Description

Ölstandsicherung für Kolbenverdichter Die Erfindung bezieht sich auf Kolbenverdichter, deren Schmierung durch Eintaucrl-n der Schubstange bzw. ihrer rückwärtigen Verlängerung in den am Grunde des Kurbelgehäuses befindlichen Ölsumpf bewirkt wird, und betrifft eine Ausbildung des Gehäuses, durch die der richtige Stand des Ölspiegels gewährleistet wird.Oil level protection for reciprocating compressors The invention relates to Piston compressors, their lubrication by Eintaucrl-n the push rod or their rear extension in the oil sump located at the bottom of the crankcase is effected, and relates to a design of the housing through which the correct Level of the oil level is guaranteed.

Bei bekannten Ausführungen wird der ölsumpf durch eine quer durch das Kurbelg e 'häuse laufende Scheidewand begrenzt, hinter der sich eine Abflußöffnung befindet, durch die das von den bewegten Teilen herablaufende Öl der Schmierpumpe wieder zugeleitet wird.In known designs, the oil sump is crossed by a the crankcase delimits the partition wall, behind which there is a drainage opening through which the oil of the lubrication pump running down from the moving parts is fed back.

Räumliche Verhältnisse zwingen vielfach dazu, die Scheidewand. so anzuordnen, daß die durch den Kurbelumlauf entstehende Ölflutwelle diese Scheidewand überspült. Dadurch wird ein übermäßig starker Abfluß des Öles hervorgerufen, so daß beim Stillsetzen des Verdichters der Ölspiegel nicht mit der Oberkante der Scheidewand in gleicher Höhe, sondern erheblich unter ihr steht. Bei erneutem Anlaufen des Verdichters ergibt sich hieraus unzulängliche Schmierung.Spatial conditions often compel the partition. so to arrange that the oil surge caused by the crank circulation this septum flooded. This causes excessive drainage of the oil, see above that when the compressor is stopped, the oil level does not line up with the upper edge of the septum at the same level, but considerably below it. When the compressor starts up again this results in inadequate lubrication.

Dem abzuhelfen, ist der Zweck der Erfindung. Die Abb. i und 2 der Zeichnung zeigen zwei Lösungsbeispiele des Erfindungsgedankens.To remedy this is the purpose of the invention. Figs. I and 2 of Drawings show two examples of solutions for the inventive concept.

Nach der Abb. i wird dem Ölablauf R des Kolbenverdichters, der durch die Scheidewand b von dem Ölsumpf getrennt ist, eine höhere Zwischenwand c vorgelagert, die von der Ölflutwelle, die das Kurbelspiel erzeugt, nicht überflutet werden kann. Durchbrechungen d in der Wand c stellen die Verbindung zwischen dem Ölsumpf und dem zwischen den Wänden b und c befindlichen Raum her.According to Fig. I, the oil drain R of the reciprocating compressor, which runs through the partition b is separated from the oil sump, a higher partition c in front, which cannot be flooded by the oil surge that generates the crank play. Openings d in the wall c provide the connection between the oil sump and the space between walls b and c.

Nach der Abb. 2 mündet der Ölablauf a in ein den Ölablauf schutzkappenartig überdekkendes Gehäusee, das seinerseits mit dem Ölsumpf über Öffnungen f in Verbindung steht. Durch diese Anordnung wird die Öl; bewegung nur gedämpft auf den Raum innerhalb des Gehäuses e übertragen, so daß ein Überschwappen größerer Ölmengen in den Ablauf a und damit ein unzulässiges Absinken des Ölstandes vermieden wird.According to Fig. 2, the oil drain a opens into a protective cap like the oil drain Covering housing, which in turn communicates with the oil sump via openings f stands. Through this arrangement the oil; movement only dampened on the space within of the housing e transferred, so that a spill over larger amounts of oil in the drain a and thus an impermissible drop in the oil level is avoided.
