Fuel injection valve, pilot control valve therefor, and method for its assembly |
摘要 |
A pilot control valve of a fuel injection valve, having a first housing part which forms a well with walls parallel to an axis (z-z). A second housing part with a plug-in portion which is introduced in form-locking fashion into the well up to a set-point position. The first and second housing parts jointly define a chamber in which a valve closing member is displaceable along the axis in a chamber between a closed position, in which the valve closing member rests on a pilot control valve seat, and an open position, and the stroke of the valve closing member between the closed and the open positions is defined by the set-point position. The plug-in portion is fixed in the set-point position on the walls of the well that are parallel to the axis (z-z). It is thus possible for the set-point position, which is equivalent to a desired switching performance of the pilot control valve, to be adjusted accurately before a fixation.
