Description

Vom Ladedruck der Brennkraftmaschine beeinflußter Öldruckregler für Schmierölpumpen Es sind Schmierölverteiler zum Verteilen kleinster Ölmengen verschiedenster Bauart bekannt. Sie dienen insbesondere zur Schmierung der Steuerungsteile von schiebergesteuerten Brennkraftmaschinen. Die Ölverteiler sind drehzahlabhängig und abhängig vom Öldruck, da sich im Öl Luftblasen befinden und dieses Öl-Luft-Gemisch kompressibel ist. Bei derartigen Anordnungen besteht der Nachteil. daß der Ölverbrauch bei -geringer Belastung und hoher Drehzahl des Motors zu hoch wird.Oil pressure regulator influenced by the boost pressure of the internal combustion engine for Lubricating oil pumps There are lubricating oil distributors for distributing the smallest amounts of oil of the most varied Design known. They are used in particular to lubricate the control parts of slide-controlled valves Internal combustion engines. The oil distributors are speed-dependent and dependent on the oil pressure, because there are air bubbles in the oil and this oil-air mixture is compressible. at such arrangements have the disadvantage. that the oil consumption at -low load and high engine speed becomes too high.

Der Gegenstand der Erfindung betrifft einen Öldruckregler für derartige Schmierölverteiler, die von der Drehzahl und dem Öldruck abhängig sind. Der Öldruckregler besitzt außer der zur ladeluftabhängigen Steuerung vorgesehenen Membran eine vom Öldruck beeinflußte und diesen 'steuernde Membran, zwischen denen ein Verbindungsstück sowie ein unter atmosphärischem Bodendruck stehender, nach außen abgedichteter Raum angeordnet sind.The object of the invention relates to an oil pressure regulator for such Lubricating oil distributors, which are dependent on the speed and the oil pressure. The oil pressure regulator In addition to the membrane provided for charge air-dependent control, it has a from Oil pressure influenced and these 'controlling diaphragm, between which a connector as well as a room that is under atmospheric pressure and is sealed from the outside are arranged.

.In der Zeichnung ist schematisch ein Ausführungsbeispiel der Erfindung dargestellt. Schmierölv erteilerbckannter Bauart I bis VI sind an eine Öldruckleitung i angeschlossen. Das von den Schmierölverteilern I bis VI dosierte Öl wird über Leitungen a', a" usw. den Schmierstellen zugeführt. In die Öldruckleitung i wird ein Gehäuse 3 eingesetzt, das zwei Membranen ¢ und i. aufweisf, von denen die Membran q. mit einem Steuerventil 6 und die Membran 5 mit einer Feder 7 verbunden ist. Die Membran 4. wird vom Öl aus der Öldruckleitung i, während die Membran 5 von der Ladeluft beaufschlagt wird. Die Membranen 4 und 5 stehen durch ein Verbindungsteil 8 in kraftschlüssiger Verbindung. Tritt durch die Leitung i' vorn Ölkreislauf des Motors Öl in das Gehäuse ein, so liegt das Steuerv@:ntil 6 zunächst am Gehäuse an. Nimmt der Öldruck zu, so wird die Membran entgegen dem Druck der Feder ; ausgelenkt, und zwar so lange, bis ein Gleichgewichtszustand zwischen der vom Öldruck auf die Membran d. und von der Feder und dem der durch die Leitung 9 zugeführten Ladeluft besteht. Ändert sich diese Größe, so wird das Steuerventil 6 entsprechend verschoben und somit der Öldruck in der Leitung i geändert. Um zu vermeiden, daß bei Änderung der dcii Regler umgebenden Atmosphäre an den Membranen eine sich aus der zwischen den Membranen bestehenden Flächendifferenz ergebende Kraft (auf das Steuerventil) wirkt, wird der zwischen den Membranen befindliche Raum nach außen abgedichtet, so daß. die darin befindliche Luft unabhängig von der umgebenden Atmosphäre gleichen Druck behalt.. In the drawing is a schematic embodiment of the invention shown. Lubricating oil distributors of types I to VI are connected to an oil pressure line i connected. The oil metered by the lubricating oil distributors I to VI is over Lines a ', a "etc. are fed to the lubrication points a housing 3 is used, the two membranes ¢ and i. aufweisf, of which the membrane q. is connected to a control valve 6 and the membrane 5 to a spring 7. the Diaphragm 4th is from the oil from the oil pressure line i, while diaphragm 5 is from the charge air is applied. The membranes 4 and 5 are frictionally engaged by a connecting part 8 Link. If oil enters the housing through line i 'in the front oil circuit of the engine on, the control valve 6 initially rests on the housing. Takes the oil pressure increases, so the membrane is against the pressure of the spring; deflected, and until a state of equilibrium between the oil pressure on the membrane d. and of the spring and that of the charge air supplied through line 9. If this size changes, the control valve 6 is shifted accordingly and thus the oil pressure in line i changed. In order to avoid that when changing the dcii regulator surrounding atmosphere on the membranes a result from the between the The force resulting from the diaphragms (on the control valve) acts, the space between the membranes is sealed to the outside, so that. the air in it has the same pressure regardless of the surrounding atmosphere keep.
