Abstract: A lower filter for a fuel injector includes a disk having an annular shape and including a plurality of filter holes. The disk is positioned upstream of a valve guide of an internal valve assembly without contacting the valve guide. The disk prevents internally generated contaminants contained in fuel flowing through the filter holes from reaching a valve guide area and a sealing area of the internal valve assembly. By installing the lower filter upstream of the valve guide and without contact to the valve guide, interference with the guidance and reciprocal movement of the valve is avoided. Application of the lower filter in fuel injectors may reduce the occurrence of injector failures by reducing the number of stuck open conditions in injectors and by reducing the number of hydro lock engine incidents without interference with the valve guide.

Abstract: The invention relates to a fuel-injection valve for internal combustion engines. Said valve comprises a valve body (1), in which a plunger-type valve needle (5) is positioned in a bore (3) so that it can be displaced longitudinally. The valve needle (5) has a valve sealing surface (7) comprising at least one conical surface (30; 32). The valve seat surface (7) of said valve needle (5) co-operates with a conical valve seat (9) that is configured in the valve body (1), in such a way that when the valve needle (5) is lifted from the valve seat (9), fuel streams from a pressure chamber (19) between the conical surface (7) and the valve seat (9) through at least one injection orifice (11). Several depressions (40), whose respective depths are different in at least two places, are configured around the periphery of the conical surface (7) and/or the valve seat (9).

Abstract: A fuel direct injection valve for diesel engines, in which a needle valve is rotated by first and second serrations formed in an edge portion of an opening of a nozzle body and in a base portion of the needle valve and by third and fourth serrations formed on the axially opposite side to the first and second serrations, and in which as the needle valve rotates, the area of the portion where a first nozzle hole formed in the nozzle body overlaps with second nozzle hole formed in a rotary valve increases. In the low load operation region, the area is small. In the high load operation, the area increases with the fuel injection pressure, so that the complete penetration force of the fuel injection can be large and constant, and the fuel effectively contacts and strikes squished air and satisfactory mixes with the air. This minimizes the delay of ignition and enhances the combustion, low-noise, and exhaust emission performances.

Abstract: A fuel injector for an internal combustion engine, including a housing, a homogeneous member defining a continuous wall having a seat portion and a guide portion, a closure member, and a metering disk. The housing includes an inlet and an outlet disposed along a longitudinal axis. The homogeneous member is disposed proximate the outlet. The seat portion includes a sealing surface and a seat orifice. The closure member is disposed in the housing and positioned by the guide portion for reciprocal motion along the longitudinal axis between a first position such that the closure member is displaced from the seat, allowing fuel flow past the closure member, and a second position such that the closure member is contiguous the seat, precluding fuel flow past the closure member. The metering disk is proximate the seat orifice.

Abstract: The invention relates to an injection valve comprising a housing, a retaining nut and a nozzle body, said retaining nut prestressing the nozzle body against the housing. The surface mating between the retaining nut and the nozzle body is optimized in such a way that an intense prestressing force is exerted on the nozzle body without damaging the retaining nut. At the same time, the prestressing force optimizes the support of the pressure chamber in such a way that a nozzle body which is resistant to high-pressure is provided.
