<p>A fluid device driven solely by input fluid to reciprocate a driven member in the device. The device is readily attached to a normal or special fluid supply system. The device can produce a pulsating fluid output that may be used for cleaning, especially for cleaning around and between teeth, as well as for cleaning and massaging gums. The device includes a main fluid flow path between the inlet and the outlet to drive an actuating apparatus and to transfer most of the input fluid out through the outlet. The actuating apparatus includes a driven member (66), a control system, and a drive system. The drive system includes a fluid drive port and a biasing system (88) for providing the driving force to reciprocally drive the driven member (66) and for aiding cyclic movement of the driven member. The biasing system may be a compression air chamber (88) and the control system may be a drip valve system (79). </p> |
