Patent ID: 8028935

Claim:
A showerhead comprising a showerhead engine including at least two spray modes; and a flow control device operatively associated with the showerhead engine, wherein the flow control device comprises a flow control ring and a flow control housing; the flow control housing including first and second fluid chambers and a flow notch in fluid communication with the first and second fluid chambers; the flow control ring is received by an outer surface of the flow control housing; the flow control ring including sidewalls defining a recess in an inner surface of the flow control ring; the flow control housing and the recess defining a third fluid chamber in selective fluid communication with the first and second fluid chambers; selective movement of the flow control ring relative to the flow control housing enables and ends fluid communication between the third fluid chamber and at least one of the first and second fluid chambers; the flow control ring is movable relative to the flow control housing from a first position in which a stop defined in an inner surface of the flow control ring or the outer surface of the flow control housing abuts against a first end of a groove defined in the other of the inner surface of the flow control ring or the outer surface of the flow control housing, to a second position in which the stop abuts against a second end of the groove; and in the first position, the recess of the flow control ring engages with an engagement surface of the flow control housing and aligns the recess relative to the flow control housing such that fluid flows through the fluid chambers and; in the second position, a seal member arranged in the flow control ring engages with the engagement surface of the flow control housing such that the flow control ring permits the flow of fluid between the first and second fluid chambers by way of the flow notch and prevents fluid flow though the third chamber, thereby substantially pausing fluid flow for any of the at least two spray modes.
