Abstract
In a spa having a tank for body immersion, a flexible tube exhausting pressurized water into the tank having a free end adapted to whip usually in a vertical plane by reaction of the exhausting water. The tube has a cross-section with flattened upper and lower surfaces so the tube bends easier in the vertical plane and whips in a reciprocating motion in the vertical plane. Upper and lower limits on tube travel are formed by roller abutments that are supported by a housing. The housing has a series of holes in which the rollers are journaled extending in lines generally parallel to the tube so that the rollers can be changed in location in order to relocate upper and lower tube bending and reversing points as needed to produce effective whipping action of the tube.
