Es sind Bauarten für Öldruckservomotoren für selbsttätige hydraulische Regler bekannt, bei welchen jede Seite eines doppelt wirkenden Arbeitskolbens mit einer dauernd ölfördernden Pumpe durch eine Rohrleitung oder einen Kanal in Verbindung steht. Die Steuerung dieser Öldruckservomotoren geschieht dabei bekanntermaßen dadurch, daß je nach der gewünschten Bewegungsreibung desServomotorkolbens auf der einen oder der anderen *»There are known types of oil pressure servomotors for automatic hydraulic regulators, in which each side of a double-acting working piston with a permanently oil-pumping Pump through a pipeline or a channel in communication. The control As is known, this oil pressure servo motor takes place in that, depending on the desired movement friction of the servo motor piston on one or the other * »
Seite des Zylinders eine öffnung freigegeben wird, aus welcher das von der Pumpe gelieferte Drucköl sowie das aus dem anliegenden Arbeitsraum des1 Zylinders etwa zurückströmende öl entweichen kann.Side of the cylinder, an opening is released, can escape from which the pressure oil delivered by the pump as well as the approximately flowing back from the adjacent working chamber of the cylinder 1 oil.
Diese Art der Steuerung, welche lediglich das Freigeben und Verschließen zweier öffnungen erfordert, ist an sich sehr einfach. Die beschriebene Anordnung leidet jedoch anThis type of control, which only enables and closes two openings is very simple in itself. However, the arrangement described suffers
xo dem Mangel, daß zwei öldruckpumpen erforderlich sind, was eine unerwünschte Verwicklung der Einrichtung darstellt.xo the lack that two oil pressure pumps are required, which is an undesirable entanglement the establishment represents.
Erfindungsgemäß wird dieser Mangel dadurch beseitigt, daß an Stelle zweier öldruckpumpen eine einzige mit drei Rädern ausgeführte Zahnradpumpe zur Verwendung gelangt, wobei die eine Seite der Zahnrad- oder Kapselpumpe das öl für die eine Zylinderseite liefert. Die Abbildung stellt eine Ausführung des erfindungsgemäßen Öldruckservomotors dar. K ist das Gehäuse der Zahnradpumpe, in welchem die drei Räder T U V in der Pfeilrichtung kreisen, α und b sind dementsprechend die Saugstellen der Pumpe, welche durch Saugrohre mit dem ölbehälter in Verbindung gebracht werden. Andererseits sindAccording to the invention, this deficiency is eliminated in that, instead of two oil pressure pumps, a single gear pump designed with three wheels is used, one side of the gear or capsule pump supplying the oil for one side of the cylinder. The figure shows an embodiment of the oil pressure servomotor according to the invention. K is the housing of the gear pump, in which the three wheels TUV rotate in the direction of the arrow, α and b are accordingly the suction points of the pump, which are connected to the oil container through suction pipes. On the other hand are
c und d die beiden Druckseiten der Pumpe. Die aus den beiden Räumen c und d austretenden Druckölströme werden nun getrennt in je eine Rohrleitung eingeleitet und den beiden Seiten eines doppelt wirkenden Arbeitszylinders Z zugeführt. V sind zwei an jede der vorgenannten Rohrleitungen angeschlossene Steuerventile, mit denen je nach Bedarf eine oder beide Rohrleitungen und die damit zusammenhangenden öidruckräume geöffnet werden können. Durch Steuerung dieser Ventile wird dem Kolben im Arbeitszylinder Z die gewünschte Bewegung erteilt. Der Erfmdungsgegenstand ist eine Anordnung einer Öldruckservomotorpumpe einfachster Art. c and d the two pressure sides of the pump. The pressurized oil flows emerging from the two spaces c and d are now introduced separately into a pipe and fed to the two sides of a double-acting working cylinder Z. V are two control valves connected to each of the aforementioned pipelines, with which one or both pipelines and the associated oil pressure spaces can be opened as required. By controlling these valves, the piston in the working cylinder Z is given the desired movement. The subject matter of the invention is an arrangement of an oil pressure servomotor pump of the simplest type.
