Abstract

1. Shut-off device for liquids, particularly for gulleys, with a chamber (4) having at the top an inlet (5) and at the bottom an outlet with a shut-off means (12), the closure member (13) of which is yieldingly maintained in the closed position in order to yield before the ground pressure of a liquid, particularly water, in the chamber (4), characterised in that the closure member (13) which, when the chamber (4) is filled with this liquid, yields, before its level reaches the inlet (5) or an overflow (10) provided on the chamber (4), during filling with a liquid of lower density, particularly oil or petrol, remains in the closed position when the level thereof reaches or exceeds the inlet (5) or overflow (10).
