Abstract
A sprinkler includes a pipe having a number of outlet openings for outward flow of the water, and a number of rings rotatably engaged on the pipe and each having an orifice for selectively aligning with the outlet opening of the pipe and for selectively blocking the outlet opening, such that the outlet openings of the pipe may be selectively opened or blocked by the rings. A housing is engaged on the pipe and has a number of apertures for slidably receiving the actuating ears of the rings to limit the movement of the ring relative to the pipe.
