Oscillating sprinkling device
First Claim
Patent Images
1. An oscillating sprinkling device, comprising;
- a rotary driving element rotatable by a sprinkling liquid alternately in one direction of rotation and the other;
a sprinkler element mounted for oscillating rotation and permanently kinematically connected to the rotary driving element, the sprinkler element pivoting about an approximately horizontal axis alternately in one direction of its oscillating rotation and the other, according to the rotation of the rotary driving element;
control means for effecting at the end of the pivoting of the sprinkler element in either direction, a change of the direction of rotation of the rotary driving element; and
duct means defining a duct for supplying the rotary driving element with a jet of sprinkling liquid under pressure, the duct means having a movable outlet part;
the control means comprising an element for deviating the jet of liquid from the movable outlet part of the duct alternately in first and second directions, each corresponding to one of the directions of rotation of the rotary driving element, the deviating element cooperating with the movable outlet part of the duct to move the element in first and second directions of deviation of the jet.

Abstract
In an oscillating sprinkling device, control of the change of direction of oscillation of a sprinkler is achieved by deviating a jet of the sprinkling liquid impinging a driving turbine to change the direction of rotation of the turbine.
