Patent ID: 7143782

Claim:
A pressure regulator module for controlling a gas, comprising: an enclosed chamber having at least one gas inlet and at least one gas outlet; a pressure sensor for measuring a gas pressure prevailing in the chamber; and a proportional valve operating according to the pressure-equalization principle, wherein the proportional valve is connected to the chamber and to the gas inlet, and wherein the proportional valve acts in concert with the pressure sensor; wherein the proportional valve includes a pot-shaped component formed as a stator and a pipe piece formed as a rotor, the pot-shaped component having radial openings which act together with radial outflow openings of the pipe piece; wherein the pipe piece is rotatable with respect to the pot-shaped component; wherein the pot-shaped component and the pipe piece concentrically positioned relative to one another; and wherein a separating wall is provided in the chamber, the separating wall dividing the chamber into an intermediate chamber portion associated with the proportional valve and an outflow chamber portion associated with the gas outlet.
