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: Some embodiments may include a valve for a pump comprising: a first stop element having a longitudinal axis and a sealing seat; an actuator providing an actuator force along the longitudinal axis; a pin movable relative to the first stop element along the longitudinal axis and movable by the actuator force; a sealing element moved by the pin relative to the valve seat in order to open or close the valve; and a second stop element rigidly fastened to the first stop element providing a stop for the sealing element to limit movement of the sealing element away from the sealing seat along the longitudinal axis. The second stop element is fastened at a defined predetermined distance from the first stop element to define a spacing between the sealing seat and the stop.

Abstract: The invention relates to an electromagnetic switching valve for a fuel-injection system of an internal-combustion engine, which has an actuator region, for moving a closing element, with a pole piece and with an armature and also with a solenoid for generating a magnetic flux in the armature and the pole piece, said armature having a region of magnetic-flux concentration.

Abstract: Example embodiments relate to an electromagnetic actuator having an anchor which has a stop face, and having 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 anchor toward the pole piece engage in one another, displacing a medium which is disposed between the stop face and the counter stop face. The embodiments furthermore relate to an electromagnetic valve which has the electromagnetic actuator, and to a high-pressure fuel pump which has the electromagnetic valve.

Abstract: The present disclosure relates to a device for a high-pressure pump for a motor vehicle comprising a valve housing and an actuator assembly arranged substantially along the central axis of the valve housing. The actuator assembly may include a recess extending from a first end. The actuator assembly may include at least one hydraulic compensation opening extending through a wall of the actuator assembly from the recess into an exterior region.

Abstract: A valve arrangement for a high pressure pump includes a pump housing with a depression, and a valve housing configured to be inserted in the depression, and a clamping disc. The valve housing has at least one radial projection with a first axial boundary surface and a second axial boundary surface arranged opposite the first axial boundary surface, wherein the clamping disc extends radially over the radial projection of the valve housing and has a third axial boundary surface that corresponds with the second axial boundary surface of the valve housing. On the circumferential side, the clamping disc has a thread that can be screwed into a thread on the inner side of the depression to brace the valve housing onto the first boundary surface.

Abstract: A solenoid valve includes a housing, a valve actuation device, and a closing element, wherein the housing includes an interior space with a central axis, wherein the valve actuation device includes an actuator arranged in the interior space so as to be displaceable along the central axis, wherein the actuator is operatively connected to the closing element such that the solenoid valve is opened or closed by a displacement of the actuator along the central axis, wherein the actuator together with the housing delimit, in the interior space of the housing, a leakage chamber that can be filled with a fluid, e.g., a fuel, and wherein in the leakage chamber, at least one vortex generator is arranged on the housing and/or on the actuator, which vortex generator is configured to generate a fluid vortex in the leakage chamber.
