摘要： A relief valve in particular for relieving the super-atmospheric pressure in a tank for combustible liquids and comprising a pilot valve unit (6) with an inlet opening (9) and an outlet opening (10). By a predetermined, adjustable super-atmospheric pressure in the tank, the pilot valve unit (6) opens and allows a gas flow from the inlet opening (9) to the outlet opening (10), which on the one hand boosts the valve to open quickly and, on the other, entails that a chamber (15) is evacuated of gas. The chamber (15) is closed by a membrane (3) which controls a valve body (2) towards or away from a valve seat (1) to the effect that it is possible to allow or block a flow of gas between a space (13) and a relief passage (5). According to the invention the relief passage (5) is open towards the open via an excess-pressure valve (11), and the outlet opening (10) of the pilot valve unit (6) is connected to the relief passage (5). By those measures an improved booster effect as well as a higher degree of safety that a fire cannot transplant from the outside and into the relief passage (5) and the cavity (13) are accomplished.
