Abstract
A disk member selectively blocks flow across a fluid conduit formed in a body. The disk member may include a shaft having a longitudinal axis, a ring member disposed on the shaft, a sealing member disposed on the shaft, and a pressure applying surface in contact with the sealing member. The pressure applying surface may be non-orthogonal to the longitudinal axis.
Claims17
An apparatus for controlling a fluid flow, the apparatus comprising:
- a body having a fluid conduit;
- and
- a disk member selectively blocking flow across the fluid conduit, wherein the disk member includes:
- a shaft having a longitudinal axis;
- a sealing member disposed on the shaft;
- a pressure applying surface in contact with the sealing member, wherein the pressure applying surface is non-orthogonal to the longitudinal axis;
- and
- a ring member disposed on the shaft, the sealing member being positioned between the ring member and the pressure applying surface.

An apparatus for controlling a fluid flow, the apparatus comprising:
- a body having a fluid conduit formed of a first section and a second section;
- a rod configured to translate in the body, the rod having a flow passage in communication with the first fluid conduit section;
- a first and second sleeve members disposed in the body, each sleeve member having a bore in communication with the second fluid conduit section;
- and
- a disk member disposed in the rod and between the first and second sleeve members, wherein the disk member includes:
- a shaft having a longitudinal axis and a medial flange;
- a sealing member disposed on the shaft and on each side of the medial flange;
- a pressure applying surface in contact with each sealing member, wherein the pressure applying surfaces are non-orthogonal to the longitudinal axis;
- and
- a ring member disposed on each end of the shaft, each sealing member being positioned between an associated ring member and pressure applying surface.
