    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: A fuel/air mixture device for a dual injection valve including a single-part element which is suitable for various fuel injection valves without further adjustment measures. The single part element includes an envelope bush portion in contact with the injection end of the fuel injection valve in the form of stop surfaces and, together with this injection end, forms a narrow air gap so that the air is accelerated to almost sonic velocity and the fuel sprayed from the fuel injection openings is finely atomized. The device is particularly suitable for injecting a fuel air mixture into the induction pipe of an internal combustion engine with externally induced ignition.

    摘要: A device for injecting a fuel-gas mixture having a cup-shaped gas enveloping sleeve in which the cylindrical part of the gas enveloping sleeve permits exact centering of the gas enveloping sleeve relative to the fuel injection valve. The novel device while having very exact centering of the gas enveloping sleeve relative to the fuel injection valve has the advantage of a simple, economical manufacture. The device includes radially inwardly pointing guide strips that rest with their face ends on the circumference of the fuel injection valve and thus in a simple way center the gas enveloping sleeve relative to the fuel injection valve. The device for injecting a fuel-gas mixture is especially well-suited for injection of a fuel gas mixture into the intake tube of a mixture-compressing internal combustion engine with externally supplied ignition.

    摘要: An electromagnetically actuatable valve intended in particular for the injection of fuel into the intake manifold of mixture-compressing internal combustion engines with externally supplied ignition. The valve includes a flat armature which is firmly connected with a movable valve element, embodied as a ball, to cooperate with a fixed valve seat. The flat armature is supported on a first side so as to pivot about a tilt edge provided on said side and remote from the valve seat and is retained at the tilt edge on this side by the force of a spring engaging the first side of the flat armature oriented toward the valve seat. The unilateral retention of the flat armature at the tilt edge assures the unequivocal upward and downward movement of the flat armature.

    摘要: An electromagnetic fuel injection valve in which a valve needle coupled to the armature has twisting channels for carrying fuel and for creating turbulence therein. The channels terminate in a pressure chamber whose volume is chosen to be equal to or smaller than the volume of fuel injected in a single stroke.
