Abstract
A pressure indicator regulator assembly for a gas flow control device is disclosed for indicating the pressure of gas in a container. The pressure indicator regulator assembly includes a regulator housing integrally formed with a gas flow control device attached to a high pressure gas container. A tubular spiral coil pressure indicator is disposed within a recessed notch defined by the regulator housing and is in sealed fluid connection with the gas container through a stepped bore bushing disposed in a stepped bore passage. A cover having a transparent outer surface is removably attached to the housing at the notch, and forms a smooth, essentially continuous surface with respect to the exterior surface of the housing.
Claims17
A pressure indicator regulator assembly for a gas flow control device, the pressure indicator regulator assembly being positioned in sealed fluid connection between a gas inlet and a gas outlet respectively defined in the gas flow control device, the pressure indicator regulator assembly comprising:
- a regulator housing having an exterior surface and defining a gas inlet bore, a regulator cavity, a gas outlet bore, a recessed notch and a passage, said gas inlet bore capable of sealed fluid connection with the gas inlet, said regulator cavity disposed fluidly connecting said inlet bore and said outlet bore, said gas outlet bore capable of sealed fluid connection with the gas outlet, and said passage disposed fluidly connecting said inlet bore and said recessed notch;
- a pressure indicator disposed within said notch and in sealed fluid connection with said passage;
- a pressure indicator cover having a transparent surface formed to substantially correspond to said exterior surface proximate to said notch;
- and
- means for removably attaching said cover within said notch so that said transparent surface and said exterior surface form a generally smooth, continuous surface.
A pressure indicator regulator assembly for a gas flow control device, the pressure indicator regulator assembly being positioned in sealed fluid connection between a gas inlet and a gas outlet respectively defined in the gas flow control device, the pressure indicator regulator assembly comprising:
- a regulator housing having a generally cylindrical exterior surface and defining a gas inlet bore, a regulator cavity, a gas outlet bore, a recessed notch and a passage, said gas inlet bore capable of sealed fluid connection with the gas inlet, said regulator cavity disposed fluidly connecting said inlet bore and said outlet bore, said gas outlet bore capable of sealed fluid connection with the gas outlet, and said passage disposed fluidly connecting said inlet bore and said recessed notch;
- a pressure indicator disposed within said notch and in sealed fluid connection with said passage;
- a pressure indicator cover having a transparent outer surface formed as a portion of a cylindrical surface having radius substantially the same as the radius of said regulator housing, the dimensions of said cover chosen so that said cover is capable of engaging said notch with the axis defined by said outer surface coaxial with the axis defined by said regulator housing, said outer surface and the exterior of said regulator housing forming a generally smooth, continuous cylindrical surface;
- and
- means for removably attaching said cover within said notch.
A pressure indicator regulator assembly for a gas flow control device, the pressure indicator regulator assembly being positioned in sealed fluid connection between a gas inlet and a gas outlet respectively defined in the gas flow control device, the pressure indicator regulator assembly comprising:
- a generally cylindrical regulator housing defining a gas inlet bore, a regulator cavity, a gas outlet bore, a recessed notch and a passage, said gas inlet bore capable of sealed fluid connection with the gas inlet, said regulator cavity disposed fluidly connecting said inlet bore and said outlet bore, said gas outlet bore capable of sealed fluid connection with the gas outlet, said notch defining a partial disk-shaped volume formed by a generally planar rectangular rear surface, a generally planar arched first end surface and a generally planar arched second end surface, with said rear surface disposed generally parallel to the axis defined by said housing and said first and second end surfaces disposed adjacent to opposing edges of and normal to said rear surface, and said passage disposed fluidly connecting said inlet bore and said rear surface;
- a pressure indicator disposed within said notch and in sealed fluid connection with said passage;
- a partial disk-shaped pressure indicator cover having a transparent, rounded generally outer surface, a generally planar arched first side surface, and a generally planar arched second side surface, the radius of said outer surface substantially the same as the radius of said regulator housing, and said first and second side surfaces disposed adjacent to opposing edges and normal to the axis of said outer surface, the dimensions of said cover chosen so that said cover may engage said notch with the axis defined by said outer surface generally coaxial with the axis defined by said regulator housing, said first side surface disposed adjacent to said first end surface, and said second side surface disposed adjacent to said second end surface, said outer surface and the exterior of said regulator housing thereby forming a generally smooth, continuous cylindrical surface;
- and
- means for removably attaching said cover within said notch.
