Eine vorteilhafte Weiterbildung der Erfindung bewirkt, daß der Lader selbst als Verteiler der Ladeluft über die Länge des Motors fungiert. Damit erübrigen sich zusätzliche Ver teilerleitungen.An advantageous development of the invention causes the charger itself as a distributor of the charge air over the length of the engine acts. This eliminates the need for additional ver partial lines.
Eine vorteilhafte Ausbildung der Erfindung schafft einen Druckausgleich zwischen den einzelnen Zylindern, falls dieser durch den Lader selbst nicht hinreichend gewähr leistet ist.An advantageous embodiment of the invention creates one Pressure equalization between the individual cylinders, if this is not adequately guaranteed by the loader itself is accomplished.
Die erfindungsgemäße Lösung gestattet eine platzsparende Aufladevorrichtung für Ein- und Zweizylindermotoren.The solution according to the invention allows a space-saving Charging device for one and two-cylinder engines.

Bei dem in Fig. 1 und 2 dargestellten Lader 1 handelt es sich um einen bekannten Flügelzellenlader. Dieser weist einen Läufer 9 mit radial stehenden, federbelasteten und in Nuten geführten Schaufeln 10 auf. Der Läufer 9 dreht sich in einem Gehäuse 2, das zugleich Ladeluftleitung ist. Er ist mit seinen Lagerzapfen 14, 14a in Wälzlagern 12, 12a gelagert, die mittels Radialdichtungen 13, 13a gegen über dem Läufer 9 abgedichtet sind. Auf dem Lagerzapfen 14a ist eine Keilriemenscheibe 15 mittels Keil 16 und Sechskantschraube 17 befestigt. The loader 1 shown in FIGS. 1 and 2 is a known vane loader. This has a rotor 9 with radially standing, spring-loaded blades 10 which are guided in grooves. The rotor 9 rotates in a housing 2 , which is also the charge air line. It is mounted with its journals 14 , 14 a in roller bearings 12 , 12 a, which are sealed against the rotor 9 by means of radial seals 13 , 13 a. On the bearing pin 14 a, a V-belt pulley 15 is fastened by means of wedge 16 and hexagon screw 17 .
Die Ladeluftleitung 3 mit den beiden Abzweigen 4 ist für einen Zweizylindermotor ausgelegt. Die beiden Abzweige 4 sind durch eine Verbindungsleitung 5 verbunden, die ein stückig mit der Ladeluftleitung 3 gegossen ist. In dem ab triebsfernen Ende der Verbindungsleitung 5 befindet sich eine Gewindebohrung 18 für die Anbringung des in Fig. 3 dargestellten Sicherheitsventils 6. An diesem ist ein Ab blaseluftauslaß 19 angeordnet, der sich in Strömungsver bindung mit einem Abblaselufteinlaß 20 am Saugstutzen 21 des Laders befindet.The charge air line 3 with the two branches 4 is designed for a two-cylinder engine. The two branches 4 are connected by a connecting line 5 , which is cast in one piece with the charge air line 3 . In the end remote from the connecting line 5 there is a threaded bore 18 for the attachment of the safety valve 6 shown in FIG. 3. From this, a blast air outlet 19 is arranged, which is in flow connection with a blow-off air inlet 20 on the suction nozzle 21 of the charger.
Die erfindungsgemäße Anordnung funktioniert folgendermaßen:
Der Lader 1 wird von dem Motor über einen Keilriemen 8 und
die Keilriemenscheibe 15 angetrieben. Er saugt die Ver
brennungsluft über den Saugstutzen 21 an, verdichtet die
selbe und fördert die verdichtete Luft in die Ladeluftlei
tung 3 mit ihren Abzweigen 4, die zum nicht dargestellten
Motor führen. Druckschwankungen zwischen diesen Abzweigen
werden durch die Verbindungsleitung 5 weitgehend ausge
glichen. Das Sicherheitsventil 6 dient zur Begrenzung des
Ladeluftdruckes. Die abgeblasene Ladeluft wird über den
Abblasluftauslaß 19 zum Abblaslufteinlaß 20 zurück in den
Saugstutzen 21 geführt. Weiterhin mündet im Saugstutzen 21
eine nicht dargestellte Entlüftungsleitung des Motors,
durch die öldampfhaltige Gase dem Lader zugeführt werden
und dessen Schmierung bewirken.The arrangement according to the invention works as follows:
The loader 1 is driven by the engine via a V-belt 8 and the V-belt pulley 15 . He sucks the combustion air through the suction port 21 , compresses the same and promotes the compressed air into the charge air duct 3 with its branches 4 , which lead to the engine, not shown. Pressure fluctuations between these branches are largely compensated for by the connecting line 5 . The safety valve 6 serves to limit the charge air pressure. The blown-off charge air is guided back into the suction port 21 via the blow-off air outlet 19 to the blow-off air inlet 20 . Furthermore, a ventilation line (not shown) of the engine opens through the suction nozzle 21 , through which gases containing oil vapor are fed to the charger and effect its lubrication.
Die erfindungsgemäße Laderanordnung führt zu einer kompak ten, leichten und kostengünstigen Aufladelösung, die sich auch an Ein- oder Zweizylindermotoren verwirklichen läßt.The loader arrangement according to the invention leads to a compact th, light and inexpensive charging solution that can also be realized on one or two-cylinder engines.
