Abstract:
A regulating element, said regulating element having a shaft, said shaft having a base plate attached to a bottom end of said shaft, a top end of said shaft, said top end having a regulating knob means, said regulating knob means consists of said top end having an externally threaded portion and a knurled portion located below said externally threaded portion, an indexing means, said indexing means being positioned perpendicular to a longitudinal axis of said shaft and extending outwards from said shaft;said regulating knob means further consists of a regulating knob having a first central hole, a horizontal plate, said horizontal plate bifurcating said first central hole creating a lower cavity and an upper recess, said horizontal plate having a second central hole connecting said lower cavity with said upper recess, said second central hole providing a tight frictional fit when said shaft of said regulating element penetrates therethrough allowing said externally threaded portion of said shaft to project beyond said horizontal plate, a measuring scale, said measuring scale being imprinted on an exterior surface of said regulating knob; a regulating curve, said regulating curve having a means for allowing said shaft of said regulating element to pass therethrough, said means for allowing said shaft to said regulating element to pass therethrough consists of a regulating curve with an externally threaded device, said regulating curve having a hole defined therein, said hole being centrally located to a longitudinal axis of said regulating curve allowing said shaft of said regulating element to pass therethrough; a lower surface of said regulating curve, said lower surface being spirally inclined providing an increasing downward slope, said lower surface additionally having means for positionally locating said indexing means in a fixed location when said indexing means is biased onto said lower surface of said regulating curve, said lower surface of said regulating curve further having a locating means, said locating means being a round nut, said round nut bearing against a pressure regulator housing and preventing any undesired motion of said regulating curve; means to prevent said regulating curve from being positionally dislocated in said pressure regulator housing; said means to prevent said regulating curve from being positionally dislocated in said pressure regulator housing consists of said round nut, said round nut being internally threaded with an upper surface and a lower surface, said round nut being threadably attached to said externally threaded surface of said regulating curve, said externally threaded surface of said regulating curve being threadably attached to said pressure regulator housing, said lower surface of said round nut bearing against a top surface of said regulator housing preventing said regulating curve from being positionally dislocated, said top surface of said round nut having means for a tool to rotate said round nut on said regulating curve; and said regulating knob means being attached to said shaft of said regulating element, a lock nut, said lock nut having a central internally threaded hole, said internally threaded hole threadably attached to said externally threaded top end of said shaft of said regulating element positionally locking said regulating element in a specified position in relation to said regulating curve and fitting within said upper recess, whereby when said regulating knob is rotated, said indexing means slides along said lower surface of said baseplate of said regulating element increasing compression on a biasing means bearing on a diaphragm located with said pressure regulator housing increasing or decreasing a flow of flammable gas through said regulator housing.
