Abstract
An electromechanically actuatable pressure medium control valve. The control valve includes a valve housing, an armature, a pole core, a valve casing with a control cross-section, and a closing element controlling a pressure medium flow through the control cross-section. The pressure medium control valve allows for a different throttling of a pressure medium flow between a first valve opening and a second valve opening according to the flow direction of the pressure medium flow through the pressure medium valve.
Claims11
An electromechanically actuatable bi-directional pressure medium control valve, comprising:
- a valve housing in which an armature that can be driven to perform a stroke movement in a direction of a longitudinal valve axis is movably accommodated;
- a pole core configured to limit the armature movement in one direction of movement;
- a valve casing with a control cross-section formed thereon;
- and
- a closing element which controls a pressure medium flow through the control cross-section and can be actuated by the armature, wherein the closing element is coupled to the armature by a tether device, wherein the tether device includes an armature capsule which is fixed to the armature and in which the closing element is displaceably accommodated,
- wherein the closing element and the control cross-section are configured for different throttling of a pressure medium flow between a first valve opening and a second valve opening according to a flow direction of a pressure medium flow through the electromechanically actuatable bi-directional pressure medium control valve, such that the pressure medium flow is throttled when the pressure medium flow is in a first flow direction from the first valve opening to the second valve opening and the pressure medium flow is throttled differently when the pressure medium flow is in a second flow direction from the second valve opening to the first valve opening.
