Abstract
A sprinkler assembly with a nutating distribution plate can improve even distribution of water. The distribution plate can tilt and/or translate upon water impinging the distribution plate to disperse water in different directions. The sprinkler assembly can have a deflector assembly including the distribution plate, a spindle supported by a bearing, and a contact portion downstream of the distribution plate to contact a housing that limits a range of movement of the distribution plate. The sprinkler assembly can be disassembled and reassembled with minimal tools and effort for servicing.
Claims21
A sprinkler assembly comprising:
- an inlet configured to receive water;
- a bracket supported by the inlet;
- a nozzle in fluid communication with the inlet and positioned downstream of the inlet, the nozzle being configured to direct the water out of the nozzle along an axis;
- a deflector assembly positioned downstream of the nozzle, the deflector assembly being configured to move with respect to the axis in one or both of a rotational and a tilting direction, the deflector assembly comprising:
- a distribution plate positioned downstream of the nozzle and configured to deflect water from the nozzle, and
- a spindle extending from a side of the distribution plate facing away from the nozzle, the spindle being configured to move with respect to the axis in at least the tilting direction;
- and
- a housing supported by the bracket and comprising:
- one or more surfaces configured to contact the spindle so as to limit movement of the deflector assembly in one or both of the rotational and the tilting direction about the housing, and
- a nozzle carrier and a spare nozzle, the nozzle carrier being positioned below the spindle and configured to releasably secure the spare nozzle to the housing.

A sprinkler assembly comprising:
- an inlet;
- a bracket connected to the inlet;
- a nozzle in fluid communication with the inlet and positioned downstream of the inlet, the nozzle configured to direct water out of the nozzle along a nozzle axis;
- a deflector assembly downstream of the nozzle and configured to move with respect to the nozzle axis in one or both of a rotational and a tilting direction about a pivot point, the deflector assembly comprising:
- a distribution plate configured to deflect water from the nozzle, and
- a spindle extending from a side of the distribution plate facing away from the nozzle and terminating at a distal end, the distal end comprising a receptacle, the spindle being configured to move with respect to the nozzle axis in at least the tilting direction;
- a spare nozzle;
- and
- a housing supported by the bracket and comprising a nozzle carrier, the housing being configured to limit movement of the deflector assembly in at least one or both of the rotational and the tilting direction about the pivot point, the nozzle carrier being positioned below the spindle and configured to releasably secure the spare nozzle.
