Description

Zweitaktbrennkraftmaschine mit seitlich angebauter Kolbenluftpumpe Die Erfindung betrifft eine besonders zweckmäßige und einfache Ausgestaltung von Zweitaktbrennkraftmaschinen mit seitlich angebauter Kolbenluftpumpe. Es wird dabei die Aufgabe gelöst, die seitlichen Anbauteile, nämlich Kolbenluftpumpe und den an sich bekannterweise auf der gleichen Seite angeordneten Auspufftopf, so miteinander zu verbinden, daß der zwischen ihnen verbleibende Raum ebenfalls für die Hebung des Wirtschaftswertes der Maschine nutzbar gemacht wird. Diese Aufgabe wird dadurch gelöst, daß der Zwischenraum zwischen Pumpe und Auspufftopf ummantelt und als Beruhigungs- und Ansaugeraum ausgebildet wird.Two-stroke internal combustion engine with a piston air pump mounted on the side The invention relates to a particularly useful and simple embodiment of Two-stroke internal combustion engines with a piston air pump attached to the side. It will be there the task solved, the side attachments, namely piston air pump and the is known to be arranged on the same side of the muffler, so with each other to connect that the space remaining between them is also for the uplift the economic value of the machine is made usable. This is what makes this job solved that the space between the pump and the muffler is encased and used as a calming and suction space is formed.

Ferner kann man erfindungsgemäß die Leitungen für die Druck- und Saugluft oberhalb des Pumpenzylinders legen. Dadurch erreicht man, daß das Luftpumpengehäuse nicht breiter wird als das durch den äußeren Durchmesser des Pumpenzylinders gegebene Maß. Dies ist besonders wichtig für mehrzylindrige Motoren, denn bei diesen besteht ein dringendes Bedürfnis, die Breite jedes Zylinders in der Richtung der Kurbelachse möglichst klein zu halten.Furthermore, according to the invention, the lines for the compressed air and suction air can be used place above the pump cylinder. This achieves that the air pump housing does not become wider than that given by the outer diameter of the pump cylinder Measure. This is particularly important for multi-cylinder engines, because with these there is an urgent need, the width of each cylinder in the direction of the crank axis to keep it as small as possible.

Die Zeichnung gibt eine beispielsweise Ausführung der Erfindung wieder.The drawing shows an example embodiment of the invention.

Abb. z ist ein Hauptschnitt durch die Achsen des Motors und der Luftpumpe; Abb. 2 zeigt eine Ansicht in der Richtung des Pfeiles A auf das Pumpengehäuse, wobei man sich den Pumpendeckelabgenommendenkt; Abb. 3 zeigt einen Schnitt nach der Linie C-D; Abb. q. zeigt einen Schnitt nach der gebrochenen Linie E -F; Abb. 5 zeigt den Luftpumpendeckel in Pfeilrichtung B gesehen. An das Zylindergestell a des Zweitaktmotors ist die Luftpumpe b angebaut, welche unterhalb des Auspufftopfes c liegt. Zwischen Auspufftopf und dem Luftpumpengehäuse liegt der durch die Ummantelung d geschaffene Ansaugeraum e. Unmittelbar über dem Luftpumpenzylinder liegen die Ansauge- und Druckleitungen f und k, die zu den Spülschlitzen führen. Die mit Pfeilen versehenen Linien deuten die Wege der Saug- und der Druckluft an. Die Abb. 2 bis q. zeigen deutlich die erfindungsgemäße Ausgestaltung und Führung der Saug- und Druckleitungen zu der Luftpumpe. Aus der Abb. 2 geht deutlich hervor, daß das Pumpengehäuse trotz Einbaus der Luftleitungen nur so breit wird, wie es der größte Durchmesser des Pumpenzylinders verlangt. In Abb. 5 sind die Saugleitungen f, die Druckleitung g und die Ventilklappen i zu erkennen.Fig. Z is a main section through the axes of the motor and the air pump; Figure 2 is a view in the direction of arrow A of the pump housing with the pump cover removed; Fig. 3 shows a section along the line CD; Fig.q. shows a section along the broken line E -F; Fig. 5 shows the air pump cover seen in the direction of arrow B. The air pump b is attached to the cylinder frame a of the two-stroke engine and is located below the muffler c. The suction space e created by the casing d is located between the muffler and the air pump housing. The suction and pressure lines f and k, which lead to the flushing slots, are located directly above the air pump cylinder. The lines with arrows indicate the paths of the suction and compressed air. Fig. 2 to q. clearly show the inventive design and routing of the suction and pressure lines to the air pump. From Fig. 2 it is clear that the pump housing is only as wide as the largest diameter of the pump cylinder requires, despite the installation of the air lines. In Fig. 5 the suction lines f, the pressure line g and the valve flaps i can be seen.
