    摘要: A fuel injection valve for internal combustion engines, with a high pressure connection, which feeds laterally into a valve retaining body inserted into the engine housing, which connection is constituted by a pressure pipe connector which is inserted into a through bore in the housing. The pressure pipe connector is connected to a pressure line by means of a male pipe fitting and is axially braced by this fitting against a seat on the circumference face of the valve retaining body. In order to limit the clamping forces of the high pressure connection introduced radially onto the valve retaining body, a region is provided between the force introduction onto the pressure pipe connector and its contact with the valve retaining body, which region plastically deforms from a particular clamping force onward.

    摘要: A fuel injection valve for internal combustion engines having, a valve member, which is axially displaceable in a valve body and which on one end has a valve sealing face with which it cooperates with a stationary valve seat in order to control an injection cross section, and having at least one valve spring, which urges the valve member in the direction of the valve seat and is braced on its other end on a stationary stop. To increase the spring force of the valve spring while the outer diameter remains the same, the windings of the valve spring, embodied as a helical spring, have a circular basic cross section (Y), which in a region pointing radially outward from the axis (X) of the valve spring has a ground face oriented parallel to the spring axis (X).

    摘要: A fuel injection valve for internal combustion engines that has a valve member which is guided axially displaceably in a guide bore of a valve body and which on an end toward the combustion chamber has a valve sealing face that cooperates with a valve seat face, formed on an end of the guide bore toward the combustion chamber, for controlling the communication between a high-pressure conduit in the valve body and at least one injection opening A diversion conduit in the valve member, by way of which diversion conduit the high-pressure conduit can be made to communicate with a relief chamber when the valve member has lifted from the valve seat face. Once the maximum opening stroke of the position of the valve member is reached, the diversion conduit is closed by a sealing face provided on the valve member, so that the entire supplied fuel quantity can attain injection.
