Abstract
A gas dispensing assembly suitable for use in combination with an interchangeable high pressure gas supply vessel. The gas dispensing assembly includes a regulator means having a housing with a passageway and a check valve-gas flow regulator positioned in the housing passageway. The check valve is operable so as to block any gas flow above a predetermined pressure through the housing passageway from one end to the other end of the housing. The gas flow regulator controls the rate and/or pressure of the gas exiting from the regulator. The outlet demand valve has a housing with a passageway therethrough. Such housing is detachably connectable to the interchangeable high pressure gas supply vessel and to the other end of the regulator housing. A chamber is formed between such housing and the regulator housing. The height of the chamber is variable by adjusting the distance between both housings. An outlet demand valve is positioned in the housing passageway. The outlet demand valve is opened by an extended actuator, the end of which extends into the chamber. Actuator plate is movably located in the chamber. The actuator plate has at least one passageway therethrough which is not block…
