Summary:PROBLEM TO BE SOLVED: To provide a constant flow rate valve, capable of stabilizing flow characteristics. SOLUTION: The constant flow rate valve 1 includes a conically shaped coil spring 2 that forms a valve element, and a casing 4 which forms a flow passage 3 of fluid and houses the coil spring 2 within the flow passage 3 so that a minor diameter end 21 of the coil spring 2 is turned to the upstream side of the flow passage 3. The casing 4 includes a fixing part 43 for fixing at least a part of the outermost circumferential part of a major diameter end 22 of the coil spring 2. COPYRIGHT: (C)2010,JPO&INPIT
