Abstract (en)
The thrust rod (1) with a ball-shaped end bearing component (13) is hydraulically located in a cup (7) accommodating the swing lever (2). The cup has a feed channel (16) for hydraulic oil connected to the engine lubricating oil circuit. The bearing component consists of a ball which is supported in a ball bowl, which runs out into a cylindrical bore (26). Alternatively the bearing component may be a piston which is held in a cylindrical bore of the swing lever. The feed channel issues in the centre of the ball bowl and consists of a bore with relatively small dia. It has a check valve (17) which comprises a small ball (18) in the channel which it opens or closes dependent upon the position of the swing lever on a cam of the camshaft.

Bei einer Vorrichtung zum Ventilspielausgleich von Ein- und Auslaßventilen einer Brennkraftmaschine ist zwischen einem Kipphebel und einem Schwinghebel eines Ventiltriebs eine Stoßstange (1) über eine hydraulische Lagerung im Schwinghebel (2) gehalten. Die hydraulische Lagerung besteht aus einer Kugelpfanne (15) in der das eine eine Kugel (13) aufweisende Ende der Stoßstange (1) gelagert ist. Die Kugelpfanne (15) weist zur Zuführung von Hydrauliköl einen Zuführkanal (16) auf, der mit dem Schmierölkreislauf des Motors verbunden ist. Der Zuführkanal (16) kann mit einem Rückschlagventil (17) versehen sein. <IMAGE>
