(54) Lawn sprinkler


(57) A lawn sprinkler comprising first chamber (20) of circular section to which pressurised water is arranged to be supplied from a second chamber (16) via a plurality of angled bores (24) in a connecting wall (18). The bores (16) are positioned and orientated such as to establish in the first chamber a body of water rotating about the chamber axis. A rotor (26) is mounted for free rotation about an axis coincident with the longitudinal axis of the first chamber (20) and carries a plurality of angularly spaced, generally radially directed vanes (46), at least parts of which project into the first chamber (20) so as to be driven by the rotating body of water to thereby rotate the rotor.
