Irrigation Device With Rotating Deflector

A deflector for an irrigation device comprising:

• a first side including a first rotating engagement surface extending therefrom;
• and
• a second side including:
• a first flow channel for a first fluid stream with a first exit oriented to generate a first rotational force acting on the deflector;
• a second flow channel for a second fluid stream with a second exit oriented either to generate no rotational force or a second rotational force opposing the first rotational force;
• and
• a second rotating engagement surface extending therefrom and terminating upstream of the first exit and the second exit.

An irrigation device comprising:

• a fluid inlet configured to receive fluid from a fluid source;
• a nozzle in fluid communication with the fluid inlet and comprising a flow passage;
• a frame engaging and extending across the nozzle;
• a first ceramic surface associated with the frame or nozzle;
• a deflector having a first side supported by the nozzle and a second side supported by the frame, the deflector continuously rotating when subjected to fluid from the nozzle;
• and
• a second ceramic surface associated with the deflector,
• wherein the deflector is movable between an operational position, in which the frame engages the deflector and the first ceramic surface and the second ceramic surface engaging during rotation, and a non-operational position where the deflector seats on the nozzle.
