Abstract: Various embodiments include a high-pressure port for a fuel pump comprising: a body defining an internal volume; an outlet valve with an element opening in a first direction; a pressure-limiting valve with an element opening in an opposite second direction; a common valve plate including a sealing seat for both valve elements; and a sleeve guiding the outlet valve element during movement, fastened in the body with an axial stop limiting movement of the outlet valve element and a radial guide guiding the outlet valve element during movement. The guiding sleeve comprises a harder material than the body.

Abstract: An electromagnetic actuator includes an armature which has a stop face, and a pole piece which has a counter stop face, wherein the stop face and the counter stop face in terms of geometry are configured so as to be mutually complementary such that the stop face and the counter stop face in a movement of the armature toward the pole piece engage in one another, displacing a medium which is disposed between the stop face and the counter stop face. An electromagnetic valve may include the electromagnetic actuator, and a high-pressure fuel pump may include the electromagnetic valve.

Abstract: A bearing assembly includes a bearing housing which can be fixed directly to a foundation, guide elements which support a rotating shaft, and damping elements which support the guide elements against the housing. The damping elements are preferably located outside the housing, where they are supported by support elements passing through the housing and retained by covers attached to the housing.

Abstract: A drive system includes a drive shaft with first and second shaft sections connected by a diaphragm clutch having a diaphragm assembly. The radially outer end of the diaphragm assembly is connected to a disk having a first toothing arranged on one face of the disk. The first toothing engages in corresponding second toothing on a flange connected to the first shaft section when the diaphragm assembly is subjected to an axial preload. A contact-pressure device that is controllable by remote control in the stationary condition acts against the disk to produce the preload.
