Description

Zweitaktmotor mit gegen den Vorverdichtungsraum offenem Kurbelkasten. . Zur Verringerung des schädlichen Raumes der Kurbelkastenspülpumpe bei Zweitaktmotoren hat man verschiedene Wege eingeschlagen. Man hat den. Kurbelraum vom Vorverdichtungsraum durch besondere Vorrichtungen, beispielsweise Zwischenstücke mit Geradeführungen, sowie durch Anwendung von Stufenkolben zu trennen versucht. Oder man hat an Stelle des einfachen Kolbens einen Stufenkolben verwendet. Alle diese Vorrichtungen machen den Motor umständlich und bedingen Vergrößerung der reibenden und mit teuren Schmiermitteln zu versehenden Flächen.Two-stroke engine with the crankcase open towards the pre-compression chamber. . To reduce the harmful space of the crankcase flushing pump in two-stroke engines different paths have been taken. One has that. Crank chamber from the pre-compression chamber by special devices, for example intermediate pieces with straight guides, and tried to separate them by using graduated pistons. Or one has in place of the simple piston uses a stepped piston. Do all of these devices the engine cumbersome and require enlargement of the rubbing and expensive lubricants areas to be provided.

Gegenstand der Erfindung ist ein Zweitaktmotor, bei welchem der schädliche Raum der Kurbelkastenspülpumpe wirksam und in einfacher Weise unter Beibehaltung der üblichen Kolbenform dadurch verringert wird, daß im Kolben eine in der Zeichnung (Abb. r und 2) beispielsweise angedeutete Scheidewand c angeordnet ist und zur Verminderung des schädlichen Raumes unterhalb dieser Scheidewand feststehende, sich mit dem Kolben nicht bewegende Füllstücke b angebracht sind. Diese beiden Anordnungen ermöglichen gemeinschaftlich, daß der Zweck des Erfindungsgegenstandes erreicht wird.The invention is a two-stroke engine, in which the harmful Space of the crankcase scavenger pump effectively and easily while maintaining the usual piston shape is reduced by the fact that in the piston one in the drawing (Fig. R and 2) for example indicated partition c is arranged and to reduce of the harmful space underneath this septum fixed, with the piston non-moving filler pieces b are attached. These two arrangements allow jointly that the purpose of the subject matter of the invention is achieved.
