1. A showerhead comprising:
- a housing having an inlet in fluid communication with a fluid source; and
an engine received within the housing and in fluid communication with the fluid source, the engine comprising;
a turbine;
a cam extending from the turbine;
a shutter operably connected to the cam and defining a first flow aperture and a second flow aperture;
a first plate in fluid communication with the inlet; and
a second plate in fluid communication with the inlet, the second plate comprising;
a first group of outlet nozzles positioned on a first side of a central axis of the engine;
a second group of outlet nozzles positioned on the first side of the central axis, adjacent to the first group of outlet nozzles;
a third group of outlet nozzles positioned on a second side of the central axis;
a fourth group of outlet nozzles positioned on the second side of the central axis, adjacent to the third group of outlet nozzles; and
wherein;
the turbine rotates as fluid flows from the inlet into the engine;
as the turbine rotates, the cam rotates, translating the shutter correspondingly between a first position and a second position;
in the first position of the shutter, the first group of outlet nozzles and third group of outlet nozzles are fluidly disconnected from the fluid inlet and the second group of outlet nozzles and fourth group of outlet nozzles are fluidly connected to the fluid inlet, and the first flow aperture is aligned with the second group of outlet nozzles; and
in the second positon of the shutter, the second group of outlet nozzles and the fourth group of outlet nozzles are fluidly disconnected from the fluid inlet and the first group of outlet nozzles and the third group of outlet nozzles are fluidly connected to the fluid inlet, and the second flow aperture is aligned with the third group of outlet nozzles.

Abstract
In one embodiment, a massage mode assembly for a showerhead is disclosed. The massage mode assembly includes a drive element, a cam, and a shutter. The drive element has a drive element length or diameter, depending on the shape of the drive element, and is rotatable about an axis by fluid flowing through the showerhead. The cam is connected to the drive element and rotates with the drive element. The shutter is operably engaged with the cam and has a shutter length that is longer than the drive element length and the rotation of the cam causes the shutter to move correspondingly.

1. A showerhead comprising:
-
a housing having an inlet in fluid communication with a fluid source; and an engine received within the housing and in fluid communication with the fluid source, the engine comprising; a turbine; a cam extending from the turbine; a shutter operably connected to the cam and defining a first flow aperture and a second flow aperture; a first plate in fluid communication with the inlet; and a second plate in fluid communication with the inlet, the second plate comprising; a first group of outlet nozzles positioned on a first side of a central axis of the engine; a second group of outlet nozzles positioned on the first side of the central axis, adjacent to the first group of outlet nozzles; a third group of outlet nozzles positioned on a second side of the central axis; a fourth group of outlet nozzles positioned on the second side of the central axis, adjacent to the third group of outlet nozzles; and wherein; the turbine rotates as fluid flows from the inlet into the engine; as the turbine rotates, the cam rotates, translating the shutter correspondingly between a first position and a second position; in the first position of the shutter, the first group of outlet nozzles and third group of outlet nozzles are fluidly disconnected from the fluid inlet and the second group of outlet nozzles and fourth group of outlet nozzles are fluidly connected to the fluid inlet, and the first flow aperture is aligned with the second group of outlet nozzles; and in the second positon of the shutter, the second group of outlet nozzles and the fourth group of outlet nozzles are fluidly disconnected from the fluid inlet and the first group of outlet nozzles and the third group of outlet nozzles are fluidly connected to the fluid inlet, and the second flow aperture is aligned with the third group of outlet nozzles. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. A showerhead comprising:
-
a housing having an inlet; a plate connected to the housing and defining a plurality of nozzles including a first bank of outlet nozzles positioned adjacent a first side of a central region of the showerhead, a second bank of outlet nozzles positioned between the first bank of outlet nozzles and the central region, a third bank of outlet nozzles positioned adjacent a second side of the central region, and a fourth bank of outlet nozzles, the third bank of outlet nozzles positioned between the fourth bank of outlet nozzles and the central region; and a massage mode assembly received within the housing and in fluid communication with the inlet and the plurality of nozzles, the massage mode assembly comprising; a turbine; a cam connected to the turbine, wherein rotation of the turbine causes rotation of the cam; and a shutter engaged with the cam such that rotation of the cam causes the shutter to translate and, as the shutter translates, one or more edge flow paths around one or more outer edges of the shutter are defined such that fluid from the inlet flows through the one or more edge flow paths to one or more nozzles of the plurality of nozzles, and one or more aperture flow paths through one or more flow apertures in the shutter are defined such that fluid from the inlet flows through the one or more flow apertures to one or more nozzles of the plurality of nozzles; wherein; the first bank of outlet nozzles and the fourth bank of outlet nozzles are positioned such that either the first bank of outlet nozzles or the fourth bank of outlet nozzles are in fluid communication with the one or more edge flow paths depending on the position of the shutter; and the second bank of outlet nozzles and the third bank of outlet nozzles are positioned such that either the second bank of outlet nozzles or the third bank of outlet nozzles are in fluid communication with the one or more aperture flow paths depending on the position of the shutter. - View Dependent Claims (14)
