1. A multi-function shower head comprising:
an upper housing having an open end for water entry;
a lower housing coupled to the upper housing opposite the open end thereof;
a base plate received in a recessed locating cavity of the upper housing or the base plate being an integral part of the upper housing, the base plate having at least one water passage and at least one direct spray hole there-through for selectively enabling water outflow from the upper housing through the base plate;
a sliding ring held by the lower housing against the base plate and having and at least a second spray pattern therein;
at least one actuator for rotating the sliding ring relative to the base plate and thereby selectively align the second spray pattern in the sliding ring with the water passages in the base plate and to adjust from a first spray pattern to the second spray pattern; and
wherein the base plate and the sliding ring are arranged and disposed with an operating mechanism to automatically adjust the water flow from the second spray pattern to the first spray pattern upon interrupting water flow through, and pressure to the base plate, the operating mechanism comprising at least one actuator supply hole, at least one pressure chamber and at least one spring cavity formed in the base plate.
