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.
