PURPOSE:To balance the injection pressure of a shower nozzle and besides stabilize the speed at which the nozzle rises and falls by arranging a feed water system for feeding a shower nozzle with shower water and a feed water system for feeding a hydraulic cylinder with driving water independently of each other. CONSTITUTION:A feed water system for feeding a switching valve 1 has a feed water line to a shower nozzle 2 and a feed water line to a water hydraulic cylinder 7 for driving the shower nozzle 2, both of which are independent of each other, and the system is such that waste water from a switching valve 1 for switching a water channel to the water hydraulic cylinder 7 is released downwards from the drainage hole 1a of the valve 1. A constant flow valve 38 is stored on the side of the intake of a port A which is on the side of the feed line to the switching valve 1, and at a constant flow valve body 39 the diameters of a water through hole 40 becomes d1>d2 in response to an increase in the amount of feed water, which increase is caused by a rise in the pressure of feed water, so that the amount of feed water is automatically adjusted to a roughly constant rate regardless of the pressure of the feed water. |
