Abstract: A method for producing a filter element includes forming longitudinal ducts extending between upstream and downstream surfaces of the filter element, and installing a heating element for heating regions of walls of the ducts along longitudinal extent of the walls. The filter element is arranged inside an injection valve of an internal combustion engine.

Abstract: A method for heating a fuel flowing through an injection valve into a combustion space of an internal combustion engine includes conveying fuel through ducts of a filter element arranged in the fuel flow, heating walls of the throughflow ducts at least in certain regions along their longitudinal extent, and introducing heat from the walls into the fuel.

Abstract: A pressure sensor includes a housing, an interior chamber of which is sealed by a diaphragm, and a flexible measuring element, which is positioned separately. In addition, the pressure sensor includes a transmission element, which is formed as a chip and is used to transmit force from the diaphragm to the measuring element. In response to a selected deformation of the measuring element, a stop element comes into contact with a region of the transmission element and opposes the applied force. Therefore, it forms an overload protection. The stop element may be configured as a bending bar and/or form a second measuring element, the first measuring element being configured to measure relatively low pressures, and the second measuring element or stop element being configured to measure relatively high pressures. The pressure sensor thus provides a plurality of measuring ranges.

Abstract: An injection valve for internal combustion engines has a filter element arranged on the inside of the injection valve in the fuel flow of the latter with ducts for the fuel. The filter element is designed as a throughflow heating element, for which purposes the walls of the throughflow ducts are capable of being heated, at least in certain regions, along their longitudinal extent.

Abstract: A flushable bi-fuel injector, in particular for combustion engines, comprises a nozzle body incorporating a nozzle exit (11), a movably held valve needle (12) for opening and closing the nozzle exit (11), a first supply channel (13) for supplying a first liquid or a first fuel to the nozzle exit (11); and a second supply channel (23) for supplying a second liquid or a second fuel or a liquid additive to the nozzle exit (11). A ring-shaped slide gate (21) or a ring piston is arranged in a ring-shaped chamber (20) within the nozzle body (1). The slide gate (21) can be hydraulically activated to either side via differential pressure. Depending on its position, the slide gate (21) connects either the first supply channel (13) or the second supply channel (23) to the nozzle exit (11).
