ABSTRACT:
A ball-type water sprinkler of the sector type includes two inlets into the ball chamber oriented to direct the water to flow in opposite directions circumferentially around the chamber, and a shutter rotatable with the rotor and movable either to a first position with respect to the rotor covering one inlet and uncovering the other inlet to cause the water to flow in a first direction, or to a second position uncovering the one inlet and covering the other inlet to cause the water to flow in the opposite direction. The shutter is actuated by a member rotatable with the rotor and cooperable with the sector stops of the sprinkler, the actuator being coupled to the shutter by an over-center spring coupling producing a snap action movement of the shutter to either its first or second positions.
