"APPLIANCES FOR REGULATING WATER FLOW THROUGH A ASPERSOR, AND FOR REGULATING WATER WITH A VARIABLE FLOW OR PRESSURE, A DISPERSER FOR WATER DISTRIBUTING, AND APPLIANCE FOR REGULATING OPERATION OF A ASPECTOR INCLUDING A MECHANIZATION." A sprinkler throttle module has a compact arrangement with a displaceable member having an upper cavity for receiving debris contained in the water flow, and a portion of a bypass valve may alternatively move within it. The module includes a stator plate directing water into a drive mechanism, such as a turbine drive mechanism. The displaceable member receives fluid flow from a radially external direction and is sealed with a cup portion receiving the displaceable member to define a cup cavity. An outer module surface is separated from a sprinkler housing to define an exhaust cavity. A pressure relief vent communicates with the cup cavity, an exhaust channel between the cup portion and the outer surface, the exhaust cavity, and the external environment. The exhaust cavity and the cup portion provide receptacles. to the debris deposit. Ribs around an exhaust duct opening with the exhaust cavity generally prevent debris from entering the exhaust duct.
