    Zwangläufge Vontlleteuerung.   



   Gegenstand der   Erfindung   ist eine   zwan'äufige Ventilsteuerung,   die in Fig. 1 im Vertikalschnitt nach   c-d,   in Fig. 2 im Horizontalschnitt nach a b dargestellt ist. Sie besteht aus einer Schwingscheibe e mit Kurvenstück g, das von der   Exzenterstange I beim Anhube nach   der Ventilspindel   1, zu bewegt   wird, einer Rolle i, die beim Herannahen der Kurve   g   ausweicht, und aus einem um einen Fixpunkt k drehbaren Lenker 1, welcher die Rolle trägt und den Führungszylinder   tU   vermittels Führungsbacken n mitnimmt. 



   Die   Ventilspindel   wird bei dieser Konstruktion frei von allen   Seitendrücken   gehalten, da der Lenker   1   bezw. dessen   : fixer Drehpunkt   alle Seitendrücke auffängt, und ferner werden selbst bei kleinen Füllungen sehr wirksame Ventilhübe erzielt, da die Bewegungsrichtung der Kurvenscheibe e mit derjenigen der Rolle t im Rollenmittelpunkt beim Momente des Anhubes einen stumpfen Winkel x einschliesst, wodurch sich wesentlich grössere Ventilhube als bei der umgekehrten Bewegungsrichtung erzielen lassen, wie mathematisch nachgewiesen werden kann. 



  Die Exzenterstange ist bei der Verwendung der Steuerung für Einlass auf Druck beansprucht, während bei Auslass Zugbeanspruchung vorliegen würde. Die Schlussbewegung des Ventils erfolgt in bekannter Weise unter Einwirkung einer Ventilfeder o.

    Inevitable volume control.



   The subject of the invention is a two-stage valve control which is shown in Fig. 1 in vertical section according to c-d, in Fig. 2 in horizontal section according to a b. It consists of an oscillating disk e with curve piece g, which is moved by the eccentric rod I when it is lifted towards the valve spindle 1, a roller i which evades as the curve g approaches, and a link 1 which can be rotated about a fixed point k and carries the role and takes the guide cylinder tU by means of guide jaws n.



   The valve spindle is kept free of all side pressures in this construction, since the handlebars 1 respectively. whose: fixed pivot point absorbs all side pressures, and furthermore, very effective valve lifts are achieved even with small fillings, since the direction of movement of the cam disc e with that of the roller t in the center of the roller encloses an obtuse angle x at the moment of the lift, which results in a much larger valve lift than at the opposite direction of movement can be achieved, as can be proven mathematically.



  When using the control for inlet, the eccentric rod is subjected to compression, while at the outlet there would be tensile stress. The final movement of the valve takes place in a known manner under the action of a valve spring or the like.
