Vent valve (1) for controlling the internal tank pressure of a fuel tank, having at least one valve housing (2) having at least one first connection (3) to the fuel tank and at least one second connection (4), which can be connected to a vent line leading to a fuel vapour filter, having at least one valve element (9), which is held in a valve seat (8) in a position in which it closes the first connection (3) by the force of gravity and/or by spring loading and, after a given pressure threshold is exceeded, is raised from the valve seat (8) and, when a given pressure threshold is undershot, returns to the initial position, wherein the valve element is arranged so that it can move within a valve element guide, the valve element has at least one first relief opening (10), which forms a bypass for a gap flow which arises during a return movement of the valve element characterized in that the valve element (9) has at least one second relief opening (14), which is closed by means of a nonreturn valve acting counter to the direction of closing of the vent valve (1) or which is open permanently in order to obtain forced leakage.
