Abstract
Abstract A vessel is provided with a plurality of spaced-apart layers which contain fluid fill and closure means comprising a plurality of layers which are integrally formed with the layers of the pressure vessel. The fluid fill between the layers of the pressure vessel extends into and between closure layers, such that the fluid fill can be maintained under uniform pressure in each layer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
202 words
A pressure vessel adapted to be surrounded by at least one layer of fluid fill comprising an inner vessel wall defining an inner chamber open at one end for maintaining a fluid under pressure, at least one outer vessel wall, spaced apart from said inner vessel wall, defining at least one vessel channel adapted to contain said fluid fill, means for pressurizing said fluid fill in said vessel channel, said inner vessel wall including an inner closure and inner body section, with said inner closure being removably secured to said inner body section, said outer vessel wall including an outer closure and an outer body section, with said outer closure being removably secured to said outer body section, and external threads formed on said inner closure and said outer closure, and internal threads formed on said inner body section and said outer body section, such that said inner closure can be threadably engaged with said inner body section and said outer closure can be threadably engaged with said outer body section, whereby the displacement caused by said fluid fill under pressure to said inner vessel wall and outer vessel wall is substantially constant in situ of said inner closure and outer closure.
Claim 2
Dependent Claim
202 words
A pressure vessel adapted to be surrounded by at least one layer of fluid fill comprising an inner vessel wall defining an inner chamber open at one end for maintaining a fluid under pressure, at least one outer vessel wall, spaced apart from said inner vessel wall, defining at least one vessel channel adapted to contain said fluid fill, means for pressurizing said fluid fill in said vessel channel, said inner vessel wall including an inner closure and inner body section, with said inner closure being removably secured to said inner body section, said outer vessel wall including an outer closure and an outer body section, with said outer closure being removably secured to said outer body section, and external threads formed on said inner closure and said outer closure, and internal threads formed on said inner body section and said outer body section, such that said inner closure can be threadably engaged with said inner body section and said outer closure can be threadably engaged with said outer body section, whereby the displacement caused by said fluid fill under pressure to said inner vessel wall and outer vessel wall is substantially constant in situ of said inner closure and outer closure.
Claim 3
Dependent Claim
37 words
A pressure vessel according to claim 1 in which an inner gasket is positioned between said inner closure and inner body section, and an outer gasket is positioned between said outer closure and said outer body section.
Claim 4
Dependent Claim
267 words
A pressure vessel adapted to be surrounded by at least one layer of fluid fill comprising an inner vessel wall defining an inner chamber open at one end for maintaining a fluid under pressure, an intermediate vessel wall, spaced apart from said inner vessel wall, defining an inner vessel channel adapted to contain said fluid fill, an outer vessel wall, spaced apart from said intermediate vessel wall, defining an outer vessel channel adapted to contain said fluid fill, means for pressurizing said fluid fill in said inner vessel channel and said outer vessel channel, said inner vessel wall including an inner closure and inner body section, with said inner closure being removably secured to said inner body section, said intermediate vessel wall including an intermediate closure and intermediate body section, with said intermediate closure being removably secured to said intermediate body section said outer vessel wall including an outer closure and an outer body section, with said outer closure being removably secured to said outer body section, and external threads formed on said inner closure, intermediate closure and said outer closure, and internal threads formed on said inner body section, intermediate body section, and said outer body section, such that said inner closure can be threadably engaged with said inner body section, said intermediate closure can be threadably engaged with said intermediate body section, and said outer closure can be threadably engaged with said outer body section, whereby the displacement caused by said fluid fill under pressure to said inner vessel wall, intermediate vessel wall, and outer vessel wall is substantially constant in situ of the enclosures.
Claim 5
Dependent Claim
267 words
A pressure vessel adapted to be surrounded by at least one layer of fluid fill comprising an inner vessel wall defining an inner chamber open at one end for maintaining a fluid under pressure, an intermediate vessel wall, spaced apart from said inner vessel wall, defining an inner vessel channel adapted to contain said fluid fill, an outer vessel wall, spaced apart from said intermediate vessel wall, defining an outer vessel channel adapted to contain said fluid fill, means for pressurizing said fluid fill in said inner vessel channel and said outer vessel channel, said inner vessel wall including an inner closure and inner body section, with said inner closure being removably secured to said inner body section, said intermediate vessel wall including an intermediate closure and intermediate body section, with said intermediate closure being removably secured to said intermediate body section said outer vessel wall including an outer closure and an outer body section, with said outer closure being removably secured to said outer body section, and external threads formed on said inner closure, intermediate closure and said outer closure, and internal threads formed on said inner body section, intermediate body section, and said outer body section, such that said inner closure can be threadably engaged with said inner body section, said intermediate closure can be threadably engaged with said intermediate body section, and said outer closure can be threadably engaged with said outer body section, whereby the displacement caused by said fluid fill under pressure to said inner vessel wall, intermediate vessel wall, and outer vessel wall is substantially constant in situ of the enclosures.
Claim 6
Dependent Claim
50 words
A pressure vessel according to claim 1 in which an inner gasket is positioned between said inner closure and inner body section, an intermediate gasket is positioned between said intermediate closure and intermediate body section, and an outer gasket is positioned between said outer closure and said outer body section.
