Abstract

The present invention includes: a valve main body including a filling port through which a fuel gas is filled in a tank and an output port through which the fuel gas in the tank is output; and a jet flow deflection piece through which the fuel gas to be filled through the filling port is ejected at a predetermined angle relative to an axial direction of the tank. The jet flow deflection piece includes: a fuel ejecting portion including an ejection port through which the fuel gas is ejected into the tank; and a temperature measuring portion in which a temperature sensor configured to measure a temperature of the fuel gas to be filled in the tank is provided. Thus, the temperature of the fuel gas when filling the fuel tank with the fuel gas can be precisely measure and monitored.

First claim

The invention claimed is:

1. A fuel tank valve comprising:
a valve main body including a filling port through which a fuel gas is filled in a tank and an output port through which the fuel gas in the tank is output; and
a jet flow deflection piece through which the fuel gas to be filled through the filling port is ejected at a predetermined angle relative to an axial direction of the tank, wherein
the jet flow deflection piece includes: a fuel ejecting portion including an ejection port through which the fuel gas is ejected into the tank; a temperature measuring portion in which a temperature sensor configured to measure a temperature of the fuel gas to be filled in the tank is provided; and an introducing passage through which a part of the fuel gas to he filled through the fuel ejecting portion is introduced into the temperature measuring portion.

2. The fuel tank valve according to claim 1 , wherein:
the jet flow deflection piece includes a bulkhead portion formed between the temperature measuring portion and the fuel ejecting portion; and
the introducing passage is provided at such a position that the fuel gas to be filled through the fuel ejecting portion does not directly hit the temperature sensor.

3. The fuel tank valve according to claim 1 , wherein the jet flow deflection piece includes the ejection port formed on a side surface of the jet flow deflection piece such that the fuel gas is ejected along an inner surface of the tank.

4. The fuel tank valve according to claim 3 , wherein the ejection port is formed such that the fuel gas is ejected in a direction rotated about a filling hole from a direction perpendicular to the axial direction of the tank by a predetermined angle in a circumferential direction, the filling hole communicating with the filling port.

5. The fuel tank valve according to claim 1 , wherein the jet flow deflection piece includes: an output hole that communicates with the output port; and a filter configured to remove foreign matters in the fuel gas to be output through the output hole to the output port.

6. The fuel tank valve according to claim 1 , wherein the valve main body includes a filter configured to remove foreign matters in the fuel gas to be output to the output port, the filter being provided on a surface of the valve main body, the surface being joined to the jet flow deflection piece.

7. The fuel tank valve according to claim 1 , wherein:
the valve main body includes a valve attaching portion to which an on-off valve provided inside the tank is attached; and
the jet flow deflection piece includes an opening portion that externally fits the on-off valve attached to the valve attaching portion.
