Abstract
An injector for an injection system of an internal combustion engine, with an injector head (1), a nozzle (13) for injecting fuel, a control unit (12) for controlling the transfer of fuel from the injector head (1) to the nozzle (13) and an actuator (6) for the mechanical activation of the control unit (12) in order to control fuel injection, an injector housing (2), which receives at least the control unit (12), being integrally formed on the injector head (1) at the bottom.
Claims9
An injector for an injection system of an internal combustion engine, comprising an injector head, a nozzle for injecting fuel into a combustion space in the internal combustion engine, a control unit for controlling the transfer of fuel from the injector head to the nozzle and an actuator for the mechanical activation of the control unit in order to control fuel injection, further comprising an injector housing, for housing at least the control unit, said housing being integrally formed in one piece on the injector head, and wherein the actuator acts directly on a valve piston such that contacting surfaces of the actuator and valve piston retain a liquid film there between during a switching operation.
