INJECTOR FOR INJECTING GAS

The present invention relates to an injector for injecting gas, preferably for directly injecting hydrogen, comprising a fuel feed line for introducing a gaseous fuel which is under high pressure, an actively switchable active valve, preferably an active solenoid valve, which is designed to take up a closing or a releasing state in order either to permit or to interrupt a flow connection from the fuel feed line to a region downstream of the active valve, and a passive valve which is arranged downstream of the active valve and is passively switchable by different pressure ratios prevailing upstream and downstream into a closing or releasing state and/or can be brought into a closing or releasing state by contact with a movable part of the active valve. In a closed state of the active valve, at least one sealing surface of the active valve is sealed.
