Abstract

A further development of the patent application P3447321.1. In this application the sealing element is only under spring tension. It may happen, due to the centrifugal force, that the sealing element lifts off from the cylinder barrel. The roller tappet shell is now bedded in a recess with rotatable bearing of the sealing element, which slides on the cylinder wall. The sealing element is composed of ceramic (aluminium titanate + aluminium oxide fibres). A cam, the opposite end of which slides on the control cam and thus holds the sealing element on the slideway, engages in the tappet. Due to the centre of rotation of the sealing element in its recess very close to the slideway, wear is reduced. Lubricating oil is supplied to the sealing elements due to the periodic movement of the plugs. The latter have small oil pockets. At the outer dead-centre position the oil pockets are discharged up to the seal surfaces and the cylinder barrel. The circumferential surface of the piston (diesel engine) is lined with ceramic providing good insulation. Due to these measures the combustion temperatures are increased, thereby resulting in increased power and reduced fuel consumption and a reduction of the amount of pollutant emissions in the exhaust gases.

Dieses Steuergetriebe verleiht dem Dichtungs= körper eine genaue, nicht abhebbare Führung gegenüber der Zylinderwandung 6.The sealing body 2 consists of ceramic (aluminum = titanate + aluminum oxide fiber), which means that the sealing bodies are extremely wear-resistant. In part la of the stopper = sels 1 engages a cam lever 3, the part 3a aia control member 4a slides and which can be readjusted with a bolt-shaped guide 16 even in the engine piston is stored. This control gear gives the seal body a precise, Guide that cannot be lifted off from the cylinder wall 6.

Das Steuerorgan 42 sitzt auf der Motorwelle 4.The control element 42 is seated on the motor shaft 4.

Mit dieser Ausbildung ist ein zwangsläufiger Umlauf des Dichtungskörpers 2 entlang der Wandung 6 des Gehäuses gegeben.With this training there is an inevitable circulation of the sealing body 2 given along the wall 6 of the housing.

Durch den der Bahn 6 sehr nahe liegenden Schwenkmittel= punKt des Dichtungskörpers 2 in der Mulde lb, ergibt sich ein günstiges Führungsverhältnis, das die Abnutzung verringert.Due to the pivoting means, which is very close to the track 6, = point des Sealing body 2 in the recess lb, results in a favorable guide ratio, which reduces the wear and tear.

Die Schmieröl versorgung der Dichtelemente erfolgt mit Hilfe der periodischen Bewegung der Stöpsel (Dosier= pumpen ähnlich). Die Stöpsel besitzen im zylindristhen Teil la seitlich kleine Öltaschen 14, welche den dünnen Kanälen 15 des Motorkolbens gegenüber liegen. In der inneren Totpunktlage des Stöpsel la gibt ein Kolbenring 13 die Öleinlaufbohrungen 15 frei und diese füllen die Taschen 14 iit 01. In der äußeren Totpunktlage entleeren sich die Öltaschen in die Raume 11, Aussparungsbohrung lc und durch die kleinen Bohrungen 10 bis zu den Verteiler-Aussparungs-Bohrungen 2a. Von hier aus verteilt sich das Öl auf die naheliegende Dichtfläche 7 und die Laufbahn.The lubricating oil is supplied to the sealing elements with the help of the periodic Movement of the stopper (dosing = similar to pumping). The stoppers are cylindrically shaped Part la laterally small oil pockets 14, which the thin channels 15 of the engine piston lie opposite.
