An apparatus for handling fluid within an at least partially electrically driven vehicle, with a valve device including a valve housing. The valve housing includes at least three two radially arranged port openings and at least one axially arranged port opening for the inflow and/or outflow of fluid, and a valve body which is arranged inside the valve housing and is configured to be rotatable about an axial axis of rotation R. The valve body includes a first connecting channel of arcuate shape for connecting two radially arranged port openings and a second connecting channel of arcuate shape for connecting a radially arranged port opening with an axially arranged port opening. The at least two radially arranged port openings define a base plane B, which is configured orthogonally to the axial axis of rotation R, and the first arcuate connecting channel defines a first connecting channel plane V.

Apparatus for handling fluid within an at least partially electrically driven vehicle

An actuator for a hydraulic stroke or pressure control valve for a motor vehicle, the actuator including a magnetisable actuator housing that envelops a magnet coil; a pole group arranged in a receiving opening of the actuator housing, wherein the pole group includes a pole core and a pole tube, wherein an axially movable armature is arranged in an inner cavity of the pole group, wherein the armature is configured to axially move a piston of the hydraulic valve by a pin that is supported axially movable in the pole group, wherein the actuator is configured to perform an anti-stick function and a contact damping function, wherein the pin directly contacts a first armature face of the armature that is oriented towards the pin, and wherein the pin is configured axially movable relative to the armature.

Actuators for hydraulic valve

A hydraulic valve including a valve housing including a longitudinal axis, a receiving opening extending along the longitudinal axis, a first flow through opening of a supply connection, a second flow through opening of an operating connection, a third flow through opening of a tank connection, wherein the first flow through opening, the second flow through opening and the third flow through opening are configured at least partially flowable by a hydraulic fluid flowing through the valve housing, and a valve piston with a control groove which valve piston is axially displaceable in the valve housing in the receiving opening along the longitudinal axis, wherein the flow forces of the hydraulic fluid imparted upon the valve piston are oriented away from a first switching position of the hydraulic valve where the hydraulic fluid flows from the first flow through opening into the second flow through opening.
