 und zum sanften Druckwechsel in der Nähe des oberen Totpunktes beiträgt. Der Durchmesser des Kolbens e wird dem erforderlichen   Ausgleichsdruck   entsprechend bemessen. 



   Die Fig. 2 zeigt eine Anordnung bei der die Massenwirkung der hin und her gehenden Teile der Spülluftpumpe sowohl nach oben als auch nach unten ausgeglichen wird. Zwischen die Niederdruckstafe f und die Hochdruckstufe g der Einblasepumpe ist zu diesem Zweck eine   Mitteldruckstufe r   eingeschaltet. 



   Der Kolben e ist als doppeltwirkender Kolben ausgeführt. Nach oben wirkt er als 
 EMI2.1 
 getrieben. 



   Bei der Anordnung nach der Fig. 1 wird nur der Beschleunigungsdruck der Massen nach oben durch den nach oben drückenden Kolben e ausgeglichen, bei der Anordnung nach Fig. 2 die Massenwirkung der hin und her gehenden Teile sowohl nach oben, durch den im Niederdruckzylinder y herrschenden Druck, als auch nach unten, durch den Druck im   Mitteldrnckzylinder r.   



   PATENT-ANSPRÜCHE :
1. Anordnung von doppeltwirkenden Spülluftpumpen und zwei-oder mehrstufigen Einblaseluftpumpen bei raschlaufenden   Zweitaktverbrennungskra. f'Maschinen,   dadurch gekennzeichnet, dass der Niederdruckkolben der Einblaseluftpnmpe e. nseitig wirkend zwischen dem doppeltwirkenden   Sptilluftpumpenkoll) en und   dem das ganze System antreibenden Kurbelgetriebe als Ausgleichskolben angeordnet ist und der Druckhub dieser Niederdruckstufe mit demjenigen der einen   Spülluftpumpenseite   zusammenfällt.

 and contributes to the gentle pressure change near top dead center. The diameter of the piston e is dimensioned according to the required equalization pressure.



   Fig. 2 shows an arrangement in which the mass effect of the reciprocating parts of the scavenging air pump is balanced both upwards and downwards. For this purpose, a medium pressure stage r is switched on between the low pressure stage f and the high pressure stage g of the injection pump.



   The piston e is designed as a double-acting piston. Upwards it acts as a
 EMI2.1
 driven.



   In the arrangement according to FIG. 1, only the acceleration pressure of the masses upwards is compensated by the upwardly pressing piston e; in the arrangement according to FIG. 2, the mass effect of the reciprocating parts both upwards through that prevailing in the low pressure cylinder y Pressure, as well as downwards, through the pressure in the medium pressure cylinder r.



   PATENT CLAIMS:
1. Arrangement of double-acting scavenging air pumps and two- or multi-stage injection air pumps with fast-running two-stroke combustion engines. f 'machines, characterized in that the low-pressure piston of the injection air pump e. Acting on the side between the double-acting flushing air pump cylinder and the crank mechanism driving the entire system, it is arranged as a compensating piston and the pressure stroke of this low-pressure stage coincides with that of one side of the flushing air pump.

2. Anordnung nach Anspruch 1 bei dreistufiger Einblaseluftpumpe, dadurch gekennzeichnet, dass die Nieder-und Mitteldruck-kolben der Einblaseluftpumpe zu einem doppeltwirkenden Stufenkolben vereinigt zwischen dem doppeltwirkenden Spülluftpumpenkolben und dem das ganze System antreibenden Kurbelgetriebe als Ausgleichskolben angeordnet sind, wobei der Druckhub der Niederdruckstufe mit demjenigen der einen Spülluftpumpen- seite und der Druckbub der Mitteidruckstufe mit demjenigen der anderen Spülluftpumpenseite zusammenfällt. 2. Arrangement according to claim 1 with a three-stage air injection pump, characterized in that the low and medium pressure pistons of the air injection pump combined to form a double-acting step piston between the double-acting scavenging air pump piston and the crank mechanism driving the entire system are arranged as a compensating piston, with the pressure stroke of the low pressure stage with that of one side of the purge air pump and the pressure boom of the medium pressure stage coincides with that of the other side of the purge air pump.
