Abstract
Abstract A flare fitting assembly is described comprising a pair of flare fittings, at least one of which is threadably fitted with a Schrader-type valve, and a separable Schrader-type valve actuating member. The valve actuating member is provided with a central receiving cup for releasably capturing the end of a valve stem extending from the valve. The actuating member serves to depress the valve stem and open the valve as the fittings are coupled together. The central receiving cup of the member serves to maintain the member axially aligned with respect to the axis of the fittings and releasably retain the member on the stem when the fittings are decoupled.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A flare fitting assembly comprising: a first flare fitting; a second flare fitting; a resiliently biased valve having a movable valve stem with a free end axially disposed in one of said flare fittings; a means for coupling together said first and said second flare fittings; a means removably coupled to said free end of said valve stem for actuating said valve when said first and said second flare fittings are coupled together wherein said valve actuating means comprises a cup-shaped extension for removably receiving said free end of said valve stem and further comprising: a passageway adjacent said cup-shaped extension for providing fluid and gas communication through said valve actuating means wherein said cup-shaped extension is formed for releasably capturing said free end of said movable valve stem for retaining said valve actuating means on said movable stem when said first and said second flare fittings are decoupled.
Claim 2
Dependent Claim
149 words
A flare fitting assembly comprising: a first flare fitting; a second flare fitting; a resiliently biased valve having a movable valve stem with a free end axially disposed in one of said flare fittings; a means for coupling together said first and said second flare fittings; a means removably coupled to said free end of said valve stem for actuating said valve when said first and said second flare fittings are coupled together wherein said valve actuating means comprises a cup-shaped extension for removably receiving said free end of said valve stem and further comprising: a passageway adjacent said cup-shaped extension for providing fluid and gas communication through said valve actuating means wherein said cup-shaped extension is formed for releasably capturing said free end of said movable valve stem for retaining said valve actuating means on said movable stem when said first and said second flare fittings are decoupled.
Claim 3
Dependent Claim
84 words
A fitting assembly according to claim 1 wherein one of said first and said second flare fittings is provided with a beveled convex surface and the other of said flare fittings is provided with a corresponding flared concave surface, said valve actuating means is provided with a concave surface corresponding to said beveled surface and a convex surface corresponding to said flared surface and wherein said cup-shaped extension extends from at least one of said concave and convex surfaces of said valve actuating means.
Claim 4
Dependent Claim
72 words
For use in actuating a valve threadably engaged in a flare fitting, with said valve as an integral part thereof, a valve actuating member comprising: an annular member having a fluid passageway therethrough; and a cup-shaped receptical axially disposed in the interior of said annular member for removably receiving said valve stem, said cup-shaped receptacle being formed to capture said valve stem for removably retaining said annular member on said valve stem.
Claim 5
Dependent Claim
72 words
For use in actuating a valve threadably engaged in a flare fitting, with said valve as an integral part thereof, a valve actuating member comprising: an annular member having a fluid passageway therethrough; and a cup-shaped receptical axially disposed in the interior of said annular member for removably receiving said valve stem, said cup-shaped receptacle being formed to capture said valve stem for removably retaining said annular member on said valve stem.
