Abstract

A deventilating device for motor vehicles is disclosed. The deventilating device allows, in the fuel tank and connected system parts, a limited overpressure which, on the one hand, is safe and, on the other hand, affords the possibility of checking the tightness of the system by on-board means specific to the vehicle.
