<p>Provided in succession in a flow passage from a shower side flow passage provided in a cock (1) to a shower head (3) or to a discharge end of the shower head (3) are pressure adjusting means for adjusting the pressure of a fluid supplied from an upstream side by throttling the flow passage, and flow rate adjusting means for adjusting the flow rate of the fluid supplied by the opening degree of the flow passage opened to the discharge end of the shower head (3). Further, pressure buffer means for buffering an increase of the pressure in the flow passage when the flow rate adjusting means closes the flow passage is included as a flow passage system capable of buffering an increase of pressure in the flow passage the flow rate adjusting means is operated. Accordingly, pressure rise caused by water hammer occurring particularly at the time of water stoppage is suppressed to reduce the pressure acting on respective elements including a shower hose (2), thus achieving improvement of the pressure resistance of the shower hose (2) and maintenance of the cock.</p> |
