Valve for reciprocating pump assembly
First Claim
1. A valve member for a reciprocating pump assembly, the valve member comprising:
- a valve body comprising a first frusto-conical surface, the valve body defining an outside annular cavity formed therein; and
a seal extending within the outside annular cavity, the seal comprising;
a first tapered and circumferentially-extending surface adapted to sealingly engage a tapered surface of a valve seat of the reciprocating pump assembly;
an annular bulbous protrusion from which the first tapered and circumferentially-extending surface angularly extends, the first tapered and circumferentially-extending surface extending between the annular bulbous protrusion and the first frusto-conical surface of the valve body;
a channel formed exteriorly in the seal and positioned between the annular bulbous protrusion and a top surface of the valve body; and
a circumferentially-extending tab extending upwardly from the channel and encircling the top surface of the valve body.

Abstract
The valve member includes a valve body and a seal. The valve body defines a first frusto-conical surface and an outside annular cavity. The seal extends within the outside annular cavity and includes a first tapered and circumferentially-extending surface adapted to sealingly engage the tapered surface of the valve seat. In another aspect, the seal includes an annular bulbous protrusion from which the first tapered and circumferentially-extending surface angularly extends, the first tapered and circumferentially-extending surface extending between the annular bulbous protrusion and the first frusto-conical surface of the valve body. In another aspect, an offset distance is defined between the first frusto-conical surface of the valve body and at least a portion of the first tapered and circumferentially-extending surface of the seal, the offset distance extending in a direction that is perpendicular to at least the first frusto-conical surface of the valve body.

11. A valve member for a reciprocating pump assembly, the valve member comprising:
-
a valve body comprising a first frusto-conical surface, the valve body defining an outside annular cavity formed therein; and a seal extending within the outside annular cavity, the seal comprising; a first tapered and circumferentially-extending surface defining a first acute angle and being adapted to sealingly engage a tapered surface of a valve seat of the reciprocating pump assembly; and a second tapered and circumferentially-extending surface defining a second acute angle and extending angularly between the first tapered and circumferentially-extending surface of the seal and the first frusto-conical surface of the valve body; wherein the valve member defines a first axis from which the first and second acute angles are measured, the first acute angle being measured in a first angular direction from the first axis, the second acute angle being measured in a second angular direction from the first axis, said second angular direction being the same as the first angular direction; and wherein an offset distance is defined between the first frusto-conical surface of the valve body and at least a portion of the first tapered and circumferentially-extending surface of the seal, the offset distance extending in a direction that is perpendicular to at least the first frusto-conical surface of the valve body. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
