Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei Verbrennungsmaschinen mit hoher Verdichtung müssen die Kolbenlängen bei der Montierung bestimmt werden, wonach dann nachträglich der Kolbenkörper auf das erforderliche Maß abgedreht wird, um den genau vorgeschriebenen Kompressionsraum zu- erreichen. Mit Rücksicht auf die nicht immer genauen Aussparungen in den Verbrennungsräumen müssen bei ein und demselben Maschinenmodell die Kolben verschieden lang sein, um den richtigen Kompressionsraum und den richtigen Kompressions-Enddruck zu bekommen. Damit ist aber der Nachteil verbunden, daß die Kolben alle verschieden sind, was für die Fabrikation eine bedeutende Erschwerung" bedingt, insbesondere, wenn damit gerechnet werden muß, daß Ersatzkolben nachgeliefert werden sollen. Dieser Mißstand wird durch vorliegende Neuerung beseitigt, und zwar dadurch, daß zwischen den ohnehin aus zwei Teilen α und b bestehenden Kolben ein auswechselbarer Zwischenkörper, beispielsweise ein Ring c, von der erforderlichen Stärke (Dicke) eingeschaltet, d. h. bei der Montierung eingelegt wird. Je stärker der Ring c ist, desto kleiner wird der Kompressionsraum und umgekehrt. In the case of internal combustion engines with high compression, the piston lengths must be determined during assembly, after which the piston body is subsequently turned down to the required dimension in order to achieve the precisely prescribed compression space. In view of the not always precise recesses in the combustion chambers, the pistons of one and the same machine model must be of different lengths in order to obtain the correct compression chamber and the correct final compression pressure. This has the disadvantage, however, that the pistons are all different, which makes manufacturing a considerable problem, especially if it is to be expected that replacement pistons will be delivered. that between the piston, which already consists of two parts α and b , an exchangeable intermediate body, for example a ring c, of the required thickness (thickness) is switched on, ie inserted during assembly. The stronger the ring c, the smaller the compression space and vice versa.

Es können auf diese Weise sowohl der Kolbenteil b als der Kolbenteil α vollständig fertig im Vorrat hergestellt werden, und es genügt zur richtigen Bemessung des Kompressionsraumes, lediglich den Ring c nach der vorgeschriebenen. Stärke zu wählen. Es wird so ermöglicht, daß die beiden Kolbenteile in einer Größe in beliebig großer Anzahl hergestellt und für jedes Modell durch Zwischenlegen der -entsprechend starken Einlage c passend gemacht werden können.In this way, both the piston part b and the piston part α can be completely finished in stock, and all that is required for correct dimensioning of the compression space is the ring c according to the prescribed one. To choose strength. It is thus made possible that the two piston parts can be produced in one size in any large number and made suitable for each model by interposing the correspondingly strong insert c .

Claims (1)

Patent-Anspruch:Patent claim: Zweiteiliger Kolben für Verbrennungskraftmaschinen, dadurch gekennzeichnet, daß zwischen Kolbenoberteil (a) und -unterteil (b) ein auswechselbarer Zwischenkörper (Ring c) eingesetzt ist, durch den die Gesamtlänge des Kolbens und damit die Größe des Kompressionsraumes bestimmt wird. Two-part piston for internal combustion engines, characterized in that an exchangeable intermediate body (ring c ) is inserted between the piston upper part (a) and lower part (b) , by means of which the total length of the piston and thus the size of the compression space is determined.
