Abstract
A self-cleaning valve includes a fixed valve member having inlet means, a movable valve member positioned adjacent the fixed valve member and having an inlet port movable into register with said inlet means, and seal means carried by the fixed valve member and in sealing engagement with the movable valve member. A shear member is positioned on the opposite side of the movable valve member from the seal means and is in intimate contact with the movable valve member. Movement of the movable valve member to control the flow of fluid passing from the inlet means to the inlet port causes the inlet port to slidingly move adjacent and between the shear member and the fixed valve member to remove or break up foreign material held by the inlet port.
