Abstract: An electromagnetic actuator for an assembly, in particular in a motor vehicle, may be mounted on a fluid chamber, which is designed to be connected to the actuator for fluid transfer when the actuator is installed in the assembly, which has a moving armature in an armature chamber, where the armature has a moving armature rod, where the actuator is designed to fill the armature chamber with fluid, in particular oil, in that the armature rod moves such that fluid is drawn into the armature chamber from the fluid chamber through a fluid path when the armature rod is connected to the fluid chamber for fluid transfer, and where a flow resistance in the fluid path between the armature chamber and the fluid chamber can be set to a first resistance level or a second resistance level.

Abstract: An actuator for an assembly in a motor vehicle may have a moving armature in an armature chamber, where the actuator has a fluid path that is configured for fluid transfer between the armature chamber and a fluid reservoir in the assembly when the actuator is installed in an assembly, where the actuator is configured to fill the armature chamber with fluid, in particular oil, when the armature moves axially, thereby drawing fluid into the armature chamber when the actuator is operated in a fluid chamber, in particular an oil chamber.

Abstract: An electromagnetic actuator (1) for an assembly, which has a fluid space configured to be fluidically connected to the actuator when the actuator is installed in the assembly, includes a movable armature in an armature space (6). The armature includes a movable armature rod (8). The actuator is configured to fill the armature space (6) with fluid, such as oil, via axial movements of the armature rod that draw fluid from the fluid space into the armature space (6) through a fluid path when the armature rod is fluidically connected to the fluid space.

Abstract: A hydraulic system is described, in particular for a motor vehicle transmission, with an actuator, a valve, a pressure supply line and a tank line. The actuator may have a first pressure chamber and a second pressure chamber, which can have pressure applied for actuation of the actuator, wherein the pressure chambers, the pressure supply line and the tank line are each connected to a port (A, B, P, T) of the valve. The valve may have several different switching positions, in which the pressure chambers with the pressure supply line or the tank line are selectively connected to each other or shut off from each other.
