A valve including a magnet actuator () which has a magnet coil (), a magnet armature () that moves in a stroke-like manner, and a pole core (), wherein the magnet armature () and the pole core () together limit a working air gap (), and the magnet armature () can at least indirectly contact the pole core (), wherein the valve also has a valve element () which can be moved between an open position and a closed position, and which is at least indirectly in mechanical contact with the magnet armature (). A separate magnet armature insert () arranged in the magnet armature () and/or a separate pole core insert () arranged in the pole core () is provided in the contact area of the magnet armature () on the pole core (), in order to achieve a separation of the mechanical and magnetic forces.

Valve, in particular a suction valve, in a high-pressure pump of a fuel injection system

The invention relates to a high-pressure pump (), in particular for a motor vehicle, for conveying a fluid, in particular fuel, e.g. diesel fuel, comprising a drive shaft having at least one cam, at least one piston, at least one cylinder () for mounting the at least one cam, wherein the at least one piston is supported on the drive shaft by the at least one cam, so that a translational motion can be carried out by the at least one cam as a result of a rotary motion of the drive shaft, at least one cover cap (), which is attached indirectly or directly to the outside of the cylinder (), wherein one end () of the at least one cover cap () rests on a projection () of the remaining high-pressure pump () for the interlocking attachment of the end () of the cover cap () to the projection ().

High-pressure pump

The invention relates to a high-pressure fuel pump (), in particular of a common rail injection system of an internal combustion engine, having a pump cylinder head (), having an intake valve () arranged in the pump cylinder head () in the direction of a pump cylinder axis, and a high-pressure fuel outlet () arranged laterally on the pump cylinder head (), wherein a protective cap (,) at least partly covering the high-pressure fuel pump () is provided. According to the invention, a high-pressure fuel pump () having a protective cap () is provided, in which the protective cap () can be mounted without difficulty on an assembled high-pressure fuel pump (). This is achieved in that a plug () having a lateral lead connection () is placed on the electrically operated intake valve (), and the protective cap () is formed in two pieces and has two protective cap parts (,) that can be fitted to each other, or else in that a plug () having a lateral lead connection () is placed on the electrically operated intake valve (), and the protective cap () is formed annularly and has a free clearance slot () interrupting the ring.
