<p>PURPOSE: To select accurately and quickly appropriate flow speed, by providing a housing with at least two valves where each valve relates to the own flow route. CONSTITUTION: This equipment is placed in a flow rate limiting flow route 140 which communicates with a cavity 162 by flowing liquid through a filter hole 130. End of the flow route 140 is a downstream end 150 and a plurality of holes 172, 174, 176, 178, 180 and 182 are placed between a filter hole 130 and the downstream end 150. Any one of these holes 172, 174, 176, 178, 180 and 182 is connected selectively to a fluid. The holes 172, 174, 176, 178 and 182 are located in a previously selected distance along a flow route 140 and are located along the distance of the low flow speed route 140 to correspond to the predetermined flow speed. Accordingly, this can be applied for various many states requesting the own flow speed.</p> |
