ABSTRACT:
A valve in which a blade having an opening is moved between two oval-shaped seals, each having a pair of spaced circular inner seals, all housed in a valve body. One set of aligned circular seals has a central opening flanked by two opposing and aligned openings through the valve body. When the opening of the blade is positioned in alignment with the opening through the seals and the body, the valve is, of course, opened. When the opening of the blade is repositioned opposite the other set of o-shaped seals, the valve is very tightly closed.
