摘要： Le dispositif de réglage hydraulique présente un cylindre à différentiel (11) dont l'espace annulaire (14) est toujours alimenté en pression par une pompe (16). La chambre de pression (18) en face de la grande surface du piston est reliée par une conduite de connexion (41) à la pompe. De cette conduite de connexion (41) part une dérivation menant à une soupape de commande (21). Cette soupape de commande est d'autre part en communication avec une conduite de retour (26). Par pilotage approprié de la soupape de commande il est possible de faire varier la pression dans la dérivation (19) et par conséquent dans les chambres de pression (14, 18) du cylindre à différentiel.

摘要： The invention relates to a dual nozzle (3) for injecting fuel and an additional fluid into a combustion chamber of an internal combustion engine, comprising a nozzle body (3.0) which has at least one admission bore (3.2) for supplying fuel into the dual nozzle, said fuel being at high pressure, and nozzle bores (3.8) for injecting fuel from the dual nozzle into the combustion chamber. The invention is characterised in that a preferably metal jacket (7) is arranged around the nozzle body. Said jacket (7) surrounds a hollow cavity (8) bordering at least the outer surface of the nozzle body, especially running around the nozzle body, for receiving an additional fluid, and in that a delivery line (5) for delivering the pressurised additional fluid to the hollow cavity and one or several injection nozzles for injecting additional fluid from the hollow cavity into the combustion chamber are provided. The fuel and the additional fluid are injected strictly separately so that it is impossible for the two fluids to mix before they reach the combustion chamber. The nozzle body and the especially the area of the nozzle dome are cooled by the additional fluid to be injected being guided outside which prevents the nozzle bores from coking. Only one magnetic valve is required in addition for measuring the quantity of fuel to be injected when using the inventive dual nozzle.

摘要： In fuel feeding piston pumps, there is a danger that the shaft bearing be affected by fuel entering the area of the shaft bearing. In the disclosed fuel pump (2), a separating space (20) is provided between the shaft bearing (14) and a fuel-containing chamber (16). The separating space (20) contains air, for example, as separating medium, and communicates with an air inlet of the internal combustion engine. This ensures that no fuel can escape into the area of the shaft bearing (14) nor outwards. This fuel pump is particularly suitable for internal combustion engines in which the fuel must be supplied under high pressure.

摘要： The electro-hydraulic adjusting device for actuating a device for moving at least one camshaft of an internal combustion engine in relation to its crankshaft has two differential pistons (42, 12), each of which serves to move a camshaft (inlet or outlet). A pump applies pressure to the small effective piston area (14, 40) of the two differential pistons (42, 12). To the pressure chambers (11, 44) at the larger effective piston area is allocated an independent pressure control valve (21, 46; 60) via which the pressure in said pressure chamber can be controlled independently of the other differential piston.

摘要： A fuel injection system with a common rail pressure accumulator (2) filled with fuel under high pressure and a binary nozzle (3) for injecting two fluids, a fluid fuel and an additional liquid, into an internal combustion engine, comprises a first 2/2-port valve (MV1) arranged in the injection line (6) between the common rail pressure accumulator (2) and a pressure chamber (3.5) that surrounds the needle (3.1) of the binary nozzle (3), and also a second 2/2-port valve (MV2) whose inlet is connected through a supply line (7) to the injection line (6) at a point located between the first 2/2-port valve (MV1) and the pressure chamber (3.5), and whose outlet is connected through a discharge line (8) to the fuel low pressure side. This makes it possible to replace the otherwise common, considerably more complex 3/2-port magnetic control valves by more cost-effective 2/2-port valves. At the same time, this makes it possible to use a single metering valve which actuates a whole group of injectors for metering the additional liquid.

摘要： The invention relates to an atomizing device for a gas/liquid mixture, especially for injecting the same into a chemical reformer used for producing hydrogen. The inventive atomizing device comprises at least one gas supply line for supplying a gas stream (11, 11a, 21) and at least one liquid supply line (16, 18) for supplying a liquid stream (17, 19). The liquid supply line (16, 18) opens at a discharge point (16a, 18a) into a venturi tube (12) located in the gas supply line.

摘要： The invention relates to a fuel injection system provided with a Common Rail (2) pressure accumulator filled at high pressure and with a multifuel nozzle (3) for bifluid injection of fuel and an adjunctive liquid into an internal combustion engine. The inventive injection system comprises a first 2/2-way valve (MV1) in the injection pipe (6) between the Common Rail pressure accumulator (2) and a pressure chamber (3.5) surrounding the injector pin of the multifuel nozzle, as well as a second 2/2-way valve (MV2), the inlet of which is connected via a supply pipe (7) to the injection line (6) at a point located between the first 2/2-way valve (MV1) and the pressure chamber (3.5), and the outlet of which is connected via a discharge line (8) to the low pressure side of fuel. It is thus possible to replace the usual valves, technicaly much more expensive, i.e. the magnetically operated 3/2-way valves, by 2/2-way valves, which are more economical. The invention also enables the adjunctive liquid dosage to be transferred to a regulating valve which operates a whole series of injectors.
