A shower jet generating device for a shower head, illustratively for a sanitary shower head, including a shower jet disk delimiting a fluid chamber on an outlet side and including at least one jet outlet opening leading out of the fluid chamber and at least one overpressure valve opening, and comprising at least one overpressure valve disposed on the overpressure valve opening. The overpressure valve illustratively includes an overpressure outlet opening leading out of the fluid chamber, an immobile valve seat and a valve body capable of movement controlled by a fluid pressure in the fluid chamber and interacting with the valve seat, which valve body, in a normal pressure position, rests against the valve seat, thereby closing the overpressure outlet opening, and, in an overpressure position, is lifted off the valve seat, thereby exposing the overpressure outlet opening.

A spray-head assembly includes a pipe structure and a valve-spool. The pipe structure includes a liquid inlet, a flow pathway, and a valve-port. The flow pathway includes an air-flow pathway arranged obliquely with respect to a central axis of the liquid inlet. A bottom end of the air-flow pathway communicates with the liquid inlet. The valve-port is arranged at a top end of the air-flow pathway. The valve-spool is arranged in the flow pathway and configured to control opening and closing of the valve-port.

A tank system is described for dropping fluid onto a passing vehicle. The tank system includes a tank with a fluid supply inlet. A discharge adapter is attached with the tank and proximate the trough portion, the discharge adapter having a discharge adapter plate with a plurality of holes formed therethrough. Optionally, a soap or solution injector is included for injecting soap or wax, etc., into the water flow to create a fluid mix that is supplied to the tank. An air motor is included for providing air to an air manifold that is disposed within the tank. When air is introduced into the fluid mix, bubbles are created. As the fluid mix and bubbles fill the tank, they pass from the tank into the discharger adapter, where they fall onto a vehicle passing below.

An electronic fountain light, includes a barrel. A separator is provided in a cavity of the barrel. The separator divides the barrel into a water storage compartment and a battery compartment. A first water tank is provided in the water storage compartment. A first illuminant is mounted on the separator. The separator is provided in a concave manner along a direction towards the battery compartment to form a mounting slot. An impeller is mounted in the mounting slot. A plurality of first magnets is fixed on the impeller. A rotating disk and a drive motor for driving the rotating disk to rotate are disposed in the battery compartment. A plurality of second magnets is mounted on the rotating disk. The drive motor drives the rotating disk to rotate, and by means of mutual attraction of the second magnets and the first magnets, the impeller is driven to rotate.

A selectively-illuminable decorative water feature in the form of an assembly includes a base, casing, and a light source in communication with a semi-translucent or translucent fixture. The base may, for example, be a portion of a component/feature of a swimming pool, a spa or a fountain. The casing and light source may be mounted within the base and the fixture attached to a front surface of the base. The translucence or semi-translucence of the fixture creates an illumination effect due to limited transmission of light, emitted from the light source, through the feature. The water feature may take on a variety of forms, including, for example, decorative fixtures, receptacles, a bowl-shaped fixture, and a hand grip attached to a structural surface of a pool, spa or fountain.
