ABSTRACT:
A toilet flush valve having a tank ball and rod, with a pair of guide arms mounted on the overflow pipe. The guide arms are spaced apart vertically a distance greater than half the length of the tank ball rod. The upper guide arm is located a fraction of an inch below the top end of the rod; and has a hole through which the rod passes. The hole is only slightly larger in diameter than the rod, so that the latter slides freely through the guide arm, but without appreciable side play. The lower guide is spaced above the tank ball a distance sufficient to allow the tank ball to rise clear of the outlet seat, and has a hole with diameter approximately 2 to 2.5 times the diameter of the rod, so that the latter has sufficient side clearance to allow the ball to center itself on its seat. A knob is attached to the rod between the guide arms closely adjacent the lower guide arm. A lift rod depends from the lift arm of the toilet handle, and its lower end extends between the knob and lower guide arm, and slidably engages the tank ball rod. When the arm is raised by the toilet handle, the lift rod engages and lifts the knob to unseat the ball. As the ball descends to its seat, the widely spaced guide arms accurately guide it so that it centers itself precisely on the seat.
