Embodiment Construction

[0045] The embodiment of the invention shown is a regulator 30 for a refillable pressurized gas, particularly oxygen, container. Regulator 30 is used in a small refillable personal oxygen supply. When used with high pressure vessels, it can be used to hold more gas in a smaller space. The regulator is designed and tested to international safety and production standards and, importantly, designed to be operated with one hand.

[0046] The regulator 30 is used to regulate the high-pressure gas in the high-pressure container, and also has a filling valve and an over-pressure relief device, all of which are included in a light-weight and compact device. The regulator is also supplied with the various actuating mechanisms that operate the regulator to give the user a preference for interchangeable actuating mechanisms. The regulator 30 also has a number of tamper-resistant and tamper-resistant features.

[0047] Referring to the drawings in more detail, the regulator 30 is provi...

Abstract

An apparatus (60) for dispensing gas stored in a highly pressurized container (61) and then refilling the container (61) with more gas. The apparatus includes a regulator (30) that in turn includes a first valve assembly (5, 6, 7, 8) on a first gas flow path to permit the flow of gas from the container (61) into the regulator (30) and to maintain a substantially constant output gas pressure or speed, regardless of the internal pressure of the highly pressurized gas container (61). The regulator (30) also includes a second valve assembly (2, 13, 17, 18, 19) on a second gas flow path to refill the container (61) with highly pressurized gas and to seal the second gas flow path at times when the container (61) needs not be refilled. The over-pressure relief mechanism (9, 10, 11, 12) of the regulator (30) releases gas from the highly pressurized container (61) in response to a condition where the internal pressure of the container (61) exceeds one and two thirds of the maximum internal pressure of the container (61).

Description

[0001] Cross-references to related applications [0002] This application claims priority under 35 U.S.C. 119(e) (35 U.S.C. § 119(e)) to provisional application No. 60 / 540,740, filed January 30, 2004, and This provisional application is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to an apparatus for dispensing gas from a gas container and for refilling the gas container, and more particularly to an oxygen dispensing apparatus for dispensing gas consumption in a high pressure container and for refilling the container with consumed oxygen. Background technique [0004] In the manufacture of gas containers and gas distributors, a dispensing device or regulator must be provided to regulate the outflow of gas from the high pressure inside the container to the low pressure outside the container. The dispensing device or regulator must meet all relevant regulation requirements including safety requirements, whi...
