Abstract
A self-governing spray apparatus for irrigation or cleaning purposes is provided. A spray nozzle at the end of a moment arm and substantially perpendicular to an axis of rotation creates a reaction torque to distribute a spray by spinning. A hinged member thrust into the spray pattern by means of the centrifugal force caused by the spin deflects a portion of the spray and results in a braking action. An equilibrium angular speed is thereby reached by self-correcting means.
Claims10
A self-governing spray apparatus, comprising:
- a supply of pressurized fluid;
- a spinning apparatus connected to the supply having an axis of rotation and at least one nozzle, the nozzle at the end of a moment arm pivoting about the axis of rotation, the nozzle forming a spray pattern, the spray pattern directed substantially perpendicular to the axis of rotation, wherein pressurized fluid flowing through the spinning apparatus causes rotation thereof;
- and
- a means for changeably deflecting an amount of the spray pattern, the deflection countering the thrust from the flow and resulting in a reduction of rotational speed, the amount of deflection responsive to variations in the pressure, whereby a preferred speed of rotation is governed.

- and
- a hinged member swinging from the moment arm, the hinge axis parallel to the axis of rotation, the location of the hinged member proximate to the nozzle such that its extent intersects the spray pattern, the mass and wetted area of the hinged member sufficient to impede the rotational speed of the spinning apparatus by centrifugally deflecting the spray pattern to achieve a governed speed of preference
