ABSTRACT:
An injection nozzle for use in a common-rail system includes a nozzle body with an actuator piston. In the closed condition of the nozzle the nozzle body bears against a seat and upstream of the seat delimits a nozzle chamber communicated with the high-pressure line of the common-rail system. A working chamber of the actuator piston is communicated with the high-pressure line by way of a feed throttle means, the active surface area of the actuator piston being larger than the surface area of the nozzle body which is effective in the nozzle chamber. A return line leads from the working chamber through a return valve. An actuating means is operated by an electrical signal for actuating the valve member of the return valve. The actuating means is a means which displaces the return valve member in analog relationship with the electrical signal so that the return valve forms in the return line a throttle of variable cross-section.
