Abstract
The present invention relates to improved fluid valves actuable by a non-axial movement of an actuation stem. The non-linear actuable valves embodied in the present invention maintain pressure containment through a novel approach over the prior-art. The exemplary embodiments teach improved non-linear actuable valves that reduce the chances for seal extrusion, particularly at elevated retaining pressure, while keeping the component count low, and are capable of functioning under both high and low pressure.
Claims2
A fluid valve actuable by a non-axial force comprising;
- a valve body defining an interior bore comprising a first diameter;
- a valve seat defining an end of said bore, wherein said valve seat is formed to include an aperture comprising a second diameter extending therethrough;
- a rocker seat comprising:
- an arrowhead shaped portion moveably disposed within said bore and having a third diameter, wherein said third diameter is less than said first diameter and greater than said second diameter;
- a cylindrical portion attached to said arrow-head shaped portion and extending outwardly therefrom, wherein:
- said cylindrical portion comprises a fourth diameter;
- said fourth diameter is less than said second diameter;
- said cylindrical portion extends through said aperture and outwardly from said valve body;
- an annular seal disposed between said arrow-head shaped portion and said valve seat;
- and
- an annular floating seal support disposed between said seal and said cylindrical portion, wherein a first portion of said annular floating seal support extends into said aperture, and wherein a second portion of said annular floating seal support extends into said bore.
