Abstract: A system and method for regulating a flow of a fluid, wherein the system comprises a regulating device and a central axis, wherein the regulating device is adapted to establish at least one through-passage opening for the fluid, wherein a normal vector of a cross sectional area of the at least one through-passage opening is oriented parallel to the axis, wherein a size of the cross-sectional area is adjusted in dependence on the rotary speed of the regulating device turning about the central axis.

Abstract: A system and method for regulating a flow of a fluid, wherein the system comprises a regulating device and a central axis, wherein the regulating device is adapted to establish at least one through-passage opening for the fluid, wherein each time a through-passage opening is situated between two transport ducts for the fluid, wherein a normal vector of a cross sectional surface of the at least one through-passage opening is oriented parallel to the axis, wherein a size of the cross-sectional surface is adjusted in dependence on the rotary speed of the regulating device turning about the central axis.

Abstract: A coolant supply system for a drive device of an electrically operated vehicle axle with an electric machine which has a cylindrical stator housing, in which there is a winding head space axially on both sides of a rotor/stator arrangement, at the bottom of which coolant collects. The two winding head spaces are fluidly connected to one another via a coolant sump, and the stator housing height and the coolant sump height in the electric machine vertical direction add up to a total height. In order to reduce the total height, the coolant sump is offset by a transverse offset from a rotor axis vertical plane. In this way, the stator housing height and the coolant sump height can at least partially overlap in the vertical direction of the electric machine by an overlap amount.

Abstract: A coolant supply system for a drive device of an electrically operated vehicle axle of a two-track vehicle with an electric machine. The coolant supply system has an electric machine hydraulic circuit in which a coolant tank, the interior of a cylindrical stator housing and a stator housing sump are integrated, in which the coolant draining from the stator housing collects, which can be returned from there to the coolant tank by at least one return pump. The stator housing sump has a suction point on each of its axially opposite axial sides, from which the coolant can be sucked off by the return pump.
