<p>Device on a valve for shutting and/or controlling a flow of liquid, consisting of a valve box with a chamber, to which is connected an inlet and an outlet and with a valve body in the form of a ball or cylinder so arranged as to be capable of displacement with a rolling motion from a closed position against a valve seat to an open position away from the seat. The valve is specifically intended for use as a tank valve in toilet (water-closet) cisterns. The ball is supported so as to move freely in a blind hole in a body which is cylindrical and which is supported so as to rotate in the chamber. The body may be moved from a position where the blind hole and the ball are above the valve seat to a position where these components are to one side of the seat. The blind hole is so arranged as to be approximately at right angles to the longitudinal axis of the body, and the valve seat is situated inside the valve box or in a component which is attached to it.</p> |
