"textContent": "A fuel injector including a flow balanced injector needle seal is provided. The fuel injector includes a needle in a fuel passage of the fuel injector body. The needle moves longitudinally in the fuel passage to selectively stop and start fuel injection from the fuel passage. The fuel injector includes a check valve assembly that maintains pressurized fuel in the fuel passage and permits fuel flow out of the fuel passage in response to a fuel injection event. The needle seal is provided between the check valve assembly and a sleeve that extends around the proximal end of the needle. The needle seal includes multiple inlet orifices for receiving a fuel flow into the needle seal that are positioned relative to one another so that net lateral forces on the needle are effectively offset from one another.",
