   Die Teile   h, h2 und k können,   wie in dem Ausführungsbeispiel dargestellt, von einem geschlossenen Gehäuse p umgeben sein, welches ständig mit Öl gefüllt gehalten werden kann. Das öl teilt sich den Ventilspindeln, die labyrinthdichtungsartig ausgestattet sind, und ihren Führungsbüchsen mit, so dass eine sehr zuverlässige Schmierung erzielt wird. 



   Der erläuterte Antrieb für die Ventile kann natürlich für   Ventilkonstruktionen   beliebiger Art, insbesondere auch für entlastete Ventile Anwendung finden und ebenso ist die Antriebsvorrichtung nicht nur auf Einlassventile beschränkt, sondern kann auch zur Steuerung der Auslassventile Anwendung finden. 



   Bei dem in Fig. 3 dargestellten   Ausführungsbeispiel   sind die Ventile C mit teilweiser Entlastung konstruiert. Die Ventile schliessen an zwei Dichtungsflächen D und   D   ab, die derart verschiedene Durchmesser haben, dass zu der Belastung durch die Schliessfeder f noch eine gewisse Belastung durch das   Betriebsmittel   hinzutritt. Wie vorher schon erwähnt. können die Ventile jedoch auch so ausgebildet werden, dass sie völlig entlastet sind. 



   Der Rollenschubmechanismus ist bei Fig. 3 gegenüber der   ersten Ausführungsform   in der Weise umgekehrt, dass der Teil H Rollen trägt, auf welche der Hebel K. der zu einem entsprechenden   Kurvenstück ausgestaltet   ist, so einwirkt, dass die gewünschte Ventilbewegung erreicht wird.

   The parts h, h2 and k can, as shown in the embodiment, be surrounded by a closed housing p, which can be kept filled with oil at all times. The oil is shared with the valve spindles, which are equipped like a labyrinth seal, and their guide bushes, so that very reliable lubrication is achieved.



   The explained drive for the valves can of course be used for valve constructions of any type, in particular also for relieved valves, and the drive device is also not only limited to inlet valves, but can also be used to control the outlet valves.



   In the embodiment shown in FIG. 3, the valves C are designed with partial relief. The valves terminate at two sealing surfaces D and D, which have different diameters in such a way that, in addition to the load from the closing spring f, a certain load from the operating medium is added. As mentioned before. however, the valves can also be designed so that they are completely relieved.



   The roller push mechanism is reversed in Fig. 3 compared to the first embodiment in such a way that the part H carries rollers on which the lever K., which is designed as a corresponding cam piece, acts so that the desired valve movement is achieved.
