VALVE FOR METERING A FLUID
DRIVE
March 15, 2017
A valve (1) for metering a fluid, which serves in particular as a fuel injection valve for internal combustion engines, comprises an electromagnetic actuator (2) and a valve needle (7) that can be actuated by means of an armature (4) of the actuator (2). The armature (4) is movably guided on the valve needle (7). Furthermore, a spring element (28) is provided which acts upon the armature (4) at least by means of a spring force transmission means (20, 60) connected to the armature (4) against a stop element (9, 10) which is arranged on the valve needle (7) in a fixed position with respect to the valve needle (7). The spring element (28) is clamped radially on one side with the armature (4) or the spring force transmission means (20, 60) and on the other side radially with the stop element (9, 10). In this way, a play-free rotational fixing of the armature (4) is achievable.
