Abstract
A spray head is disclosed which is capable of generating a pulsating spray and is particularly suited for domestic shower and bath use. The spray head employs a rotor which, as it is turned by flowing water, axially reciprocates to alternately open and restrict a water flow passageway through the spray head. Means are also provided for adjusting the spray head to provide a continuous spray with the rotor continuing to rotate, thus reducing the risk of rotor clogging or freezing.
