Description

Luftpumpenanordnung für Zweitaktdieselmaschinen. Es ist bei Zweitaktbrennkraftmaschinen bekannt, drei Pumpenzylinder gleichachsig hintereinander anzuordnen und die auf einer gemeinsamen Kolbenstange sitzenden Kolben durch ein gemeinsames Kurbelgetriebe hin und her zu bewegen (Tandemanordnung). Dabei ist aber ein besonderer Kreuzkopf vorgesehen. Die Erfindung bezieht sich nun auf eine Luftpumpenanordnung für Zweitaktdieselmaschinen mit Spül-, Auflade- und Einblaseluftpumpe und besteht darin, daß die Aufladeluftpumpe als doppelt wirkende Kolbenpumpe in der Verlängerung der doppelt wirkenden Spülluftpumpe angeordnet und der Kreuzkopf des zum Antrieb der Spül- und Aufladepumpe dienenden Kurbelgetriebes als Niederdruckkolben der Einblaseluftpumpe ausgebildet ist.Air pump arrangement for two-stroke diesel engines. It is in two-stroke internal combustion engines known to arrange three pump cylinders on the same axis and one behind the other a common piston rod seated piston by a common crank mechanism to move back and forth (tandem arrangement). But there is a special crosshead intended. The invention now relates to an air pump arrangement for two-stroke diesel engines with flushing, charging and injection air pump and consists in that the charging air pump as a double-acting piston pump as an extension of the double-acting purge air pump arranged and the cross head of the to drive the flushing and charging pump serving Crank gear is designed as a low-pressure piston of the injection air pump.

Während die Kolben der Spül-. und Aufladepumpe Scheibenkolben darstellen, besitzt der Niederdruckkolben der Einblaseluftpumpe die Gestalt eines Tauchkolbens, an dem unmittelbar das Kurbelgetriebe angreift. Die Aufladepumpe kann dabei so ausgebildet sein, daß sie wahlweise aus der Außenluft oder aus dem Druckraum der Spülluftpumpe ansaugen kann.While the pistons do the flushing. and charging pump represent disc pistons, the low-pressure piston of the air injection pump has the shape of a plunger, which directly engages the crank mechanism. The charging pump can be designed in this way be that they either come from the outside air or from the pressure chamber of the scavenging air pump can suck in.

Die Zeichnung stellt ein Ausführungsbeispiel des Erfindungsgegenstandes dar.The drawing represents an embodiment of the subject matter of the invention represent.

i ist der Niederdruckkolben einer mehrstufigen Druckluftpumpe, die Druckluft für Einblase- oder Anlaßzwecke für eine nicht gezeichnete Verbrennungskraftmaschine liefert. An diesem Kolben ist eine Kolbenstange a befestigt, welche in ihrem mittleren Teil den Kolben 3 einer doppelt wirkenden Spülluftpumpe und an ihrem oberen Ende den Kolben 4 der doppelt wirkenden Aufladeluftpumpe trägt.i is the low pressure piston of a multi-stage compressed air pump, the Compressed air for blowing or starting purposes for an internal combustion engine, not shown supplies. A piston rod a is attached to this piston, which in its middle Part of the piston 3 of a double-acting scavenging air pump and at its upper end carries the piston 4 of the double-acting charge air pump.

5 ist der Zylinder der Spülluftpumpe und 6 derjenige der Aufladeluftpumpe. 7 ist die Saug- und S die Druckleitung der Spülluftpumpe, während 9 die Saug- und io die Druckleitung der Aufladeluftpumpe ist.5 is the cylinder of the scavenging air pump and 6 that of the supercharging air pump. 7 is the suction line and S is the pressure line of the scavenging air pump, while 9 is the suction line and io is the pressure line of the supercharging air pump.

Die Ausbildung kann so getroffen sein, daß die Aufladeluftpumpe unmittelbar aus der Außenluft durch das Einlaßrohr ii oder aus dem Druckraum 12 der Spülluftpumpe ansaugt. Dies kann durch entsprechende Einstellung des Dreiweghahns 13, .welcher zwischen den Leitungen ii und 12 angeordnet ist, geschehen.The training can be made so that the charge air pump directly from the outside air through the inlet pipe ii or from the pressure chamber 12 of the purge air pump sucks. This can be done by setting the three-way valve 13, .which is arranged between the lines ii and 12, done.
