Sprinkler device

A sprinkler device for dispensing pressurized water for plant life, the device comprising:

• a sprinkler housing having an inlet, an outlet, a fluid channel disposed therebetween and configured for conveying the water through the housing, the housing defining a cavity therein in fluid communication with the fluid channel;
• spray means in fluid communication with the fluid channel configured for spraying the water;
• a shaft coupled to the spray means and extending into the housing, the shaft including a helical track formed at an exterior surface of the shaft;
• a piston slidably disposed in the cavity of the housing and configured for being acted upon by the water to impart reciprocal linear motion to the piston, the piston having a tracking element coupled to the piston and engaging the helical track, the tracking element forcing the shaft, and thus the spray means, to rotate as the tracking element moves in a reciprocal linear motion with the piston;
• and
• a return actuator coupled to the shaft for reversing directional movement of the piston to enable the reciprocal motion, to thereby use the water to drive the piston and convert the linear motion of the piston to rotational motion of the spray means, to thereby dispense the water.

A sprinkler device for dispensing water for plant life, the device comprising:

• an elongated sprinkler housing having a housing inlet, a housing outlet, and a housing fluid channel disposed therebetween configured for channeling the water through the housing, the housing defining a chamber therein in fluid communication with the housing fluid channel and configured for receiving the water;
• a sprinkler head rotatably disposed on the housing and having a head inlet in fluid communication with the housing outlet, a head outlet configured for dispersing the water, and a head fluid channel disposed therebetween configured for channeling the water through the head;
• an elongated shaft coupled to the head and extending therefrom into the housing, the shaft including a helical track formed on an exterior surface of the shaft;
• a piston slidably disposed in the chamber of the housing configured for being acted upon by the water to impart reciprocal linear motion, the piston defining a cavity therein for movably receiving the shaft, the piston having a tracking element formed thereon and engaging the helical track of the shaft, the tracking element and helical track forcing the shaft, and thus the head, to rotate as the piston reciprocates;
• and
• a return actuator coupled to the head for reversing directional movement of the piston to enable the reciprocal motion, thereby using the water to drive the piston and converting the reciprocal linear motion of the piston to rotational motion of the head, thereby dispersing the fluid.
