摘要： In known electromagnetically operated valves, a valve tube as the principal element in the valve comprises three sections: a core and a valve seat support are connected to one another by a non-magnetic intermediate section so as to create an hydraulic seal, at least two joint and connection sites being required. In the novel valve, the number of components of the valve tube (12), and thus also the number of joints/connections, is reduced. The entire valve tube is made of magnetically conducting material, thus making it possible to dispense with non-magnetic intermediate parts. The valve is especially suitable for use in fuel injection systems in compression and spark ignition internal combustion engines.

摘要： The invention relates to a fuel injection valve for fuel injection systems of internal combustion engines in which there is an extended, axial, thin-walled, non-magnetic sleeve (12). At the downstream end said sleeve (12) has a base section (20) running substantially perpendicularly to the otherwise axial extent of the sleeve (12) along a longitudinal valve axis (10). A valve needle (28), firmly secured to an armature (24) and a valve closer (30), can move axially in a through aperture (21) in the sleeve (12). The valve closer (30) operates together with a valve seat (35) on a valve seat body (25), where the valve seat body (25) is pressed into the sleeve (12) and, for instance, thus bears on the base section (20) of the sleeve (12). The sleeve (12), in the form of a deep-drawn sheet-metal component, extends axially over more than half the axial length of the fuel injection valve. The fuel injection valve is particularly suitable for use in fuel injection systems of mixture-compressing spark-ignition internal combustion engines.
