摘要： A dual component injector, especially for internal combustion engines, has a nozzle body, which has a nozzle outlet, and a valve needle for opening and closing the nozzle outlet. A first feed channel is used for supplying a first fluid to the nozzle outlet, and a second feed channel is used for supplying a second fluid to the nozzle outlet. Optionally, a fluid chamber, which is located in the nozzle body, is connected to the nozzle outlet. The second feed channel is connected to the fluid chamber or to the first feed channel via at least two bored holes. The bored holes open out in the fluid chamber or in the first feed channel in such a way that the second fluid produces a swirling flow pattern in the fluid chamber or in the first feed channel.

摘要： A fuel injector for the direct injection of fuel into the combustion chamber of an internal combustion engine includes a valve needle situated in a nozzle body, in which the valve needle is actuable by an actuator and acted upon by a restoring spring in such a manner that a valve closure member, which is in operative connection to the valve needle and faces the combustion chamber, is kept in sealing contact on a valve seat surface in the non-actuated state of the actuator. The valve needle is hollow at least in a downstream partial region and is sealed off from the combustion chamber at the front-side.

摘要： A compensating element for mounting and supporting a fuel injector in a cylinder head of an internal combustion engine is designed in the form of a washer and positioned between a valve housing of the fuel injector and a wall of a receiving bore of the cylinder head. The washer has a round or oval cross-section and sets apart a shoulder of the valve housing from a shoulder of the cylinder head.

摘要： A fuel injection valve, which may be inserted into a locator bore of a cylinder head of an internal combustion engine, has a sealing ring located peripherally around the fuel injection valve in the locator bore. The sealing ring has a contact surface, having the shape of a spherical segment, toward the fuel injection valve, which presses against a corresponding counter surface, having the shape of a spherical segment, of the fuel injection valve.

摘要： A fuel injection valve has a metal base body extending over its entire axial length, which includes a core/internal pole and a valve jacket. The internal pole is produced by extrusion and includes a valve inlet connection, the actual core of the electromagnetic circuit, a magnetic choke point and an area for guiding an armature. However, the valve jacket is produced by deep drawing. In addition to its function as a housing part, the valve jacket also serves as a valve seat carrier. A clearance is formed between the valve jacket and the internal pole, holding a magnet coil which is sealed by a ring gasket and is therefore dry. This fuel injection valve is suitable in particular for use in fuel injection systems of internal combustion engines with spark ignition and gas mixture compression.

摘要： In a fuel injection valve, after a preliminary adjustment of the valve seat support and immobilization thereof on the valve housing by way of a flanged rim, the effective stroke of the valve needle is measured, with the magnet coil energized, using an electrical displacement measurement system, and compared in the electronic control device to the reference stroke. In the event of a difference between these two values, the electronic control device activates a welding device which generates in an adjusting segment a first circumferential weld bead whose shrinkage upon cooling results in a decrease in the effective stroke. If, in a new measurement and adjustment cycle, the effective stroke still differs from the reference stroke, further weld beads are generated. The fuel injection valve is suitable particularly for the injection of fuel directly into the combustion chambers of internal combustion engines.
