Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
163 words
A valve comprising a tubular body, means defining a first port at one end of said body, means defining a second port extending through sAid body, a plate extending across the interior of said body and positioned between said first and second port, a plurality of tubes extending from and in communication through said plate and in parallel relationship to each other and to the axis of said tubular body with each terminating in a separate annular valve seat, said valve seats being in substantially the same plane, a diaphragm mounted to move into and from engagement with said valve seats to close and open flow through said tubes, and a cover connected to the end of said body opposite said first port, said cover clamping the outer periphery of said diaphragm to said body, the center portion of said diaphragm being of substantially greater thickness than the remainder of said diaphragm and of sufficient diameter to engage all of said valve seats.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
31 words
A valve according to claim 1 including an annular shelf for supporting said diaphragm around said valve seats, said shelf slotted with slots sufficiently wide to allow solids to settle therethrough.
Claim 4
Dependent Claim
16 words
A valve according to claim 1 wherein said valve seat defining means defines seven valve seats.
Claim 5
Dependent Claim
16 words

Claim 7
Dependent Claim
26 words
A valve according to claim 1 wherein said central portion of said diaphragm is at least three times as thick as the remainder of said diaphragm.
Claim 8
Dependent Claim
28 words
A valve according to claim 1 wherein said central portion of said diaphragm has a thickness from one-third to one-fifth of the internal diameter of said valve seats.
Claim 9
Dependent Claim
34 words
A valve according to claim 1, wherein said diaphragm has a flexible annular portion immediately surrounding said central portion and an enlarged integral seal ring around the outer periphery of said flexible annular poriton.
Claim 10
Dependent Claim
18 words
A valve according to calim 1 wherein there are seven of said tubes positioned within said tubular body.
Claim 11
Dependent Claim
18 words
A valve according to calim 1 wherein there are seven of said tubes positioned within said tubular body.
Claim 12
Dependent Claim
18 words
A valve according to claim 1 wherein there are 19 of said tubes positioned within said tubular body.
Claim 13
Dependent Claim
33 words
A valve according to claim 1 wherein said diaphragm has a flexible annular portion immediately surrounding said central portion whereby said diaphragm may move freely into and from engagement with said valve seats.
