Abstract
Abstract A convertible fluid pressure regulator employing a flexible diaphragm valve operator and two springs, one of which biases the diaphragm at all times for regulating a fluid having a first pressure, such as natural gas, and the other of which additionally biases the diaphragm at selected times for regulating another fluid having a second, higher pressure, such as liquefied petroleum gas. A conversion member has a first position removeably seated in an opening in the regulator casing with a projection on the member acting on the second spring thereby to bias the diaphragm with additional force for regulating the higher pressure fluid. The conversion member also has a second, reversed position removeably seated in the casing opening with the projection disengaged from the second spring thereby rendering the same inactive so that the first spring alone biases the diaphragm for regulating the lower pressure fluid.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
211 words
In a convertible fluid pressure regulator for selectively regulating fluids at two different pressures and including a casing having a chamber therein and inlet and outlet ports communicating with said chamber, valve means for controlling fluid flow Between said ports, a flexible diaphragm in said casing and connected to said valve means for operating the same in response to pressure changes in said chamber, and a convertible spring loading assembly for said diaphragm comprising first spring means acting at all times on said diaphragm for biasing the same against the pressure exerted thereon with a first force thereby to regulate a first pressure, second spring means acting on said diaphragm at selected times for biasing the same against the pressure exerted thereon with an additional force thereby to regulate a second pressure higher than said first pressure, the improvement wherein said casing has an opening therein, said assembly further comprises a conversion member having a first position removeably seated in said casing opening with a portion of said member acting on said second spring means thereby biasing said diaphragm with said additional force, said conversion member having a second, reversed position removeably seated in said casing opening with said portion disengaged from said second spring means thereby rendering the same inactive.
Claim 2
Dependent Claim
211 words
In a convertible fluid pressure regulator for selectively regulating fluids at two different pressures and including a casing having a chamber therein and inlet and outlet ports communicating with said chamber, valve means for controlling fluid flow Between said ports, a flexible diaphragm in said casing and connected to said valve means for operating the same in response to pressure changes in said chamber, and a convertible spring loading assembly for said diaphragm comprising first spring means acting at all times on said diaphragm for biasing the same against the pressure exerted thereon with a first force thereby to regulate a first pressure, second spring means acting on said diaphragm at selected times for biasing the same against the pressure exerted thereon with an additional force thereby to regulate a second pressure higher than said first pressure, the improvement wherein said casing has an opening therein, said assembly further comprises a conversion member having a first position removeably seated in said casing opening with a portion of said member acting on said second spring means thereby biasing said diaphragm with said additional force, said conversion member having a second, reversed position removeably seated in said casing opening with said portion disengaged from said second spring means thereby rendering the same inactive.
Claim 3
Dependent Claim
45 words
The regulator of claim 1 wherein said conversion member portion comprises a projection thereon, said projection extending into said casing opening in said first position of said conversion member, said projection extending outwardly away from said casing in said second position of said conversion member.
Claim 4
Dependent Claim
38 words
The regulator of claim 2 wherein said projection comprises a plug member threadedly seated in an opening in said conversion member thereby to provide selective adjustment of said additional force in said first position of said conversion member.
Claim 5
Dependent Claim
36 words
The regulator of claim 3 wherein said plug member is secured in said conversion member opening thereby to apply the same predetermined additional force on said diaphragm whenever said conversion member is in said first position.
Claim 6
Dependent Claim
16 words
The regulator of claim 1 wherein said conversion member is threadedly seated in said casing opening.
Claim 7
Dependent Claim
45 words
The regulator of claim 1 wherein said assembly further comprises a spring seat member seated in said casing opening and acting on said first spring, said spring seat member having clearance therein for accommodating at least one said second spring means and conversion member portion.
Claim 8
Dependent Claim
26 words
The regulator of claim 6 wherein said spring seat member is threadedly seated in said casing opening thereby to provide selective adjustment of said first force.
Claim 9
Dependent Claim
26 words
The regulator of claim 7 wherein said spring seat member is secured in said casing opening thereby to apply a predetermined first force on said diaphragm.
Claim 10
Dependent Claim
143 words
The regulator of claim 1 wherein said first and second spring means are coil springs, said first spring surrounding said second spring, said assembly further comprising a spring seat member threadedly seated in said casing opening and acting on said first spring thereby to provide selective adjustment of said first force, said conversion member portion comprising a plug member threadedly seated in an opening in said conversion member thereby to provide selective adjustment of said additional force in said first position of said conversion member, said plug member extending into said casing opening in said first position of said conversion member and extending outwardly away from said casing in said second position thereof, said spring seat member having an opening therein for accommodating at least one of said second spring and plug member, said conversion member being threadedly seated in said casing opening.
Claim 11
Dependent Claim
56 words
The regulator of claim 9 wherein said plug member is secured in said conversion member opening thereby to apply the same predetermined additional force on said diaphragm whenever said conversion member is in said first position, said spring seat member being secured in said casing opening thereby to apply a predetermined first force on said diaphragm.
