A showerhead may include a housing, a turbine, and a shutter. The housing may include a fluid inlet, at least one fluid outlet, and a chamber in fluid communication with the inlet and one or more outlets. The turbine and shutter may be placed in the cavity. The shutter may include at least one opening. The shutter may selectively cover and uncover fluid outlets, thus selectively fluidly connecting the fluid outlets with the chamber. Water flowing through the housing causes the turbine to spin. As the turbine spins, the shutter rotates at a slower speed than the turbine to produce a periodic interruption of water flow through the outlets by covering and uncovering the outlets as the shutter rotates within the housing.
1. A showerhead comprising a housing defining a chamber in fluid communication with a fluid inlet and at least one fluid outlet, the housing further defining an annular recess and having a first engagement feature formed in an interior surface of the housing;a turbine received within the chamber; an
1. A showerhead comprising a housing defining a chamber in fluid communication with a fluid inlet and at least one fluid outlet, the housing further defining an annular recess and having a first engagement feature formed in an interior surface of the housing;a turbine received within the chamber; anda shutter at least partially received within the annular recess of the housing, operatively associated with the turbine, and having a second engagement feature, whereinrotation of the turbine causes rotation of the shutter;engagement of the first engagement feature with the second engagement feature causes a rotation rate of the shutter that is less than a rotation rate of the turbine; andas the shutter rotates, the shutter fluidly connects and disconnects the fluid inlet and the at least one fluid outlet. 2. The showerhead of claim 1, wherein the first engagement feature comprises a plurality of gear teeth. 3. The showerhead of claim 1, wherein the second engagement feature comprises a plurality of gear teeth. 4. The showerhead of claim 1, wherein the first engagement feature comprises a first number of gear teeth, and the second engagement feature comprises a second number of gear teeth. 5. The showerhead of claim 4, wherein the first number is greater than the second number. 6. The showerhead of claim 1, wherein the shutter comprises a substantially non-planar body including an upper shutter portion and a lower shutter portion, and wherein the upper shutter portion comprises one or more fluid obstructing members. 7. The showerhead of claim 6, wherein the fluid obstructing members comprise radially extended members which extend arcuately about the upper shutter portion. 8. The showerhead of claim 6, wherein the lower shutter portion comprises an annular member and the second engagement feature is defined in a periphery of the annular member. 9. The showerhead of claim 8, wherein the annular member is received within the annular recess of the housing. 10. The showerhead of claim 1, wherein the at least one fluid outlet comprises a plurality of fluid outlets, andthe plurality of fluid outlets are disposed radially outward with respect to the first engagement feature. 11. The showerhead of claim 1, wherein the turbine and the shutter rotate in opposite directions. 12. The showerhead of claim 1, wherein the turbine and the shutter rotate in the same direction. 13. The showerhead of claim 1, wherein the rotation rate of the shutter is no greater than approximately 1/15th of the rotation rate of the turbine. 14. The showerhead of claim 1, wherein the turbine includes an eccentric cam; andthe shutter includes an opening for receiving the eccentric cam. 15. The showerhead of claim 1, wherein a center of the shutter moves in a substantially eccentric path around a center of the turbine. 16. The showerhead of claim 1 further comprising a jet disk operatively associated with the turbine, the jet disk defining at least one passage extending therethrough, wherein the at least one passage is positioned with respect to the turbine such that a flow of fluid through the at least one passage effects rotation of the turbine. 17. The showerhead of claim 1, wherein the shutter comprises an annular member seated in the annular recess of the housing and the second engagement feature includes an integer number of second features distributed around a periphery of the annular member;the first engagement feature of the housing comprises an integer number of first features incorporated within a sidewall defining the annular recess;the number of first features is different than the number of second features; androtation of the shutter selectively engages the first features with the second features. 18. The showerhead of claim 17, wherein the number of second features is less than the number of first features. 19. The showerhead of claim 1, wherein a portion of the shutter received within the annular recess of the housing is encompassed by the first engagement feature. 20. The showerhead of claim 19, wherein the second engagement feature extends from the portion of the shutter received within the annular recess of the housing. 21. The showerhead of claim 1, wherein the first engagement feature defines the annular recess within the housing. 22. The showerhead of claim 1, wherein the first engagement feature is disposed radially inward with respect to the at least one fluid outlet. 23. The showerhead of claim 1, wherein the interior surface forming the first engagement feature is a sidewall defining the annular recess. 24. A showerhead, comprising a housing defining a chamber in fluid communication with a fluid inlet and at least one fluid outlet, the housing defining a first engagement feature disposed radially inward with respect to the at least one fluid outlet;a turbine received within the chamber;a shutter received within the chamber and operatively associated with the turbine, the shutter including a second engagement feature; whereinrotation of the turbine causes rotation of the shutter;engagement of the first engagement feature with the second engagement feature causes a rotation rate of the shutter to be less than a rotation rate of the turbine; andas the shutter rotates, the shutter fluidly connects and disconnects the fluid inlet and the at least one fluid outlet. 25. The showerhead of claim 24, wherein the turbine includes a cam; andthe shutter includes an opening for receiving the cam; whereinas the turbine rotates, the cam rotates to drive rotation of the shutter. 26. A showerhead, comprising a housing defining a chamber in fluid communication with a fluid inlet and at least one fluid outlet, the housing including a first engagement feature disposed radially inward with respect to the at least one fluid outlet; anda cycloidal drive comprising a turbine received within the chamber, the turbine including an eccentric cam; anda shutter received within the chamber and operatively associated with the turbine, the shutter including a second engagement feature and an opening for receiving the eccentric cam, whereinrotation of the turbine causes rotation of the shutter; andengagement of the first engagement feature with the second engagement feature causes a rotation rate of the shutter to be less than a rotation rate of the turbine.
