£s ict bekannt, die zur steuerung einer brennkraftmaschine vorgesehenen Ventile hinsichtlich ihrer Hubhöhe und der Offnungs- und Schi ieot;r:e i ten regelbar zu gestalten. Das geschieht bei einer Ausführungsform durch zwischen dem Nocken und dem Ventilschaft angeordnete Doppelscnlepphebel, deren eine .unäen uuj c inander lie gen und deren andere in einen Schwenkhebel getrennt drehbar gelagert sind. Durch Seioegen des Jchwenkhcoels verschieben sicti die freien ~nden der Schlepphebel gegeneinander, wodurch infolge besonderer ausbildung der Berührungsflächen der ..üstand zwischen der arbeitsfläche aes ooeren Hebels und dem Ventilschaft zu- üsij* αΰηϊι.Ί,ι.ιζ.It is known to design the valves provided for controlling an internal combustion engine so that they can be regulated with regard to their lift height and the opening and closing positions. In one embodiment, this is done by means of double rocker arms arranged between the cam and the valve stem, one of which is located in one another and one of which others are rotatably mounted separately in a pivot lever. By separating the Jchwenkhcoels sicti shift the free ~ nd the rocker arm against each other, which as a result special formation of the contact surfaces of the ... between the working surface of the upper lever and the valve stem zu- üsij * αΰηϊι.Ί, ι.ιζ.
Lei einer ander en Ausführungsform einer regelbaren Steuerung sind j dr jedes Ventil zwei Noci-tcn und zwei ^tassel vorgesehen, axe ober, durch ein ^elenkstück miteinander in Verbindung stehen. Oaa ..bnehuen der ventilbev:egung erfolgt hier durch einen ν er schwenkbar en Zuiischenaebcl, der über d,emLei another embodiment of a controllable one Control are j dr each valve two noci-tcn and two ^ tassel provided, ax above, through a joint piece in Connected. Oaa ..bnehuen the valve movement takes place here by a ν er schwenkbar en Zuiischenaebcl, which over d, em

Die ..nordnung kann auch so getrofj en cein, decs die beiden für jedes Ventil bestimmten Nocken/Im 'einem durch Eandgriff υ er schwenkbar e\ Gegv.enz angeordnet sind, durch das sie wahlweise in ihre ^ eDro.uch.se te llung gefuhr τ werden·The ..order can also be trofj en cein, decs die two cams intended for each valve are arranged in a pivotable manner through which they τ can optionally be routed to your ^ eDro.uch.se te l
'lchliecslich ist es bei Jinspritzpumpen bekannt, Doppe!schwinghebel für die Brennstoff nadel vorzusehen, von denen der eine gegenüber dem anderen exzentrisch gelagert ist und die aufeinander einwirken.After all, it is known with injection pumps that Double rocker arm to be provided for the fuel needle from which one is eccentrically mounted in relation to the other and which act on one another.
Bei den Dekannten Ausführungsfor men erfolgt also die lege lung der steuerung entweder durch Einschalten eines grosoen Spieles zrjisehen kochen und Ventilsiössel, looäurch schlagartige Beanspruchungen wad ein sehr lauter Sang entstehen oder aber es ist ein er lieblicher „uf-xanä erforderlich, der eine ziemliche ..nfälligkeit ceg enu'oer Störungen auf we ist.So in the case of the decanned embodiments the setting of the control either by switching on a Great game of cooking and valve poppet, looäurch sudden stresses wad a very loud chant or a more lovely "uf-xanä" is required, which is quite a .. vulnerability to ceg enu'oer disturbances on we.
