Abstract
A fuel injector (1), especially a fuel injector (1) for injection systems of internal combustion engines, includes a solenoid which works together with an armature and a valve needle (15) to actuate a valve-closure member (22), which together with a valve-seat surface (24) forms a sealing seat. A longitudinal axis (28) of the valve needle (15) is inclined by a prescribed angle (γ) with respect to a longitudinal axis (29) of a valve housing (11). The armature is linked with an actuating body (12) whose longitudinal axis (29) is inclined with respect to the longitudinal axis (28) of the valve needle (15) and which acts on the valve needle (15) through a hydraulic device (13).
Claims11
A fuel injector (1), in particular an injector for fuel injection systems of internal combustion engines, having an excitable actuator and a valve needle (15) to actuate a valve-closure member (22), which, together with a valve-seat surface (24), forms a sealing seat;
- a longitudinal axis (28) of the valve needle (15) being inclined at a predefined angle (γ) to a longitudinal axis (29) of a valve housing (11), wherein the armature (4) is linked to an actuating body (12) whose longitudinal axis (29) is inclined with respect to the longitudinal axis (28) of the valve needle (15), and the actuating body (12) acts on the valve needle (15) through a hydraulic device (13).
