ABSTRACT:
A self-operated droop compensated regulator includes a spring casing and a lower casing, sandwiching a diaphragm. The lower casing has axially aligned inlet and outlet ports. A one piece cam stem and relief seat is mounted for movement with the diaphragm and includes a first cam surface for directly engaging a movable disk holder. The disk holder is movable in a straight line within an orifice tube that supports the valve seat. The cam surface moves the disk holder at a nonlinear rate with respect to the diaphragm. The orifice tube has an extension for providing a boost action to the diaphragm. A pressure relief mechanism is incorporated within the upper portion of the diaphragm. A bias spring acts, between a second similar cam surface on the opposite side of the stem and the disk holder, to maintain the first cam surface in contact with the disk holder.
