Abstract

Abstract A propellant augmented, pressurized gas dispensing device includes a high pressure gas chamber, a propellant chamber and a flow passage placing the two chambers in fluid communication. A valve is associated with the flow passage for allowing bidirectional flow between the chambers at differing flow rates. The valve allows relatively rapid flow from the propellant chamber into the gas chamber while restricting the flow from the gas chamber.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 88 words
A pressurized gas dispensing device including: , . means defining a first chamber for holding a gas under pressure; means defining a second chamber for holding a propellant; and means defining a flow passage placing said first and second chambers in fluid communication, characterised by: valve means associated with said flow passage for allowing bidirectional flow between said chambers at different flow rates, the flow rate from said second chamber to said first chamber being greater than the flow rate from said first chamber to said second chamber.
Claim 2
Dependent Claim 88 words
A pressurized gas dispensing device including: , . means defining a first chamber for holding a gas under pressure; means defining a second chamber for holding a propellant; and means defining a flow passage placing said first and second chambers in fluid communication, characterised by: valve means associated with said flow passage for allowing bidirectional flow between said chambers at different flow rates, the flow rate from said second chamber to said first chamber being greater than the flow rate from said first chamber to said second chamber.
Claim 3
Dependent Claim 100 words
The gas dispensing device of Claim 1 wherein the end of said passage adjacent said first chamber has an inlet opening communicating with said first chamber, characterised in that the valve means comprises: a seal member adapted to cover said inlet opening in sealing relationship, and means mounting said member for movement between a first position covering said opening and a second position spaced from said opening, said seal member having an opening therein aligned with said inlet opening when said seal member is in said first position, said opening in said seal member being smaller than said inlet opening.
Claim 4
Dependent Claim 37 words
The gas dispensing device of Claim 2 characterised in that the said seal member comprises: a flexible member, a portion of said flexible member being affixed to the wall of said second chamber adjacent said inlet opening.
