摘要： The fuel injector comprises a control module, with a piston guide extending downwards, in which a control piston is arranged. The fuel injector further comprises a nozzle body, with a top surface on which the control module is mounted. The nozzle body comprises a drilling with a nozzle needle, co-operating with the control piston, arranged in the lower section thereof and the piston guide, arranged in the upper section thereof. A high pressure inlet is arranged in the control module and opens out into the drilling at the top surface. The drilling is embodied such that, on lifting the nozzle needle from the valve seat thereof, the fuel which escapes from the fuel injector is replaced, whereby fuel from the high pressure inlet flows through the drilling in the direction of the valve seat.

摘要： An actuator (1) acts as a drive unit for an injector, especially for an accumulator injection system. The actuator comprises a piezostack (3) disposed in a tube spring, a top plate (2) and a bottom plate. The top plate (2) of the actuator is directly fixed to the injector housing (7) by means of caulked areas. The caulking enables the injector to be produced in a simple and economical manner.

摘要： A control module (1) for an injector of an accumulator injection system is used to control and guide a valve body (8). The control module comprises a high pressure supply line (2) for supplying fuel, and a guiding device (3) for guiding the valve body (8). A control room (4), an inlet throttle (5) and an outlet throttle (6) are also provided. The inlet throttle (5) connects the high pressure supply line (2) to the control chamber (4) and the outlet throttle (6) connects the control chamber (4) to a control valve (15). A control piston (7) is arranged in the control chamber (4), the end of the control piston opposite the control chamber (4) being connected to a high pressure region (9) on the valve body (8).
