Abstract
Abstract A reinforced valve member including a body having upstream and downstream sides and an annular rim forming a first sealing surface. A frusto-conical portion of the body extends upstream from the first sealing surface and displays a second sealing surface. A substantially conical flow diverter extends upstream from the frusto-conical portion and a plurality of guide fins extend upstream from the flow diverter. The annular rim, frusto-conical portion and flow diverter are all coaxially aligned on the longitudinal axis of translation of the valve member. A dish-shaped reinforcing washer is embedded in the valve member body and includes a concave side oriented upstream and a convex side oriented downstream.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
78 words
A reinforced mud pump valve member, which comprises: (a) a body including: (1) an upstream side; (2) a downstream side; (3) a flat annular rim terminating upstream at a first flat, annular sealing surface; and (4) a frusto-conical portion extending upstream from said first sealing surface and having a bevelled second sealing surface; and (b) a dish-shaped reinforcing washer convex toward said upstream side and concave toward said downstream side and entirely embedded within said valve member body.
Claim 2
Dependent Claim
78 words
A reinforced mud pump valve member, which comprises: (a) a body including: (1) an upstream side; (2) a downstream side; (3) a flat annular rim terminating upstream at a first flat, annular sealing surface; and (4) a frusto-conical portion extending upstream from said first sealing surface and having a bevelled second sealing surface; and (b) a dish-shaped reinforcing washer convex toward said upstream side and concave toward said downstream side and entirely embedded within said valve member body.
Claim 3
Dependent Claim
20 words
The valve member according to claim 1 which includes: (a) said reinforcing washer being coaxial with said valve member body.
Claim 4
Dependent Claim
34 words
The valve member according to claim 1 which includes: (a) a substantially conical flow diverter extending upstream from said frusto-conical portion; (b) said annular rim, said frusto-conical portion and said flow diverter being coaxial.
Claim 5
Dependent Claim
43 words
The valve member according to claim 3 which includes: (a) said frusto-conical portion of said body forming a first base angle; and (b) said flow diverter forming a second base angle; (c) said first base angle being greater than said second base angle.
Claim 6
Dependent Claim
17 words
The valve member according to claim 4 which includes: (a) guide means extending from said flow diverter.
Claim 7
Dependent Claim
30 words
The valve member according to claim 5 wherein: (a) said guide means comprises a plurality of spaced guide fins extending radially from a longitudinal translational axis of said body member.
Claim 8
Dependent Claim
15 words
The valve member according to claim 1 which includes: (a) said reinforcing washer comprising metal.
Claim 9
Dependent Claim
17 words
The valve member according to claim 7 which includes: (a) said reinforcing washer having a rough-textured surface.
Claim 10
Dependent Claim
45 words
The valve member according to claim 7 which includes: (a) a plurality of apertures extending through said reinforcing washer, said apertures being adapted to receive said material comprising said body whereby portions of said body on either side of said reinforcing washer are bonded together.
Claim 11
Dependent Claim
22 words
The valve member according to claim 7 which includes: (a) said body material being polymeric; and (b) said body being unitarily formed.
Claim 12
Dependent Claim
44 words
The valve member according to claim 7 which includes: (a) an opening from said valve member upstream side to said reinforcing washer, said opening being adapted to receive a mechanical positioner for positioning said reinforcing washer in said body when said body is formed.
Claim 13
Dependent Claim
162 words
A reinforced mud pump valve member, which comprises: (a) a body which includes: (1) an upstream side; (2) a downstream side; (3) an annular rim having a first sealing surface; (4) a frusto-conical portion extending upstream from said first sealing surface and having a second sealing surface; (5) a substantially conical flow diverter extending upstream from said frusto-conical portion; (6) a plurality of spaced guide fins extending radially from a longitudinal, translational axis of said valve member body; and (7) said body comprising a polymeric material and being unitarily formed; and (b) a reinforcing washer entirely embedded in said valve member body, said reinforcing washer including: (1) a dish-shaped configuration convex toward said valve member body upstream side and concave toward said valve member body downstream side; (2) a plurality of apertures extending therethrough for receiving said polymeric material whereby portions of said valve member body on either side of said reinforcing washer are bonded together; and (3) a rough textured surface.
