ABSTRACT:
A rotary sprinkler including a stationary cylinder, one end of which is connectable to a water supply line, a central rod rotatably mounted inside the cylinder, having at least one supply duct passing therethrough and directly leading to a sprinkler head attachable to the upper end of the rod, as well as a plurality of separate control ducts inside, and ports communicating with the ducts and leading to the outer surface of, the rod, at least one port communicating with the supply duct. The sprinkler further comprises a piston riding on the central rod and slidable in the cylinder between an upper and a lower position, the piston dividing the cylinder into an upper chamber and a lower chamber, coupling means being provided for linking the central rod to the piston in rotation while permitting the piston one degree of freedom of stroke-like, reciprocating translatory movement relative to the central rod, a valve member located on the central rod for controlling at least some of the ports to the effect of producing the reciprocating, translatory movement, and at least one set of camming means kinematically linking the stationary cylinder and the slidable, piston.
