Description

Uin die Leistung einer Za,_itaktiiisscliiiie zu erhöhen, hat man versucht, daß die Überström- und Auslaßkanäle so gesteuert werden, daß beim Kompressionshub der Auslaßkanal eher schließt als der Überströmkanal, beim Arbeitshub dagegen der Anlaßkanal eher geöffnet als der Überströmkanal.In order to increase the performance of a Za, _itaktiiisscliiiie, attempts have been made that the overflow and outlet channels are controlled so that the compression stroke the outlet channel closes sooner than the overflow channel, on the other hand the The starter port is more open than the transfer port.

Dieses wurde erreicht mit Hilfe von zwei voneinander getrennten Kolben in einem gemeinsamen Verbrennungsraum, die durch ein Gabelpleuel angetrieben werden.This was achieved with the help of two separate pistons in a common combustion chamber, which are driven by a fork connecting rod.

Die Erfindung bezweckt, das gleiche Prinzip mittels eines Kolbens zu erreichen.The invention aims to implement the same principle by means of a piston to reach.

Der Kolben besteht aus zwei Hälften a und ai, wie aus den Abb. i und 2 zu ersehen ist. Die beiden Kolbenhälften a und a1 werden durch ein T-Pleuel b angetrieben. Die Schlitze c im T-Pleuel b greifen in Gleitsteine d, die mit ihren runden Lagerenden e in jeder Kolbenhälfte beweglich gelagert sind. Zwischen beiden aufeinander gleitenden Flächen der Kolbenhälften a und ai ist eine Dichtungsplatte feingelegt, die durch Federn h angepreßt wird. Die Kolbenringe g sind ebenfalls geteilt und werden mit Federn i an die Zylinder-, wand angedrückt.The piston consists of two halves a and ai, as can be seen in Figs. I and 2. The two piston halves a and a1 are driven by a T-connecting rod b. The slots c in the T-connecting rod b engage in sliding blocks d, which are movably mounted with their round bearing ends e in each piston half. Between the two surfaces of the piston halves a and ai that slide on one another, a sealing plate is finely placed, which is pressed by springs h. The piston rings g are also divided and are pressed against the cylinder wall with springs i.

Abb. i zeigt den geteilten Kolben beim Arbeits- und Auspuffhub; Abb. 2 zeigt den geteilten Koll>cß beine Alisaugä und Kompressionshub; Abb. 3 zeigt das T-Pleuel b mit den in den Schlitzenc gelagerten Gleitsteinen d und deren runden Lagerenden e ; Abb. 4 zeigt die Anbringung der Dichtungsplatte f und der Kolbenringe g so-%i,ie die :Anordnung der Federn Az und i; Abb. 5 zeigt den Gleitstein d mit den runden Lagerenden e.Fig. I shows the split piston on the working and exhaust stroke; Fig. 2 shows the split collapse legs and compression stroke; Fig. 3 shows the T-connecting rod b with the sliding blocks d mounted in the slotsc and their round bearing ends e; Fig. 4 shows the attachment of the sealing plate f and the piston rings g so-% i, ie the: arrangement of the springs Az and i; Fig. 5 shows the sliding block d with the round bearing ends e.
