ABSTRACT:
A gas regulating valve includes a valve housing. A tubular valve member is received in the valve housing, defines a valve space, and is formed with a valve seat. The valve seat defines a valve opening, and divides the valve space into a gas feed portion and a gas supply portion. A valve stem is provided with a valve piece that extends into and that is axially movable relative to the valve member. Rotation of the valve stem results in corresponding rotation of the valve member and further results in translation of the valve piece. Translation of the valve piece toward and away from the valve opening enables the valve piece to respectively reduce and increase amount of gas flowing from the gas feed portion into the gas supply portion through the valve opening.
