INJECTOR

The invention relates to an injector comprising an injector body (1) as well as a nozzle body (2) with a bore (4a) receiving a nozzle needle (5), wherein the nozzle needle (5) is translationally movable in the bore (4a), and has a nozzle needle tip (7) cooperating with a nozzle body seat (8), wherein at least one nozzle opening (9) is assigned to the nozzle body seat (8), which is controlled by the nozzle needle (5) and is connected to a high-pressure line (10, 10a) for a medium in the injector body (1) and the nozzle body (2), and wherein a piezoceramicsensor (17) is provided for recording a pressure profile of the medium. According to the invention, the injector body (1) is provided with a sensor (17) for determining a pressure profile of a medium guided through the injector body (1), the function of which is improved. This is achieved in that the sensor (17) is aligned with respect to the high-pressure line (10) and is installed into a recess (12) with simultaneous application of a preload applied by a clamping screw (20) on the sensor (17).
