<p>A housing partitioning diaphragm type of gas pressure regulator for maintaining a different desired output pressure for different types of supply gas includes a threaded rod 7 extending into one of the housing chambers for establishing the force applied by a compression spring 8 to the diaphragm 2. To facilitate the adaptation of the regulator set pressure when changing from city gas to LPG, for example, abutment nuts 19, 22 or a flange 30 are provided on the rod intermediate its ends to determine preselected lengths by which the rod may be extended into the chamber. Thus, when changing from one type of gas to another, it is only necessary to remove, reverse, and reinsert the rod.</p> |
