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 device for measuring particle emissions of an internal combustion engine, in particular the soot concentration in the exhaust gas, has a signal transmission route, located between a transmitter and a receiver, which traverses a flow of exhaust gas carried in an exhaust gas tube of the engine. To avoid soiling of the active elements of the transmitter and receiver that would cause inaccuracies in measurement, the signal transmission route is embodied as a beam of light, which passes through two diametrically opposed openings in the wall of the exhaust tube. The light-admitting openings are each closed with a respective transparent disk. The disks are heatable and are heated to a temperature above the burnoff temperature of the particles. Appropriate light emitting and receiving elements are used in combination with appropriate heating and evaluation circuits which indicate the soot concentration and which control fuel input to change the soot concentration.

摘要： A valve control unit for a fuel injection valve, has a housing body, in which two valve control chambers that communicate continuously with one another are provided. The first valve control chamber communicates fuel with an inflow conduit for fuel pressure on a terminal member of a valve control piston which is displaceable in the housing body and the second valve control chamber communicates with a closable outlet conduit. A mechanical stop for limiting the mobility of the valve control piston in the direction of the second valve control chamber is embodied on the housing body. The quantity of preinjected fuel can be minimized by the volume of fuel in the first valve control chamber.

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).
