Embodiment Construction

[0046] Such as figure 1 and 2 As shown, the valve as a whole is represented by reference numeral 1, and the valve includes: a valve body 2; a main cover 3, which is installed on one of the faces of the valve body 2; said one side. In the example shown, the valve 1 is defined along three axes, more specifically along a horizontal axis X, a transverse axis Y and a vertical axis Z.

[0047] The valve 1 is intended to be fitted between a storage tank 5 containing a gas of a first pressure, called "high pressure" such as a compressed Natural gas, compressed hydrogen or compressed oxygen. The first pressure is greater than the second pressure. The first pressure, called high pressure, is, by way of non-limiting example, between 100 and 700 bar, and the second pressure, called "low pressure", is between 5 and 20 bar. For example, the tank may be a tank designed to supply gas into a fuel cell.

[0048] By way of non-limiting example, the tank 5 has overall the shape of an altar ...

Abstract

Valve intended to be mounted on a tank containing a high-pressure gas. The valve body (2) incorporates a filling device (6) for filling the tank with high-pressure gas, at least one discharge device (9a) for discharging the gas when the pressure of the gas in the tank is above a first threshold value, a regulating device (7) for regulating the pressure of the high-pressure gas such that it becomes a low-pressure gas and a supply device (8) for supplying low-pressure gas to an apparatus that uses a low-pressure gas. The supply device (8) comprises an electrically operated valve (8a) controlling the supply of low-pressure gas to the apparatus that uses a low-pressure gas.

Description

technical field [0001] The invention relates to the field of storage tanks containing gaseous fuels at high pressure, such as compressed natural gas, oxygen or hydrogen. [0002] More specifically, the invention relates to a module installed in such a tank, which makes it possible both to supply the devices using the gaseous fuel contained in the tank and to fill the tank with gaseous fuel. [0003] A particularly advantageous application of the invention relates to a fuel tank of high-pressure gaseous fuel for supplying a fuel cell, for example a fuel cell in a motor vehicle. Background technique [0004] It has become increasingly common to use well-known alternative fuels such as propane or natural gas in internal combustion engines, or oxygen and hydrogen in electrochemical cells. These gaseous fuels can be stored in tanks at high pressure, the purpose of which is to store the maximum amount of fuel in the smallest volume possible. In the event of an accident, it must ...
