Abstract

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.

First claim

What is claimed is:

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 a wiring port is formed in an outer circumferential surface of the casing through which the wiring is taken out to exterior of the casing, and the wiring port opens in a direction that is inclined with respect to an axial direction of the sensor.

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; 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 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 in an axial direction of the sensor including a measuring unit.

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 an axis of the sensor.
