Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
150 words
A valve comprising: a body; said body being in the form of a disc having opposed flat parallel inlet and outlet faces to facilitate slipping the body between a pair of flanges; said body having bolt holes formed therein to enable the body to be secured in place by the bolts of the flanges; a tilt disc for said body; a pivot shaft at one edge of said tilt disc, said body being formed with a flow port and being recessed (a) to provide a seat around said port for said tilt disc, (b) to accommodate said tilt disc, and (c) to accommodate said pivot shaft, whereby to pivotally support said tilt disc; and said pivot shaft extending outwardly sufficiently such that its ends are covered by the flanges between which the valve is mounted whereby said shaft is retained by said flanges in the recessed portion of said body.
Claim 2
Dependent Claim

A valve comprising: a body; said body being in the form of a disc having opposed flat parallel inlet and outlet faces to facilitate slipping the body between a pair of flanges; said body having bolt holes formed therein to enable the body to be secured in place by the bolts of the flanges; a tilt disc for said body; a pivot shaft at one edge of said tilt disc, said body being formed with a flow port and being recessed (a) to provide a seat around said port for said tilt disc, (b) to accommodate said tilt disc, and (c) to accommodate said pivot shaft, whereby to pivotally support said tilt disc; and said pivot shaft extending outwardly sufficiently such that its ends are covered by the flanges between which the valve is mounted whereby said shaft is retained by said flanges in the recessed portion of said body.
Claim 3
Dependent Claim
40 words
A valve as in claim 1 in which said shaft has its axis parallel to but offset from the plane of said tilt disc in a downstream direction to avoid bottoming out of said shaft when said tilt disc closes.
Claim 4
Dependent Claim
32 words
A valve as in claim 2 wherein said recessed portion is all in one plane and wherein the diameter of said pivot shaft is greater than the thickness of said tilt disc.
Claim 5
Dependent Claim
34 words
A valve as in claim 1 wherein said body has a generally pear-shaped port and said tilt disc is generally pear-shaped with the smaller end of the tilt disc attached to the pivot shaft.
Claim 6

A valve comprising: a body having a generally pear-shaped port having a narrower end; a generally pear-shaped tilt disc having a narrower end and adapted to cover said port; and pivot means mounting said tilt disc pivotally relative to said body about an axis adjacent the narroWer ends of said port and said disc.
Claim 9
Dependent Claim
54 words
A valve comprising: a body having a generally pear-shaped port having a narrower end; a generally pear-shaped tilt disc having a narrower end and adapted to cover said port; and pivot means mounting said tilt disc pivotally relative to said body about an axis adjacent the narroWer ends of said port and said disc.
Claim 10
Dependent Claim
29 words
A valve as in claim 7 wherein said pivot means includes a shaft portion integral with said disc and said body having a recess pivotally receiving the shaft portion.
Claim 11
