Fuel injection device for internal combustion engines

A fuel injection device for an internal combustion engine having a fuel supply tank, a fuel feed pump (1) that pumps fuel from said fuel supply tank to a high-pressure reservoir (16) said high reservoir communicates with a reservoir chamber (38) via a first electrically controlled valve (45) which is electrically controlled by a control unit (75), for pre-storing a fuel injection quantity in said reservoir chamber (38), said reservoir chamber as defined by a movable wall (37) that is adjustable counter to a restoring force (63), and, via a second electrically controlled valve (52) electrically controlled by said control unit (75), said reservoir chamber (38) can be made to communicate with a fuel injection valve (25) via a connecting line (24), under the influence of the restoring force and with said first electrically controlled valve (45) closed, said reservoir chamber (38) can be evacuated toward the fuel injection valve (25), also associated with the adjustable wall (37) is a travel transducer (68) which generates a signal corresponding to the deflection travel of the adjustable wall (37) counter to the restoring force, which signal is connected to the control device (75), said control device (75) includes a comparison device for comparing the signal of the travel transducer with a set-point value formed as a function of operating parameters, and when the set-point value is attained the first electrically controlled valve (45) is closed once again whereby the filling of the reservoir chamber (38) in intervals is controlled by the triggering of the first electrically controlled valve (45).
