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; and
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.

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.
