    • A device for injecting fuel into a combustion chamber of an internal combustion engine, having a glow coil (22, 92) disposed on the outlet side of the injection nozzle and increasing in size conically toward the combustion chamber; the coil is surrounded by a sleeve (30, 96) which firmly holds the end turn (88, 93) of the glow coil (22, 92) toward the combustion chamber and has a contact ring washer (46, 98), on which the other end turn (86, 94) of the glow coil (22, 92) is secured. The end turn (88, 93) toward the combustion chamber rests on an annular shoulder (90, 107), oriented according to the invention toward the combustion chamber, of the sleeve (30, 96), which surrounds an insertion opening (91, 106) the inside diameter of which is smaller than the outside diameter of the end turn (88, 93) toward the combustion chamber, but greater than the outside diameters of all the other turns of the glow element (22, 92). As a result, the glow coil (22, 92 ) can still be inserted and electrically contacted once the contact ring washer (46, 98) has already been fastened to the sleeve (30, 96) and with it forms a pre-fabricated structural unit.

    • A fuel injection nozzle for internal combustion engines includes a glow element connected to the outlet side of the injection port, the glow element being integrated into the clamping nut which braces the nozzle body with the nozzle holder. Downstream of the nozzle body, the clamping nut has a support shoulder, on which a sleeve surrounding and carrying the glow element rests. The glow element is formed by a jacket heating conductor, shaped into a dimensionally stable coil which is electrically connected with the contact element and with the sleeve. The connection end of the jacket heating conductor may be formed as a so-called cold end, as a result of which the adjoining parts are thermally relieved.

    • A fuel injection pump for internal combustion engines having a hydraulic control mechanism includes a control cylinder with a control piston actuating a control member, a hydraulic work chamber and one switching valve each for an input and an output controlled by a valve control unit. The inflow to and return from the work chamber is provided with the control valves in order to shut down the engine upon a shutoff or a malfunction in the hydraulic control mechanism. The fuel feed pump is electrically driven, and the hydraulic work chamber communicates with the fuel tank via a relief device. The supply of current to the valve control unit and the feed pump is switched on and off, along with the rest of the current supply to the engine, via a driving switch. Additionally, the valve control unit is embodied such that upon the appearance of a persistent control deviation of the control member, the valve control unit shuts off the feed pump. The relief device includes various variant embodiments operative upon shutoff of the current supply or the occurrence of a malfunction and enables the restoration of the control mechanism to its zero or stopping position.

    • The invention relates to an electrically controlled injection system for internal combustion engines, in which a magnet valve that is open when without current is used to control the fuel quantity of a high-pressure chamber in the injection pump. A pressure chamber communicates via a pressure conduit directly with the pump work chamber of the high-pressure pump, and a connection from the pressure chamber to a diversion chamber is controlled by a movable valve member via a valve seat. A diversion bore, and a pressure equalization piston is disposed on the valve member, via a neck, on a side remote from the magnet, so that approximately the same pressure as on the magnet side of the movable valve member prevails on the face end of this pressure equalization piston. The chambers on both face ends of the valve member communicate with one another through a connecting conduit, and a further connecting conduit leads from the magnet chamber to a leakage chamber. In one feature of the invention, first and second throttles are disposed upstream of the face end chamber and at the end of the connecting conduit, so that the valve member is embedded in a hydraulic column of equal pressure.
