Date Feb. 6, 1992.A tank vent valve for the metered admixing of volatilized fuel to the fuel/air mixture of an internal combustion engine has a valve housing with inflow and outflow sockets, between which is arranged an electromagnetically operable seated valve, which is spring loaded in the closing direction by a valve closing spring. For the simple design of the tank valve, the valve opening of the seat is arranged as a ring gap nozzle in the return yoke of the electromagnet, and the valve double seat which acts in conjunction with the valve member and which surrounds the ring gap nozzle is arranged on that side of the return yoke which faces the inflow socket. For setting the stroke of the valve member, the hollow cylindrical magnet core of the magnet housing can be threaded by means of an adjusting thread in the magnet housing. Supported on the magnet core is a valve closing spring, which loads the valve member which is formed by the armature of the electromagnet, in the closing direction.</p> |
