摘要:
An electrically actuatable fuel-injection valve for internal combustion engines has a piezoelectric hollow-cylindrical radial vibrator (11) within the wall (30) of which a number of continuous fuel-receiving chambers (12, 12') are arranged parallel and concentric to a longitudinal axis (19) of the radial vibrator. Each of the chambers (12, 12') is in communication at one open end with a fuel feed path and at its other open end has an ejection opening in the form of a bore (27, 27'). A passage line (passage bore 29) for a stream of air which conducts at least a part of the stream of intake air is conducted through the radial vibrator (11) concentrically to the longitudinal axis of the radial vibrator. The passage line terminates, open, approximately at the level of the injection openings.
