Claims23
An apparatus for use in dispensing gas from a container containing gas under pressure comprising:
- an integrated combination of (A) a single stage demand vacuum breaker regulator, said regulator having an outlet for dispensing said gas and (B) a valve engaged thereto, said valve having a tubular inlet extending along a first axis for engagement with said container and a tubular outlet lying on said first axis,
- said vacuum breaker regulator having a body member with (i) a central passageway and an enlarged chamber lying on a second axis displaced from said first axis, said enlarged chamber having an outlet;
- (ii) a second chamber lying on said first axis and engaged by said valve tubular outlet for receiving gas therefrom, (iii) a passageway for delivering gas from said second chamber to said enlarged chamber, (iv) a poppet valve in said enlarged chamber for opening and sealing said outlet, said valve being yielding urged to a closed position, (v) a loading lever movable into and out of engagement with said poppet valve, (vi) a diaphragm movable toward said loading lever upon creation of a partial vacuum between said diaphragm and said loading lever and (vii) at least one cam lever movable between a position spaced from said loading lever to a position engaged to said loading lever upon movement of said diaphragm thereagainst.
An apparatus for use in dispensing gas from a container containing gas under pressure comprising:
- an integrated combination of (i) vacuum breaker regulator, said regulator having an outlet for dispensing said gas and (ii) a valve engaged thereto, said valve having a tubular inlet extending along a first axis for engagement with said container, an inlet to said vacuum breaker regulator lying on said first axis, a chamber and poppet valve communicating with said inlet and lying on a second axis spaced from said first axis and means for opening said poppet valve comprising a loading lever movable into and out of engagement with said poppet valve, a diaphragm movable toward said loading lever upon creation of a partial vacuum between said diaphragm and said loading lever and at least one cam lever movable between a position spaced from said loading lever to a position engaged to said loading lever upon movement of said diaphragm thereagainst.
An apparatus for use in dispensing gas from a container containing gas under pressure comprising:
- an integrated combination of (A) a single stage demand vacuum breaker regulator, said regulator having an outlet for dispensing said gas and (B) a valve engaged thereto and to said container;
- said vacuum breaker regulator having a body member with (i) a chamber lying on an axis, said chamber having an inlet for receiving gas from said valve and an outlet;
- (ii) a poppet valve in said chamber for opening and sealing said outlet, said poppet valve being yieldingly urged to a closed position, (iii) a loading lever movable to actuate said poppet valve, (iv) a diaphragm movable toward said loading lever upon creation of a partial vacuum between said diaphragm and said loading lever and (v) at least one cam lever movable between a position spaced from said loading lever to a position engaged to said loading lever upon movement of said diaphragm thereagainst.
An apparatus for using in dispensing gas from a container containing gas under pressure comprising:
- an integrated combination of (i) vacuum breaker regulator, said regulator having a chamber and an outlet for dispensing said gas and (ii) a valve engaged thereto and to said container, a passageway from said valve to said vacuum breaker regulator chamber, a poppet valve in said chamber movable between a first position closing said outlet to a second, open position permitting the flow of gas through said outlet, and means for moving said poppet valve from said first position to said second, open position including a loading lever movable to actuate said poppet valve, a diaphragm movable toward said loading lever upon creation of a partial vacuum between said diaphragm and said loading lever and at least one cam lever movable between a position spaced from said loading lever to a position engaged to said loading lever upon movement of said diaphragm thereagainst.
