Abstract
Abstract Means for preventing the radial collapse of a cylindrical portion of an expulsion bladder is secured to the bladder in such a way that the bladder can not be separated from the reinforcement in a normal direction by the application of actuation pressure but can be peeled away from the reinforcement by forces resulting from the actuation pressure.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
166 words
In a fluid storage and expulsion system having a pressure vessel and a collapsible expulsion bladder therewithin, said pressure vessel having an inlet for the application of actuation pressure to effect the collapse of said expulsion bladder, said expulsion bladder having a cylindrical portion which is collapsible in a longitudinal direction and in a radial direction, said expulsion bladder further having an inlet-outlet for the introduction of fluid into said bladder and for the expulsion of fluid therefrom during collapse thereof, the improvement comprising: reinforcing means for preventing radial collapse of said cylindrical bladder portion; and means for connecting said cylindrical bladder portion to said reinforcing means, said connecting means being sufficiently strong to resist separation of said bladder portion from said reinforcing means in a direction normal to said reinforcing means and bladder portion resulting from normal forces during the application of actuation pressure and insufficiently strong to resist peeling of said bladder portion from said reinforcing means during longitudinal collapse of said blAdder portion.
Claim 2
Dependent Claim
166 words
In a fluid storage and expulsion system having a pressure vessel and a collapsible expulsion bladder therewithin, said pressure vessel having an inlet for the application of actuation pressure to effect the collapse of said expulsion bladder, said expulsion bladder having a cylindrical portion which is collapsible in a longitudinal direction and in a radial direction, said expulsion bladder further having an inlet-outlet for the introduction of fluid into said bladder and for the expulsion of fluid therefrom during collapse thereof, the improvement comprising: reinforcing means for preventing radial collapse of said cylindrical bladder portion; and means for connecting said cylindrical bladder portion to said reinforcing means, said connecting means being sufficiently strong to resist separation of said bladder portion from said reinforcing means in a direction normal to said reinforcing means and bladder portion resulting from normal forces during the application of actuation pressure and insufficiently strong to resist peeling of said bladder portion from said reinforcing means during longitudinal collapse of said blAdder portion.
Claim 3
Dependent Claim
23 words
The fluid storage and expulsion system of claim 1, wherein said reinforcing means comprises a plurality of longitudinally extending circumferentially spaced reinforcing strips.
Claim 4
Dependent Claim
26 words
The fluid storage and expulsion system of claim 1, further comprising means for preventing substantial unequal collapse of said cylindrical bladder portion in a longitudinal direction.
Claim 5
Dependent Claim
28 words
The fluid storage and expulsion system of claim 3, wherein said last-mentioned means comprises a plurality of longitudinally spaced-apart circumferential rings on the interior of said bladder portion.
Claim 6
Dependent Claim
39 words
The fluid storage and expulsion system of claim 3, wherein said bladder has a central tubular portion, and said means for preventing substantial unequal collapse comprises a rigid member extending through said tubular portion in close fitting relation therewith.
Claim 7
Dependent Claim
29 words
The fluid storage and expulsion system of claim 1, wherein said reinforcing means comprises a plurality of circumferentially extending reinforcing rings in surrounding relation with said cylindrical bladder portion.
Claim 8
Dependent Claim
25 words
The fluid storage and expulsion system of claim 6, further comprising a plurality of longitudinally extending circumferentially spaced securement members connected to said reinforcing rings.
Claim 9
Dependent Claim
24 words
The fluid storage and expulsion system of claim 6, further comprising means for connecting said reinforcing means to the interior of said pressure vessel.
Claim 10
Dependent Claim
17 words
The fluid storage and expulsion system of claim 1, wherein said reinforcing means is said pressure vessel.
Claim 11
Dependent Claim
14 words
The fluid storage and expulsion system of claim 1, wherein said bladder is metallic.
Claim 12
Dependent Claim
37 words
The fluid storage and expulsion system of claim 10, wherein said bladder further comprises a substantially hemispherical head end and means thereon for rendering said bladder head end more resistant to uncontrolled buckling than to flexural yielding.
Claim 13
Dependent Claim
44 words
The fluid storage and expulsion system of claim 1, said bladder further comprising a head end including a piston with a central aperture therein, and a longitudinally extending member extending through said vessel and said piston aperture in close fitting relation with the latter.
