ABSTRACT:
A sprinkler (10) includes a tubular housing (12) and a cover (14) fastened with each other. A smaller internal sleeve (70) has a similar configuration with the housing (12) and is generally positioned within the housing (12). The sleeve (70) includes a plurality of inlets (82) in the wall. A rotor (40) having radial blades (48) positioned circumferentially at intervals, is disposed in the sleeve (70) and is adapted to be impacted to rotate by the flow from the inlets (82) of the sleeve (70). A hollow spindle (52) which can be slidably moved along the axis of the rotor (40), is designedly actuated by the rotary movement of the rotor (40) and also generally in a synchronous rotation with the rotor (40). Such spindle (52) can be pushed by the water pressure to have the nozzle head (54) extend upward and exposed in an exterior for water dispersal.
