摘要： A gas metering valve for an internal combustion engine. The gas metering valve includes a housing in which a gas chamber is formed, which includes an inlet opening and an outlet opening. A movable valve element is situated in the gas chamber, which is movable by an electrical actuator against the force of a return spring and which cooperates with a valve seat for opening and closing the inlet opening. A blocking valve is situated between the valve element and the outlet opening, which opens in the flow direction to the outlet opening and blocks in the opposite flow direction.

The method is characterised by the following steps: a. applying (60) the initial electrical current strength to the solenoid (10); b. determining (61) the pressure p0 in the tank (2) and determining (61) the pressure p1 in the feed line (29) between the valve device (100) and the flow-regulating element (27); c. determining (62) the difference between the pressure p0 in the tank (2) and the pressure p1 in the feed line (29) between the valve device (100) and the flow-regulating element (27); d. assigning the determined difference between the pressure p0 in the tank (2) and the pressure p1 in the feed line (29) between the valve device (100) and the flow-regulating element (27) to one of the reference pressure differences (70) in the characteristic map (80) such that,—if the determined difference between the pressure p0 in the tank (2) and the pressure p1 in the feed line (29) between the valve device (100) and the flow-regulating element (27) can be assigned to one of the reference pressure differences (70): i. selecting (64) an electrical current strength assigned to the determined reference pressure difference (70) for the solenoid (10); ii. applying (65) the selected electrical current strength to the solenoid (10); iii. cyclically repeating (66) steps a. to d.; —if the determined difference between the pressure p0 in the tank (2) and the pressure p1 in the feed line (29) between the valve device (100) and the flow-regulating element (27) cannot be assigned to one of the reference pressure differences (70): returning (67) to step a.

摘要： The invention relates to a valve device (100) for a gaseous medium, in particular hydrogen, comprising a valve housing (6) and a solenoid armature (14) which is arranged in the valve housing and can move along the longitudinal axis (18) and which interacts with a first sealing seat (32) in order to open and close an outlet opening (40). Furthermore, the valve housing (6) is equipped with a second solenoid armature (16) which can be moved along the longitudinal axis (18) and which is at least partly received in a recess (38) of the first solenoid armature (14), and the second solenoid armature (16) interacts with a second sealing seat (34) in order to open and close an outlet opening (20) formed in the first solenoid armature (14). The first solenoid armature (14) and the second solenoid armature (16) are additionally surrounded by a magnet device (11), by means of which the first solenoid armature (14) and the second solenoid armature (16) can be moved along the longitudinal axis (18) using precisely one solenoid (10).
