摘要： A fuel injector for an internal combustion engine, with a control chamber contained in an injector housing and acted on with highly pressurized fuel via a permanently acting inlet throttle in an inlet from a high-pressure accumulator. A nozzle needle/tappet device protrudes into this control chamber and is actuated in a movement directed (10) by the pressure decrease or pressure increase in the control chamber a pressure relief in the control chamber being produced by means of a multi-way valve activated by an actuator. The valve chamber of the multi-way valve and the control chamber in the injector housing are connected to each other by means of two conduits, one of which is closed when the multi-way valve is in a second switched position and is open when the multi-way valve is in a middle position.

摘要： A piezoelectric element for actuating a mechanical component, is proposed in which, with a multilayer structure of piezoelectric layers, the inner electrodes disposed between them can be subjected to an electrical voltage. Since the piezoelectric layers with the inner electrodes function like capacitors, a shunting resistor for a requisite electrical discharge is formed, preferably in the head or foot part, by forming resistor tracks out of a resistor layer.

摘要： A fuel injection valve for internal combustion engines having a valve body in which a bore is embodied, a valve seat face, at least one injection opening embodied on the end toward the combustion chamber of the bore, and at least one injection opening connecting the bore with the combustion chamber of the engine. A nozzle needle is longitudinally displaceably guided in the bore and on its end toward the combustion chamber it has a sealing face, which cooperates with the valve seat face and thus controls the at least one injection opening. The nozzle needle has a central longitudinal bore, in which an inner needle is disposed that is fixed immovably relative to the valve body. The nozzle needle is guided over at least part of its length on the inner needle, so that the nozzle needle is kept exactly centrally in the bore at all times.

摘要： An injection nozzle has a nozzle body, a nozzle needle that is supported displaceably in the nozzle body, a control chamber that communicates with a fluid inlet and a fluid outlet, and a valve element that can open and close the fluid outlet. The control chamber is laterally defined by a displaceable ring which rests on the nozzle needle, and a closing spring presses the ring against the nozzle needle in fluid-tight fashion.

摘要： The invention is based on a hydraulic control device (60), in particular for an injector (16) of a fuel injection system (10) in motor vehicles. Known control devices have a piezoelectric actuator, which controls a multi-position valve (75), embodied as an outward-opening valve with a valve member (74) guided in a valve bore (76). According to the invention, it is proposed that a booster (62) that reverses the deflection motion of the actuator (52) be disposed between the actuator (52) and the valve member (74), and that the multi-position valve (75) be embodied as an inward-opening 3/2-way valve. The valve member (74) of this valve, in operative connection with a valve seat (98) and a control edge (96), alternatingly opens or closes pressure fluid connections between pressure fluid conduits (86, 88, 92).

摘要： The invention relates to an injector for injecting fuel into combustion chambers of an internal combustion engine. A control part is provided in the housing of the injector and protrudes into a control chamber, in which a control volume is enclosed. The control chamber can be pressure-relieved via an actuator. In the housing of the injector body, the control part is acted upon by spring elements. The control part is guided in a guide sleeve that defines the control chamber.
