and including in the interior of the tank a detector configured to detect a temperature of the high pressure gas, the detector comprising:
a sensor configured to detect the temperature;
wiring connected to the sensor; and
a casing including a fixing member configured to fix the sensor in interior of the casing, at least part of the wiring being accommodated in the casing;
wherein an outer circumferential surface of the casing includes a wiring port through which the wiring is taken out to exterior of the casing, and a flat portion extending along an axial direction of the casing and positioned on an inner side of an outermost circumferential surface of the casing,
the wiring port opens in a direction that is inclined with respect to the axial direction of the casing, and the wiring port is defined by chamfered walls.
2. An in-tank valve disposed in a tank in which a high pressure gas is stored in interior thereof, and including a detector configured to detect a temperature of the high pressure gas, the detector comprising:
a sensor configured to detect the temperature;
wiring connected to the sensor;
a casing including a fixing member configured to fix the sensor in interior of the casing, at least part of the wiring being accommodated in the casing; and
a flat portion extending along an axial direction of the casing,
wherein the flat portion is positioned on an inner side of an outermost circumferential surface of the casing,
the casing includes a wiring port defined by chamfered walls,
an interior space of the casing includes a sensor space section in which the sensor is arranged, the sensor space section being defined by the fixing member; and
the fixing member comprises at least one communication hole configured to allow communication between the sensor space section and the interior of the tank.
3. The in-tank valve according to claim 2 , wherein the communication hole is arranged in facing relation to one end of the sensor including a measuring unit in the axial direction of the casing.
4. The in-tank valve according to claim 2 , wherein the communication hole is arranged in facing relation to a side wall that is substantially perpendicular to the axial direction of the casing.
