<p>The gas flow regulator, for a gas burner, has a gas inflow (1) and outflow (10), and an auxiliary chamber (11) with a dividing wall to the inflow. A valve assembly (4-6) is operated by a membrane at the dividing wall through a pressure difference between the inflow and the chamber, to set the gas flow between the inflow and outflow. A servo pump (2) is at the dividing wall to act on the pressure difference by pumping gas from the chamber to the outflow. An overflow (3) gives a permanent fluid connection between the chamber and the inflow channel.</p> |
