Abstract
A control device for a shower head assembly includes is engaged with an inlet of the shower head and includes a tubular body which has a central piece located at a center thereof. A plurality of plates are connected between the central piece and an inner periphery of the tubular body. A flexible ring is mounted to the central piece such that a path is defined between the inner periphery of the tubular body and an outer periphery of the flexible ring. The flexible ring is expanded by water pressure to narrow the size of the path so that the maximum volume of the water can be controlled.
