Abstract: The present invention relates to an injector for injecting gas, in particular hydrogen, preferably for directly injecting hydrogen, comprising an injector housing for holding injector components, a valve needle movably arranged along its longitudinal axis in the injector housing and configured to selectively close or release an injection opening for the flow of hydrogen therethrough, and a valve, preferably a solenoid valve, which is adapted to transfer the valve needle into a closing or releasing state by a movement along its longitudinal axis. The injector is characterized in that the valve needle is a hollow needle adapted to pass a gas, in particular hydrogen, flowing through the injection port through the interior of the hollow needle.
