Total Claims: 8
Claim 1
Independent Claim
159 words
A pressure relief assembly comprising: elongated support structure including means defining a bore therethrough of desired cross-sectional configuration, and flange means extending into said bore presenting a peripheral abutment face; bidirectional relief means for normally preventing fluid flow through said bore, and for bursting in the event of a pressure differential thereacross of preselected magnitude, said relief means including a frangible element having first inner unsupported line of weakness defining an inboard burst pattern and a second distinct, separately operable outboard line of weakness presenting an outboard burst pattern, said first burst pattern being located closer to the center of said element than said second burst pattern; and means for mounting said element across said bore in normal flow blocking relationship thereto, with the outer periphery of said element, and the entirety of said second outboard line of weakness defining the outer burst pattern being adjacent to and supported against movement in one direction by said flange abutment face.
Claim 2
Dependent Claim
159 words
A pressure relief assembly comprising: elongated support structure including means defining a bore therethrough of desired cross-sectional configuration, and flange means extending into said bore presenting a peripheral abutment face; bidirectional relief means for normally preventing fluid flow through said bore, and for bursting in the event of a pressure differential thereacross of preselected magnitude, said relief means including a frangible element having first inner unsupported line of weakness defining an inboard burst pattern and a second distinct, separately operable outboard line of weakness presenting an outboard burst pattern, said first burst pattern being located closer to the center of said element than said second burst pattern; and means for mounting said element across said bore in normal flow blocking relationship thereto, with the outer periphery of said element, and the entirety of said second outboard line of weakness defining the outer burst pattern being adjacent to and supported against movement in one direction by said flange abutment face.
Claim 3
Dependent Claim
24 words
The assembly as set forth in claim 1, said support structure comprising a pair of separate, interconnected, tubular support members cooperatively presenting said bore.
Claim 4
Dependent Claim
27 words
The assembly as set forth in claim 1, said support members each being generally circular in cross-section, and said outboard burst pattern being generally circular in plan.
Claim 5
Dependent Claim
41 words
The assembly as set forth in claim, said relief means including first and second, generally flat, opposed, rupture discs each having corresponding inboard and outboard burst patterns respectively, and a substantially imperforate, flexible membrane interposed between said first and second discs.
Claim 6
Dependent Claim
21 words
The assembly as set forth in claim 1, said inboard and outboard burst patterns comprising score lines formed in said element.
Claim 7
Dependent Claim
26 words
The assembly as set forth in claim 1, said inboard and outboard burst patterns comprising structure defining a plurality of elongated slots extending through said element.
Claim 8
Dependent Claim
86 words
The assembly as set forth in claim 1, said inboard burst pattern being configured for rupturing of said element in the event of a relatively high pressure differential across said element, which generates a force against the face of said element remote from said flange abutment face, said outboard burst pattern being configured for rupturing of said element in the event of a relatively low pressure differential across said element which generates a force against the face of said element proximal to said flange abutment face.
