摘要： In a fuel injection valve, the direct attachment of a protective sleeve to the valve housing has the effect that breathing of the inside of the valve can take place without spray water or other fluids penetrating into the inside of the valve (coil space). The fluid is, rather, held in a space with many passages. Corrosion on the contact pins or on the coil wire is, therefore, ruled out. The fuel injection valve is particularly suitable for use in fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.

摘要： An attachment of a fuel injection valve is formed at least from the main body and the insert which bound the gas supply passages between them and direct the gas in a metered and targeted manner onto the sprayed fuel. The attachment makes it possible to separate the functions of gas supply and metering from those of sealing the fuel injection valve against an induction conduit and fastening the attachment on the fuel injection valve. Furthermore, the design configuration results in a large number of variants which can be achieved by very simple and low-cost exchangeability of parts by virtue of the modularity of the system. The fuel injection valve is particularly suitable for fuel injection systems of mixture compressing internal combustion engines with external ignition supply.

摘要： A fuel injection valve including a pan-shaped protective cap having a radially outwardly extending recess which, together with the fuel injection valve, forms a gap which is so narrow that it exerts a capillary effect on the fuel so that, when the internal combustion engine is shut down, the high boiling point constituents of the fuel are deposited at the radial outer edge of the gap, because of the capillary effect, and the injection openings remain free from deposits. The protective cap of the invention has at least three protrusions formed from its bottom and protruding in the direction of the fuel injection valve to a predetermined axial distance, the protrusions of the protective cap being in contact with the orifice plate of the fuel injection valve, forming an axial gap in a simple manner between the bottom and the orifice plate. The protective cap can be used with fuel injection valves of various types.

摘要： The gas distributor apparatus has a common gas-supply line for supplying gas to a plurality of devices, e.g., arranged in series, the gas-supply line representing a substructure with an inner supply orifice and connecting pieces, which conform in number to the devices for injecting a fuel-gas mixture, and which extend in a normal direction starting from the gas-supply line and contain branched-off ports that communicate directly with the supply orifice. A permanent connection is established between the gas distributor apparatus and the devices in that gas-intake ducts are configured on the gas-containing bodies at least partially surrounding the devices, the gas-intake ducts having functional elements and projecting with these elements into the connecting pieces of the gas distributor apparatus. The gas is made available simultaneously for all devices in the supply orifice and then flows in each case via one connecting piece to a device. Thus, the gas distributor device represents a very compact assembly, which is very simple to assemble and disassemble. The gas distributor device is especially suited for fuel-injection systems of mixture-compressing internal combustion engines having externally supplied ignition.

摘要： A housing body of a fuel injector has a multi-part design; it includes a base member and at least one calibrating sleeve. Air is supplied and metered in through the calibrating sleeve, while the base member is used for sealing and attachment purposes. A dimensionally accurate machining of calibrating sleeves can be carried out simply and cost-effectively. The structural design easily yields many different variants. The fuel injector is especially suited for fuel-injection systems of mixture-compressing internal combustion engines having externally supplied ignition.

摘要： A stop plate for assembly between a stop shoulder of a valve needle and an inner shoulder of a valve casing in known fuel injection valves. The stop plate limits the stroke of the valve needle and, between its through opening and its circumference, has an assembly slot. During the flanging of the valve casing and the high axial forces connected with this assembly a high edge pressure at the assembly slot and nonuniform deformations of the valve casing may occur. The stop plate includes at least two recesses which are formed in an upper stop face of the stop plate, the said stop face resting against the inner shoulder of the valve casing, these recesses lying symmetrically to a center line of the assembly slot and in a half of the stop plate in which the assembly slot is not formed. The recesses lead to a uniform and reduced impressing of the stop plate into the valve casing. This configuration of the fuel injection valve is particularly suitable for fuel injection systems of spark-ignition internal combustion engines.

摘要： The protective cap for a fuel injection valve having a recess which extends radially outwards from a through flow passage, this recess being so small that it has a capillary effect on the fuel, so that when the internal combustion engine is stopped, the fuel constituents which boil at high temperatures are deposited on the radially outer edge of the recess, due the capillary action, and the injection orifice of the fuel injection valve remains free of deposits. The protective cap can be used for different types of fuel injection valves.

摘要： An installation device for installing a fuel injection valve in a receiving bore of a cylinder head of an internal combustion engine. The installation device has a sheath element which at least partially encloses the fuel injection valve. The installation device can be introduced, together with the fuel injection valve, into the receiving bore. An inwardly angled first collar section, which can be nonpositively joined to a receiving section of the fuel injection valve receiving the first collar section in order to transfer both a pressing force serving to press the fuel injection valve into the receiving bore and a pulling force in the opposite direction, is provided on a first end of the sheath element. An outwardly angled second collar section, which offers an application surface for a tool for applying both the pressing force and the pulling force, is shaped onto a second end of the sheath element located opposite to the first end.

摘要： The present invention relates to an injection valve, in particular to the injection valve for a direct injection of fuel into a combustion chamber of an internal combustion engine. The injection valve includes a valve body mounted in a housing, the valve body having a valve opening surrounded by a valve seat. A valve needle is provided with a closing head extending through the valve opening so that the closing head cooperates with the valve seat to snugly fit into valve seat on the injection discharge side. The valve needle is prestressed by a closing spring into a closing position and moved by an actuating mechanism through an actuating element against the force of the closing spring into an open position. To allow the injection valve to open quickly, the actuating element is closely engaged with the valve needle using a spring acting in the direction of the open position.
