The invention relates to an electromagnetically controllable suction valve () for a high-pressure fuel pump (), comprising a magnet assembly () and a hydraulic module (), the hydraulic module () engaging at least in sections in an annular magnet coil () of the magnet assembly (). According to the invention, a heat-conducting material () and/or a heat-conducting body () is/are arranged between the magnet coil () and the hydraulic module (). The invention further relates to a method for producing an electromagnetically actuatable suction valve ().

Electromagnetically actuatable suction valve and method for producing an electromagnetically actuatable suction valve

The invention proposes an electromagnetically actuatable inlet valve () for a high-pressure pump, in particular of a fuel-injection system. The inlet valve () has a valve member () which can be moved between and open position and a closed position. An electromagnetic actuator () is provided, by means of which the valve member () can be moved, wherein the electromagnetic actuator () has an armature () which acts at least indirectly on the valve member (), a magnet coil () which surrounds the armature (), and a magnetic core () against which the armature () comes to rest at least indirectly when current is applied to the magnet coil (), wherein the armature () is movably guided in a carrier element (), and the carrier element () and the magnetic core () are interconnected. The carrier element () and the magnetic core () are interconnected by a sleeve-shaped connection element () which is integrally bonded in a first connection region () to the carrier element () and/or the magnetic core (), and interlockingly engages the carrier element and/or the magnetic core in a second connection region () offset relative to the first connection region () in the direction of the longitudinal axis () of the connection element ().

The invention relates to a fuel metering device for regulating the delivery rate of a high-pressure fuel pump of a fuel injection device for an internal combustion engine. The fuel metering device has a control valve actuated by an electromagnet and having a valve member. The electromagnet has an armature and an armature rod and the armature rod is axially movably supported in at least one bushing. The at least one bushing is designed as a solid, one-piece metal component. The bushing is preferably made of steel and the bearing surface thereof, in which the armature rod is supported, has a nitrocarburized and polished surface layer.
