Abstract
An oxygen pressure regulating device (100) is disclosed. The device (100) comprises a housing (102) including an inlet port (104) and an outlet port (106), the housing (102) including: a spring unit (112) including a plate (116) placed in fluid communication with the inlet port (104), the plate (116) being configured to be moved when impinged upon by an oxygen stream at a first pressure received through the inlet port (104); a bellows arrangement (118); and a switch (146) configured to be activated to open the outlet port (106) for releasing the oxygen stream through the outlet port (106). Also disclosed is a system comprising the oxygen pressure regulating device (100), a laminar flow element and a second conduit.

An oxygen pressure regulating device (100), comprising:
- a housing (102) including an inlet port (104) and an outlet port (106), the housing (102) including:
- a spring unit (112) including a plate (116) placed in fluid communication with the inlet port (104), the plate (116) directly facing an oxygen stream entering the inlet port (104) and being configured to be moved when impinged upon by the an oxygen stream at a first pressure received through the inlet port (104);
- a bellows arrangement (118) coupled to the spring unit (112) and biased with respect to the spring unit (112);
- a pin (140) coupled to the bellows arrangement (118), the pin (140) configured to move as the oxygen stream with the first pressure impinges on the plate (116) and moves the plate (116);
- and
- a switch (146) configured to be activated based on the movement of the pin (140) to open the outlet port (106) for releasing the oxygen stream through the outlet port (106), wherein the oxygen stream released through the outlet port (106) is released at a second pressure different from the first pressure when the first pressure overcomes a resistance offered by an assembly of the spring unit (112) and the bellows arrangement (118).
An oxygen pressure regulating device (100), comprising:
- a housing (102) including an inlet port (104) and an outlet port (106), the housing (102) including:
- a spring unit (112) including a plate (116) placed in fluid communication with the inlet port (104), the plate (116) being configured to be moved when impinged upon by the oxygen stream at a first pressure received through the inlet port (104);
- a bellows arrangement (118) coupled to the spring unit (112) and biased with respect to the spring unit (112);
- a pin (140) coupled to the bellows arrangement (118), the pin (140) configured to move as the oxygen stream with the first pressure impinges on the plate (116) and moves the plate (116);
- a second plate (130) coupled with the pin (140), wherein the second plate (130) is moveable along a pivot (134) in an axial direction (A) and is configured to contact a switch (146) upon the compression of the bellows arrangement (118);
- and
- the switch (146) configured to be activated based on the movement of the pin (140) to open the outlet port (106) for releasing the oxygen stream through the outlet port (106), wherein the oxygen stream released through the outlet port (106) is released at a second pressure different from the first pressure when the first pressure overcomes a resistance offered by an assembly of the spring unit (112) and the bellows arrangement (118).
