Abstract: An injector is provided to inject an aqueous urea solution into an exhaust line. The injector comprises a single fluid inlet, an injection passage, fluidly connecting the inlet to the injection port, and a shut-off device for the injection port. The shut-off device further comprises an actuator that is configured to selectively move a shutter between open and closed positions. A cooling passage is fluidly connected to the injection passage and is configured to cool the actuator. A fluid pressure regulator is interposed in the cooling passage.
