Description
Einrichtungen zum Schmieren der Kolben von Kolbenmaschinen, bei denen das Schmiermittel vom Kolben her unter Druck an die Kolbenringe gebracht wurde, sind bekannt. Die Zuführung des Schmiermittels erfolgt entweder pneumatisch oder mechanisch ähnlich der Wirkungsweise üblicher Schmierpressen.Devices for lubricating the pistons of reciprocating machines in which the lubricant was brought under pressure from the piston to the piston rings, are known. The lubricant is supplied either pneumatically or mechanically similar to the mode of operation of conventional grease guns.
Man hat auch bereits vorgeschlagen, innerhalb des Leitungszuges, meist im Kolben selbst zwischen Zuführleitungen und Austrittsöffnungen, Rückschlagventile einzubauen, denen die Aufgabe zugewiesen wurde, die Schmiermittelleitung gegen den Zylindern hin abzusperren, um den Zutritt des pneumatischen Druckmittels bzw. Leerlaufen der Leitungen zu verhindern. Diese Rückschlagventile erfordern üblicherweise nur einen verhältnismäßig geringen Druck für ihre im Sinne der Austrittsbewegung des Schmiermittels gerichtete Offnungsbewegung.It has also already been suggested, mostly within the cable run in the piston itself between supply lines and outlet openings, check valves to be installed, who have been assigned the task of moving the lubricant line against the Shut off cylinders to allow the pneumatic pressure medium to enter or to run empty to prevent the lines. These check valves usually only require a relatively low pressure for their in the sense of the exit movement of the Lubricant-directed opening movement.
Um eine möglichst einwandfreie Schmierung zu gewährleisten, schlägt die Erfindung vor, zur Zuführung des Schmiermittels zur Schmierstelle: unter Hochdruck ein an sich bekanntes Öldruckgesteuertes Einspritzventil im Kalben frei gegen die Zylinderwand gerichtet anzuordnen.. Die Einspritzmündungen der Ventile sollen, in einem zwischen den Kolbenringen in dem Kolbenumfang eingearbeiteten Ringraum liegen.. Eine gute Verteilung des Schmiermittels ist bei Anwendung der Erfindung auch dann schon zu erreichen, wenn bei liegend arbeitenden Maschinen nur eine Schmierstelle an der höchsten Stelle des Ringraumes vorgesehen ist.To ensure the best possible lubrication, suggests the invention for the supply of the lubricant to the lubrication point: under high pressure a known oil pressure-controlled injection valve in the calving free against the Arrange the cylinder wall facing. The injection ports of the valves should, in an annular space worked into the piston circumference between the piston rings .. A good distribution of the lubricant is also then when the invention is used Can already be reached if there is only one lubrication point on horizontally working machines is provided at the highest point of the annulus.
Da die notwendigen hohen Einspritzdrücke leicht Leckverluste in den Zuführungsleitungen herbeiführen können, soll, was ebenfalls im Rahmen der Erfindung liegt, die Überleitung des Schmiermittels von den festen zu den bewegten Maschinenteilen über Gelenkschwingen, nicht wie üblich mit Hilfe von Stopfbüchsen, sondern über elastische Rohre: erfolgen. Die Zeichnung gibt in Fig. i die bekannte Ventilanordnung, in Fig.2 ein Ausführungsbeispiel der Neuerung und in Fig. 3 die Schwingenanordnung wieder.Since the necessary high injection pressures can easily leak into the Can bring about supply lines, which should also be within the scope of the invention is the transfer of the lubricant from the fixed to the moving machine parts via articulated rockers, not as usual with the help of stuffing boxes, but via elastic tubes: made. The drawing shows in Fig. I the known valve arrangement, in Fig. 2 an embodiment of the innovation and in Fig. 3 the rocker arrangement again.
Wie die übliche Anordnung nach Fig. i erkennen läßt, öffnet das im Kolben2 eingebauteRücksch.lagventil i in Richtung des Schmiermittelflusses entgegen dem Druck einer schwachen Feder 3 und läßt dieses bei 4 herausquellen. Im Gegensatz dazu wird das Schmiermittel (vgl. Fig. 2) nach der Erfindung unter hohem Druck in das Einspritzventil 5 geführt und aus diesem, nachdem der Stößel 6 die Düse freigegeben hat, in den Ringraum 7 des Kolbens :2 gespritzt.As the usual arrangement according to FIG. I shows, it opens in the Piston 2 built-in check valve i in the opposite direction to the flow of lubricant the pressure of a weak spring 3 and lets it swell out at 4. In contrast for this purpose, the lubricant (see. Fig. 2) according to the invention under high pressure in the injection valve 5 out and out of this after the plunger 6 has released the nozzle has injected into the annular space 7 of the piston: 2.
Fig. 3 zeigt schematisch die an Stelle von Stopfbüchsen vorgesehenen elastischen Rohrspiralen B.Fig. 3 shows schematically those provided instead of stuffing boxes elastic pipe spirals B.
