Recessed pressure indicator regulator assembly

摘要

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.
