ABSTRACT:
The present invention discloses a reversible turbine-driven sprinkler head which includes a vaned turbine motor for rotatably driving a nozzle. The turbine is unresponsive to the norml flow of fluid through the sprinkler head to the nozzle. Switchable deflection means are included for deflecting the flow of fluid through the body against the turbine to cause rotation thereof in either of two directions. By deflecting the fluid flow to cause the turbine to rotate in one direction, the nozzle is rotated in one direction. By switching the direction of fluid deflection to cause the turbine to flow in the opposite direction, the nozzle is rotated in the opposite direction. Adjustable means are provided for setting the positions relative to the rotation of the nozzle whereat the deflection of the fluid flow is reversed, whereby the nozzle is caused to repeatably oscillate between a first and a second position.
