Abstract
A gas regulator has a pressure control diaphragm biased by a spring. The force of the spring upon the diaphragm, and thus the operating pressure for the regulator, is controlled by a linear travel bushing bearing against the spring. The bushing is preferably threaded upon a shaft, the rotation of which allows travel of the bushing. The top end of the shaft is recessed within a bore in the regulator housing to deter tampering. The shaft may be locked in position by use of a recessed setscrew, while the access bore may be provided with a cover.
