ABSTRACT:
In a conventional relief valve having a valve element supported by a diaphragm, since a surface of the valve element exposed to pressure is large and an opening/closing operation of the valve element is rapidly conducted, the operation often leads to chattering and is therefore poor in stability. A relief valve of the invention is free from chattering and capable of smoothly performing the opening/closing operation of its valve element (7). The element (7) is adapted to open and close a fluid passage and disposed between: an inlet port (2) in direct communication with an upstream-side fluid passage (1); and, an outlet port (4) in direct communication with a downstream-side fluid passage (3), and is provided with a flange (8) in its upper portion. Mounted on the flange (8) is a sleeve-like bellows (6) for supporting the valve element (7).
