Title: Valve for the metered addition of volatilised fuel to the fuel-air mixture of an internal combustion engine
Inventor: FEHRENBACH SIEGFRIED
IPC: F02M25/08
Filed: 1988-12-28
Abstract: A tank venting valve for the metered addition of volatilised fuel to the fuel-air mixture of an internal combustion engine has a valve housing (10) with admission and outlet fittings (11, 12), between which a solenoid-actuated seat valve (17) is arranged. A lift-adjusting device adjusts the lift of the valve element (16) of the seat valve (17) in such a way that the lift is at a minimum when the internal combustion engine is idling and at a maximum at full load. In order to achieve a closed seat valve (17) without any flow, the valve element (16) is loaded by a valve closing spring (23) and the lift adjusting device is designed so that a movable lift stop (56) for the valve element (16) is connected to an actuating element (26), subjected on one side to the pressure on the outlet fitting (12) and on the other to the ambient pressure, in such a way that the lift stop (56) is displaced in the direction of the valve element (16) as the pressure differential increases (Fig. 1). <IMAGE>
