Abstract: A water pressure driven massage apparatus has a casing carrying a plurality of captive massage members in the form of balls. The balls are mounted in guide passages with some clearance to move inwardly and outwardly with respect to the casing. When the device is pressed against a body part to be massaged, the balls are pushed back against an eccentric projection on a water-driven turbine, causing them to follow a periodic massaging stroke. When not pressed against a user, the balls are forced by water pressure to an outermost position at which the guide passages are sealed by the balls against flow and the water then passes through spray jet guides are provided in the surface of the casing.

Abstract: A water pressure powered massage and spray apparatus includes a casing, a plurality of axially movable massage members projecting from a working surface of the casing to perform the massaging action, a water connection and a drive mechanism including a water turbine to drive the massage members. The massage members are individually held in the casing in such a way that they have a range of free axial movement, but cannot drop out. The water turbine has at least one eccentric projection extending toward the massage members for causing axial movement of the massage members. In their extreme outward position, the massage members substantially close the working surface of the casing, so that spray jets can pass out through spray jet guides provided in the casing, thereby automatically converting the apparatus between use as a massage and use as a spray.
