Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
191 words
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.
Claim 2
Dependent Claim
191 words
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.
Claim 3
Dependent Claim
50 words
A sprinkling device according to claim 1, in which the duct is generally fixed and the deviating element is a deflector disposed at the movable outlet part of the duct and enabled to occupy first and second positions corresponding to the first and second directions of deviation of the jet.
Claim 4
Dependent Claim
26 words
A sprinkling device according to claim 2, in wich said deflector defines at least one wall of a passage through which the jet of liquid passes.
Claim 5
Dependent Claim
33 words
A sprinkling device according to claim 3, in which said deflector has two faces opposed to one another and is pivotally mounted about an axis disposed between said faces and facing said duct.
Claim 6
Dependent Claim
51 words
A sprinkling device according to claim 3, in which said deflector has two inclined faces with a common edge directed towards an outlet of the duct, said deflector been movable transversally in front of said outlet to alternately place each of its faces in the trajectory of the jet of liquid.
Claim 7
Dependent Claim
33 words
A sprinkling device according to claim 5, in which the deflector is pivotally mounted about an axis spaced apart from said outlet of the duct beyond said common edge of the two faces.
Claim 8
Dependent Claim
24 words
A sprinkling device according to claim 6, in which the pivoting axis of the deflector is coaxial to that of the rotary driving element.
Claim 9
Dependent Claim
35 words
A sprinkling device according to claim 5, in which said inclined faces of the deflector are associated with respective facing walls of the deflector to define two passages for guiding the deviated jet of liquid.
