ABSTRACT:
A pressure regulating unit for providing two different controlled pressures includes a block made of a single piece of metal and having a mounting structure integrally provided thereon and a gas flow passage provided therein. A first regulator has a gas inlet communicating with a source of high-pressure gas having varying pressure and communicating with the gas flow passage. The first regulator is a step-down regulator for supplying a substantially constant pressure gas to second and third pressure regulators, enabling the second and third pressure regulators to be fixed at a predetermined, unmonitored pressure. At least the second and third regulators are supported on the mounting structure, and at least the second regulator has a gas inlet communicating with the flow passage. The second and third regulators provide the two pressures.
