摘要： A hydraulic injection-adjusting device for high pressure injection installations in auto-igniting internal combustion engines. Oil is supplied to operating chambers of the injection-adjusting device by means of a pressure supply pump with an electrically actuatable regulating valve being provided for controlling the flow of oil to inlet of the operating chambers. An electronic control unit is supplied on an input side which signals corresponding to current engine operating parameters with the control unit yielding on an output side thereof a desired value for the regulating valve to apply pressure in a controlled fashion to the injection-adjusting device. An arrangement is provided for measuring the actual value of the adjustment angle at the injection-adjusting device by constant answer-back line provides a feed of the actual value to the control unit. A control unit, depending on whether the desired value is larger with respect to the actual value or whether the actual value is larger than the desired value, yields a first and second signal of a defined magnitude. A regulating valve is constructed as an electromagnetically operated three-way or three-position valve for regulation of pressure supply, and pressure relief, with the regulating valve being capable of providing a control function when the valve is in a closed position.

摘要： A choke pin nozzle for diesel engines in which the choke pin is arranged on a nozzle needle. The nozzle needle is axially guided in a fitted bore in a nozzle body and is braced, through a separate spring plate, on a helicoidal compression spring disposed in a spring chamber or cavity of the nozzle. The spring plate is formed as a component of an intermediate piston which is connected on the nozzle side and guided axially with a seal in a portion of the nozzle. An escape or discharge bore is provided in the intermediate nozzle with the bore opening into the spring cavity. The piston is of a smaller diameter than the nozzle needle. The intermediate piston includes a bearing face which is cooperable with an upper sealing surface of the nozzle needle. A guide bore of the intermediate piston is widened in a stroke zone of the bearing face at least to a diameter of the fitted bore in which the nozzle needle is axially guided.

摘要： An electronically regulated fuel injection system for an internal combustion engine with a switchable safety and emergency driving device has a mechanical coupling which mechanically couples the accelerator pedal to the regulator. This coupling operatively interferes with a mechanical connection between a controller and the final control element that determines the quantity of fuel to be injected, after a fault signal has been outputted by a signal processing unit to a switchover element, which switches over control of the final control element to the simple regulator.
