Abstract

The gas flow is regulated by a mechanism incorporating a gas inlet pipe connected to the pressure source of the gas, which is at virtually constant pressure and at a preset level, and leading to gas-and-air mixing chamber via a control tap. A ball valve opens and shuts the outlet pipe from the mixing chamber, allowing a vacuum produced in this pipe outside the chamber to suck the air/gas mixture from it. The tap can have a cylindrical housing with an outlet leading to the mixing chamber, and containing a rotary cylindrical plug with a wedge-shaped passage through it for the gas, so that gas flow is varied by altering the free cross-section of the passage.
