Cone valve assembly
First Claim
1. A container outlet valve assembly comprising:
- a generally cone-shaped housing surrounding a container opening;
said housing extending upwardly into the container, and including radially spaced outer openings in the cone housing for lading to flow out of the container;
a cone valve located within the housing containing spaced valve openings which align with the housing outer openings when the cone valve is in open position;
a liner of low-friction material attached to one of the outer surface of the cone valve and/or the inner surface of the cone housing;
said cone valve being rigidly attached to a vertically extending shaft which is journaled for rotation in a bearing in the cone housing;
said cone valve being rotatable between a closed position in which the valve body closes the openings located in the cone valve housing, and an open position wherein the valve openings align with the housing openings to allow lading to flow out of the container.

Abstract
In accordance with the present invention, a container outlet valve assembly is provided surrounding a container outlet including a generally cone-shaped housing extending upwardly into the container, and including radially spaced outer openings in the cone for lading to flow out of the container. A cone valve is located within the housing containing spaced openings which align with the outer openings in the cone housing when the cone valve is in open position. A liner of low friction material is attached to the outer surface of the cone valve and/or the inner surface of the cone housing. The cone valve is rigidly attached to a vertically extending shaft which is journaled for rotation in a bearing in the cone housing. A hub extends radially outwardly from the lower portion of the shaft to the cone valve. The cone valve is rotatable to a closed position in which the valve body closes the openings located in the cone valve housing.
