Abstract
Abstract Two gas service regulators each having substantially the same size orifices, which orifices together meet the maximum volume required at the lowest inlet pressure, are connected together by a unitary valve body having outlet and inlet chambers each common to both regulators, each regulator having pressure-responsive means and a valve seat operated thereby, and said valve body having orifice tubes, one for each valve seat, to normally control the flow of gas from said inlet chamber to said outlet chamber, there being in said inlet chamber auxiliary valve means adapted to control the flow of gas from said inlet chamber to said orifice tubes in the event of malfunctioning of either regulator or of foreign matter being lodged between the valve seat and its orifice tube, said orifice tubes being axially slidable and axially aligned, said auxiliary valve means comprising said orifice tubes, and a coil spring interposed between said inlet chamber and said orifice tubes and being compressible to control the flow of gas through its coils to the extent of essentially stopping the flow of gas from said inlet chamber to said orifice tubes in the event of malfunctioning of the regulator or regulators.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
251 words
Gas pressure regulating means comprising two service regulators each having a housing, a cover therefor and diaphragm means secured therebetween and forming a service pressure chamber and an atmospheric pressure chamber; a unitary valve body forming a union between said regulators, said valve body having a dividing wall forming an inlet chamber adapted to be connected to an inlet line and an outlet chamber adapted to be connected to a service line, said outlet chamber being in direct communication with said pressure chambers of both said regulators, said valve body having two orifice means communicating with said inlet chamber and said outlet chamber, one of said orifice means being provided for each regulator; each said regulator having valve seat means and means connecting its diaphragm means to its valve seat means for operation thereof, said valve seat means cooperating with said orifice means to control the flow of gas therethrough to said outlet chamber, said orifice means collectively having such gas flow capacity as to supply the maximum volume required at the lowest inlet pressure, and said respective diaphragm means and valve seat means being adapted normally to function simultaneously and continuously to control the downstream pressure of said pressure regulating means, and auxiliary valve means in said valve body responsive to the outlet pressure of the gas adapted to regulate the flow of gas from said inlet chamber to said orifice means in the event either of said valve seat means or said orifice means fails to function as intended.
Claim 2
Dependent Claim
251 words
Gas pressure regulating means comprising two service regulators each having a housing, a cover therefor and diaphragm means secured therebetween and forming a service pressure chamber and an atmospheric pressure chamber; a unitary valve body forming a union between said regulators, said valve body having a dividing wall forming an inlet chamber adapted to be connected to an inlet line and an outlet chamber adapted to be connected to a service line, said outlet chamber being in direct communication with said pressure chambers of both said regulators, said valve body having two orifice means communicating with said inlet chamber and said outlet chamber, one of said orifice means being provided for each regulator; each said regulator having valve seat means and means connecting its diaphragm means to its valve seat means for operation thereof, said valve seat means cooperating with said orifice means to control the flow of gas therethrough to said outlet chamber, said orifice means collectively having such gas flow capacity as to supply the maximum volume required at the lowest inlet pressure, and said respective diaphragm means and valve seat means being adapted normally to function simultaneously and continuously to control the downstream pressure of said pressure regulating means, and auxiliary valve means in said valve body responsive to the outlet pressure of the gas adapted to regulate the flow of gas from said inlet chamber to said orifice means in the event either of said valve seat means or said orifice means fails to function as intended.
Claim 3
Dependent Claim
205 words
Gas pressure regulating means according to claim 1 in which said orifice means comprises two axially aligned orifice tubes mounted in said dividing wall in said valve body and axially slidable thereon; means for limiting the outward movement of said orifice tubes with the inner portions thereof axially spaced apart a determinate distance; said auxiliary valve means comprising a coil spring coaxial with said orifice tubes and engaging the inner ends of said tubes to normally hold the latter at the outer limits of their movements, said coil spring in expanded condition normally allowing gas to flow at a determinate rate from said inlet chamber through the spaces between its coils into said orifice tubes to said pressure chambers of the regulators, said coil spring being compressed to more or less close the spacEs between its coils to reduce the flow of gas to said orifice tubes and to said pressure chambers when the inner ends of said orifice tubes are brought more or less together and to stop such flow of gas when said spaces between said coils are closed by force applied to one or both of said orifice tubes by said valve seat means due to malfunctioning of either or both regulators.
Claim 4
Dependent Claim
38 words
Gas pressure regulating means according to claim 2 in which there are cooperating stop means on said orifice tubes and said dividing wall limiting the outward movement of said orifice tubes under the influence of said coil spring.
Claim 5
Dependent Claim
182 words
Gas pressure regulating means according to claim 1 in which said orifice means comprises two spaced axially aligned orifice tubes axially slidably mounted in said dividing wall, cooperating stop means on said orifice tubes and said dividing wall to limit the outward movement of said orifice tubes with their inner ends of said tubes normally spaced from each other sufficiently to permit the flow of gas from the inlet chamber to the outlet chamber of said housing to the maximum rate of flow desired, and said auxiliary valve means comprises spring means holding said orifice tubes at the limits of their outward movements and adapted to yield to permit the relative movement between the inner ends of the orifice tubes to more or less close and open the space between said inner ends to regulate the flow of gas from the inlet chamber to the outlet chamber if foreign matter interposed between the outer ends of either tube and the valve seat means prevents the latter from closing the orifice and causes the orifice tube to move inwardly of the dividing wall.
