摘要： A valve for controlling fluids, which is provided with a fluid-filled coupling chamber that is disposed between an actuator piston of a piezoelectric actuator and a piston that actuates a valve member. In order to compensate for a leakage in the coupling chamber that is intermittently under high pressure during a switching procedure, a filling valve is provided that is disposed radially on the coupling chamber, but outside the chamber, and this valve monitors an inflow from an inlet conduit that is under ambient pressure in the valve. In this manner, on the one hand, the clearance volume produced by the attachment of the filling valve is very small and on the other hand, the filling valve is independent of the accelerated movements of the pistons, i.e., independent of their acceleration forces. The valve is designated for use in fuel injection devices for internal combustion engines of motor vehicles.

摘要： The invention relates to a device for actuating a control piston or nozzle needle (27) via a control chamber (26). The control chamber communicates via a control chamber line (25) with valve chambers (3, 22) of a 3/2-way valve (5). The valve body (6, 40, 51) of this valve is switchable by means of an actuator (11). By means of a restoring spring (14), the valve body (6, 40, 51) is acted upon such that a seat portion (7), embodied in the housing (4) on the valve body (6, 40, 51), is put into its valve seat (20). The valve body (6, 40, 51) of the 3/2-way valve (5) has a seat portion (7) and a longitudinal slide portion (8), as well as hydraulic faces (31,32), facing one another, that make the state of pressure equilibrium of the valve body (6, 40, 51) possible. The valve body (6, 40, 51) is moved to different stroke lengths (10; 23, 24) by means of an actuator (11).

摘要： A device is proposed for measuring the composition of fluids, in particular of constituents of exhaust gases from internal combustion engines, in which a light ray (32, 31) is used to irradiate the exhaust gas to be measured over the length of a measuring section (29) and is weakened or changed more or less, depending on the content of constituents. The light signal being received is advantageously registered by a measured length light receiver (18) which is shielded light-tight against the light emitting light source (14) and is evaluated in relation to the original light emission, in an evaluation circuit (26). In this simple way, accurate information is obtained of the exhaust gas clouding and of the loading of a fluid or gas with constituents which are optically active.

摘要： An apparatus for measuring particulate matter in a flue gas or exhaust gas of a combustion process comprising means for transmitting a beam of light between an optical transmitter and an optical receiver. The light passes through two diametrically opposed light slits closed by transparent bodies in the wall of the tail pipe and crosses through a flow of exhaust gas carried in the tail pipe. The attenuation of intensity of the light beam is a measure of the particulate matter. When the measuring apparatus is used to measure a soot concentration in an exhaust gas of internal combustion engines of a vehicle, it is mounted directly on the tail pipe, and the transparent bodies are heated in the vicinity of the faces acted upon by the exhaust gas flow to a temperature above the soot burn-off temperature. As a result, adulteration of the measured value by soot deposits in the measurement path to the transparent bodies is prevented, and continuous operation of the measuring apparatus is assured.

摘要： A fuel injection valve for internal combustion engines, having a valve member which is axially displaceable in a bore of a valve body and which on an end toward the combustion chamber has a valve member head. The head forms a valve closing member, which on one side toward the valve body has a sealing face, with which the sealing face cooperates with a valve seat face provided on the face end of the valve body toward the combustion chamber. An injection opening in the valve member head, which emerges from a pressure chamber, formed between the valve member and the wall of the bore, and leads away along the circumferential wall of the valve member head. The injection opening is closed by the wall of the bore when the valve member is resting on the valve seat and is opened by an outward-oriented opening stroke motion of the valve member. The valve member is actuatable by an externally controllable actuator independently of the high fuel pressure in the pressure chamber, and two pressure shoulders, facing one another and axially defining the pressure chamber, are provided on the needle-like valve member and each have substantially equal pressure engagement surface area. The pressure chamber is characterized in that one of the pressure shoulders is disposed on an end remote from the combustion chamber of the valve body, in a compensation chamber which communicates fluidically with the pressure chamber and is closed off on a face end by an axially displaceably guided pressure sleeve.

摘要： A valve for controlling fluids, which in order to be actuated, cooperates with a fluid-filled membrane actuator. A coupling chamber provided in the membrane actuator is sealed by two membranes as dividing walls. In order to compensate for fluid losses produced by pressure acting on the membrane actuator, a filling valve is provided, which is disposed in the region of one of the two membranes. A refilling of the membrane actuator during the closed phase of the control valve is assured by way of the filling valve. A filling of this kind can also compensate for length changes of the piezoelectric actuator, the valve, or the valve housing. The valve is designated for use in fuel injection devices for internal combustion engines of motor vehicles.

摘要： A fuel device including a high-pressure fuel source from which fuel is supplied to fuel injection valves. The fuel injection valves are controlled with the aid of a valve that is driven by a piezoelectric or magnetostrictive drive mechanism. With the aid of this drive mechanism, a 3-way valve having a closing body can be adjusted in an intermediary position in which a control chamber, by way of which a hydraulic force can be exerted in the closing direction on a valve closing member of the injection valve, can simultaneously be connected to a high-pressure fuel source and a relief chamber in order to adjust a control pressure that lies between the high pressure of the high-pressure source and a relief pressure. In this manner, a partial opening of the injection valve member of the injection valve can be adjusted in order to introduce a reduced injection quantity into the combustion chamber of the internal combustion engine.

摘要： A valve for controlling liquids which for its actuation is provided with a liquid-filled coupling chamber, which is disposed between an actuator piston of a piezoelectric actuator and a piston that actuates a valve member. To compensate for liquid losses suffered by the coupling chamber, which is briefly at high in each work cycle, the pressure difference that exists during the return stroke of the actuator piston between the coupling chamber and the opposite sides of the actuator piston and of the that actuates the valve member that are remote from the coupling chamber is utilized to achieve refilling in valveless fashion along gaps. The valve is used for use in fuel injection systems for internal combustion engines of motor vehicles.

摘要： A fuel injection system for internal combustion engines is proposed which supplies fuel injection valves with fuel from a high-pressure fuel source, under the control of a control unit. The fuel injection valve has an injection valve member, whose opening or closing position is determined by a pressure that acts upon this injection valve member and that is set in a control chamber. To that end, to perform an injection, the pressure in the control chamber must be relieved; which is achieved with a control valve that opens two different outflow cross sections of an outflow conduit of the control chamber in succession. This makes it possible to accomplish an adapted opening of the fuel injection valve member for a preinjection and for a main injection.
