Abstract: The fundamental function of a regulator is that of a variable orifice where, by automation, a determined set of pressure conditions can be automatically controlled with complete safety to the system and consumer. An example of the above statement was the result of an Indiana farm boys experience with gas pressure and a small valve. He was incubating eggs 24 hours a day using gas heat. In the day-time he would watch the gas flame and pinch or open the valve accordingly. However, at night the inlet pressure would build up and cook the eggs. Therefore, the mother of invention came to his rescue and we had a regulator manufacturer and the first house service regulator.

Mechanical linkage 4. Diaphragm 5, Counter balancing pressure means
