ABSTRACT:
A stem has an upper central bore terminating a short distance from the lower end, with transverse holes for connecting the bore with the outside of the stem. Below these holes is a spiral rib, such as an Acme thread, with the lower end of the stem being beveled. A housing having interfitting threads with the stem and adjustable along the stem has a central bore terminating in a conical surface corresponding to the bevel of the stem, from which a hole extends to the lower end of the housing. A restricted hole in a passage leading to the stem, as in the ball of a ball joint, restricts flow through the head to on the order of 2 to 1.6 gallons per minute, for certain sizes of holes tested. A pair of opposed holes, spaced equidistantly from the bottom of the stem, extend through the rib area into a short counterbore at the lower end of the stem, and result in the production, at certain longitudinal positions of the housing relative to the stem, of pulsating, oscillating jets having a massage effect. These holes may be positioned at different places relative to the rib and to the channel between turns of the rib.
