Abstract

A pressure reducing valve device of the type comprising a valve, an expansion chamber disposed downstream of the valve relative to the gas outlet pipe, at least one wall of this chamber being formed by a flexible and displaceable membrane, the membrane being connected to the valve member in such a way that a rise in the pressure of the expansion chamber tends to cause the valve to close, characterized in that an auxiliary transfer chamber comprising at least one movable wall element is arranged in a gas circuit between the valve and the expansion chamber, the two chambers being connected by a pressure drop communication, said wall element being connected to the valve member, causing pressure drop created by said communication a pressure differential that constantly exerts on the valve member an auxiliary opening force, proportional to the discharge discharge that passes through it.
