Gas injector including lift dethrottling

An injector system, comprising:

• a gas injector for injecting a gaseous fuel into a combustion chamber;
• and
• a cylinder head having a cylinder head opening in which the gas injector is situated, an end of the gas injector facing the combustion chamber being situated in the axial direction at a predetermined distance from an end of the cylinder head opening on the combustion chamber side,
• wherein the gas injector injects a gaseous fuel directly into the combustion chamber, the gas injector including a valve closing element for opening or closing a pass-through opening, a valve body, and a sealing seat between the valve body and the valve closing element, wherein in the case of a maximum lift of the valve closing element, a first flow cross section between the valve body and the valve closing element is smaller in a flow direction upstream from the sealing seat than a second flow cross section between the valve closing element and the sealing seat and is smaller than a third flow cross section in the flow direction downstream from the sealing seat.
