1. A shower device comprising:
- A) a main housing adapted to be mounted on a shower stall surface;
B) a plurality of shower nozzles mounted in vertically spaced relationship in said main housing for discharging water;
C) a plurality of valves mounted in said main housing and operatively connected to respective ones of said nozzles for controlling the water flow thereto, each of said valves including;
1) a solenoid plunger movable between valve-opening and valve-closing positions,2) an electric solenoid coil for displacing said plunger toward and away from said valve-opening and valve-closing positions,3) first holding means operable independently of said coil for releasably holding said plunger in said valve-closing position, and4) second holding means operable independently of said coil for releasably holding said plunger in said valve-opening position,5) said coil being energizable to selectively release said plunger from said first and second holding means;
D) a low voltage power source operably connected to said coils for energizing said coils; and
E) manual operating controls mounted on said main housing for controlling the supply of said low voltage to said coils;
F) said main housing, said shower nozzles, said valves, and said manual controls being mountable as a single unit to said shower stall surface.

Abstract
A shower device includes a plurality of nozzles provided to a housing, supplied hot and cold water to the nozzles being turned on and off through solenoid valves which are provided in a self-maintaining type and are supplied with a power from a low voltage power source through a controller. The device is thereby made simple and easy in its installation and to be operable for a long term with considerably low voltage and small power.

8. A shower device comprising:
-
a housing, a plurality of shower nozzles mounted to said housing, a plurality of solenoid valves connected to respective ones of said shower nozzles for controlling the flow of water thereto, each of said solenoid valves including; a water supply inlet port, a supplied water discharge port and a water supply outlet communicating internally directly with said water supply inlet port, a solenoid plunger selectively actuable between valve-opening and valve-closing positions by an electric coil, and a first and second holding means operable independently of said electric coil for releasably holding said solenoid plunger in said valve-closing and valve-opening positions, respectively, said water supply outlet of each solenoid valve being coupled to said water supply inlet port of an adjacent downstream one of the solenoid valves, whereby said solenoid valves are sequentially coupled; and a lower voltage power source for energizing said electric coils. - View Dependent Claims (9, 10, 11, 12)
