ABSTRACT OF THE DISCLOSURE An arrangement for regulating the flow of a gaseous medium in a conduit includes a flap valve pivotably mounted in the conduit and biased by a spring toward its open position and by the pressure of the gaseous medium flowing through the conduit toward its closing position. A rod-shaped member is pivotally mounted on one section of the flap valve, and a sleeve-shaped member is pivotally mounted on a plate-shaped element rigid with the conduit and extending axially thereof downstream of the flap valve. The sleeve-shaped member has a passage therein in which the rod-shaped member is received with play so that, upon rapid movement of the rod-shaped member in the passage, the sleeve- shaped member is entrained by friction on pivots, thus seizing the rod-shaped member. In this manner, the flap valve is prevented from fluttering, while its responsiveness to gradual pressure changes of the gaseous medium is unaffected.
