Swivel drive for fan-jet sprinkler

摘要

A drive mechanism for a swiveling fan-jet sprinkler comprising a water-driven turbine, a reduction gear drive and, on the final drive shaft of the latter, a rotary cam member cooperating with a cam follower on the nozzle cylinder. The rotary cam member is preferably a swash plate with an elliptical torus-like rim, engaged by a fork-shaped cam follower. The mechanism may include adjustability of the swivel angle of the nozzle cylinder through a swash plate with an adjustable inclination on the final drive shaft.
