Summary:The element i.e. oil control valve (1), has a connecting region (2) accommodated within a hollow rotatable component i.e. hollow cam shaft (3), and a through-hole opening (18) axially formed in the connecting region. An entry zone (4) is attached to the connecting region, and flows in a control section (6), and a calibrating element i.e. pivot, is attached to the through-hole opening, and includes central or eccentric calibrating opening. The calibrating element is arranged within the element and the rotatable component, and the entry zone is provided with a filter element (17). Die Erfindung betrifft ein Mediumsteuerelement (1), das mit seinem Verbindungsbereich (2) innerhalb eines drehbaren Bauteils (3) aufgenommen ist. Um das Mediumsteuerelement (1) und Lagerstellen des drehbaren Bauteils (3) über eine einzige Mediumversorgungsleitung mit Medium versorgen zu können, ist vorgesehen, dass in dem Verbindungsbereich (2) eine Durchgangsöffnung (18) eingebracht ist.
