Patent attributes
A sprinkler has a housing with an inlet portion and an outlet portion in which a first outlet aperture is formed. The first outlet aperture may cooperate with other outlet apertures to define a spiral shape. A cam is disposed upstream of the first outlet aperture. The cam is rotatable about a cam axis to cover varying portions of the outlet apertures. After moving through the outlet apertures, water strikes a deflector and is sprayed outward from the head. The orientation of the cam establishes an arc angle through which water is sprayed, including a full-circle spray pattern. The deflector may be stationary or rotatable. In one alternative configuration, the outlet apertures and each leads to a different strip nozzle. The cam has an open portion that can be rotated into alignment with each of the outlet apertures to determine which of the strip nozzles are active.
