A sprinkler includes a compartment that surrounds its riser portion in an offset or asymmetrical configuration. More specifically, the distance of the compartments walls from those of the riser vary (i.e., increase or decrease) at different locations surrounding the riser. Put another way, the riser is closer to one side of the compartment than other sides of the compartment. This non-concentric configuration allows larger components to fit inside the compartment than would otherwise fit if the riser was symmetrically surrounded by the compartment.

Sprinkler with internal compartments

A sprinkler height adjustment mechanism is described that can be used to increase the height of a top cover and a top of the riser relative to the sprinkler body. The height adjustment mechanism is particularly useful for sprinklers with compartments having removable tops, however, a similar design can also be adapted for sprinklers without compartments (e.g., components that connect to a sprinkler flange or the sprinkler riser).

Sprinkler with height adjustment

The present invention includes an improved sprinkler design having a magnetic sensing system for determining the position of the riser nozzle, a waterproofed motor housing and related cables, configurable sprinkler body compartments, and a pilot valve with a check valve assembly, both of which are located within the sprinkler body.

Sprinkler assembly

A turf cup is described that is mounted to a top of an irrigation sprinkler. The turf cup includes an outer sleeve and a plurality of drainage passages.

One embodiment provides an asymmetrical nozzle housing within a nozzle base of a sprinkler which, when rotated, changes its angular orientation relative to the nozzle base. Since the nozzle is disposed within the nozzle housing, it similarly changes angular orientation relative to the nozzle base, thereby modifying the trajectory of ejected water during irrigation. In this respect, a user can change the trajectory of a watering stream by simply rotating the nozzle housing.
