  • Patent number: 5016821
    Abstract: A fuel injection valve comprising a housing, a valve seat located in the housing, and a valve needle having a peg at an end thereof which peg defines with a downstream opening of a nozzle body located in the housing and forming the valve seat an annular space. A platelet is located between the nozzle body and a processing sleeve connected with the housing. The platelet has a plurality of bores extending from the annular space.

  • Patent number: 4934605
    Abstract: A fuel injection valve comprising a housing, a valve seat located in the housing, and a valve needle having a seated portion cooperating with the valve seat to define a fuel flow area and having a form of a rounding formed by a part of an outer circumference of an imaginary torus.

  • Patent number: 4903898
    Abstract: A fuel injection valve which is used to inject fuel into the intake tube of a mixture compressing internal combustion engine having externally supplied ignition. The fuel injection valve includes a nozzle body, in which a valve seat face is embodied. Cooperating with the valve seat face is a valve needle on which an armature that is electromagnetically actuated by a magnet coil is secured. The valve needle has a first guide section and a second guide section. A flat plate is disposed downstream of the valve seat face and four bores spaced apart from one another by equal intervals are provided in the flat plate.

  • Patent number: 4700891
    Abstract: A magnetic injection valve for injecting fuel into the intake tract of internal combustion machines, which is distinguished by particularly good internal cooling. A magnetic coil wound onto a coil carrier is located in the valve, being introduced into a valve housing and surrounds a ferromagnetic core. The core acts upon an armature which is connected to a movable valve needle. A bushing in the core and a sleeve located outside the core are arranged such that the fuel, emerging from an inflow tract of a supply device flows via the sleeve serving as a fuel line and reaches the interior of the valve housing that receives the magnetic coil; after flowing virtually completely around the magnetic coil, the fuel leaves this interior via a bore and flows back between the bushing and the core as far as the end of the bushing, and then flows on through the bushing to reach the armature to flow on to the valve seat.

  • Patent number: 4678124
    Abstract: An electromagnetically actuatable valve, in particular a fuel injection valve for fuel injection systems, which serves to supply fuel to internal combustion engines. The fuel injection valve comprises a valve chamber and a core upon which a magnet coil is wound by use of a carrier body. A flat armature is constructed in such a manner at its side facing core that it partially overlaps the front surface of a ferromagnetic valve chamber with its outer range of action so that the magnet circuit is guided to the flat armature via valve chamber and the front face and so that magnetic coil, when actuated, simultaneously serves as a detent for the flat armature.
