Abstract
A snap-action toggle valve reverses the direction of an oscillating sprinkler powered by a paddle-piston motor. Adjustable stops on the sprinkler tube trip the valve at the end of each sweep, alternately opening left and right motor chamber channels interconnected to a sprinkler supply channel feeding the sprinkler tube without interruption. A special vane on the sprinkler tube where it intercepts the sprinkler supply channel prevents vortex action. The edges of the paddle-piston are sealed to the motor chamber by a flanged slip-on wiper.
