Hand-held pulsating shower

摘要

A shower head that employs a rotor for effecting a pulsed jet-discharge is embodied in a construction by means of which the user may selectively secure either a pulsed jet-discharge or continuous spray discharge from the shower head. The rotor is housed between upstream and downstream housing parts that are axially movable between pulsed discharge and spray discharge positions, by relative rotation of said upstream and downstream housing parts through a screw-threaded connection so that the user's selection between pulsed jet-discharge and continuous spray is achieved by a simple rotary motion of the downstream housing part. A selectively releasable stop member limits rotation in one direction to insure proper axial spacing of said upstream and downstream housing parts when pulsed jet-discharge is selected. When the upstream and downstream housing parts are axially spaced closest together, the rotor is driven, and the assembly functions to provide pulsed jet-discharge from only one set of apertures, and when said parts are spaced further apart axially, then other apertures in the downstream housing part are exposed so that a continuous spray of discharge is achieved through all apertures.
