Title: FLUID INJECTOR FOR A MOTOR VEHICLE
Abstract:
A fluid injector (1) for a motor vehicle comprises an actuator (3), a nozzle needle (9) and a valve plate (30) which has a first and a second recess (31, 32), which forms a hydraulic coupling between the actuator (3) and the nozzle needle (9). The fluid injector (1) also comprises a control valve (20) and a pressure-regulating valve (10), part of which is arranged in the valve plate (30) and which, in a first state, closes a cut-off channel (14) in the valve plate (30) and prevents fluid flowing through the cut-off channel (14) and, in a second state, allows fluid to flow through the cut-off channel (14). A fluid pressure in the fluid injector (1) can be regulated in this manner by means of the pressure-regulating valve (10) interacting with the actuator (3).
