Description

Die Erfindung betrifft eine weitere Ausbildung der ebenen Steuerfläche für Flüssigkeitsgetriebe mit Schiefscheibe. Nach der im Hauptpatent angegebenen Vorrichtung werden zwischen dem Druckraum und den Entlastungsräumen Drosselnuten vorgesehen, um den Druck der den Entlastungsräumen zufließenden Ölmenge zu verringern und um diese ölmenge in Abhängigkeit von der abfließenden Leckölmenge zu bringen, wodurch ein Druckgefälle entsteht, durch das die Steuerflächen in geringem Abstand voneinander gehalten werden. Nach der Erfindung werden die Drosselstellen dadurch erzeugt, daß Dichtungsringe oder -Segmente in Nuten der einen Steuerfläche angeordnet und durch federnde Unterlagen gegen die andere Steuerfläche gedruckt werden.The invention relates to a further embodiment of the flat control surface for fluid transmissions with swash plate. According to the device specified in the main patent Throttle grooves are provided between the pressure chamber and the relief chambers in order to to reduce the pressure of the amount of oil flowing into the relief chambers and to this amount of oil depends on the drainage Bring leakage oil, which creates a pressure gradient through which the control surfaces are at a small distance from each other being held. According to the invention, the throttling points are generated by that sealing rings or segments arranged in grooves of a control surface and through resilient pads against the other control surface to be printed.

Diese Dichtungsringe dichten gegenüber ao dem hohen Flüssigkeitsdruck im Getriebe nur unvollkommen· ab, weil durch die Bearbeitung der Getriebeteile und der Dichtungsringe immer kleine Spalten entstehen, durch welche das Öl Hndurchtreten kann. Es bilden sich also auch hier Drosselspalten, deren Wirkung mit denjenigen im Hauptpatent übereinstimmt. Die Ausbildung der Dichtungsringe kann in verschiedener Weise erfolgen.These sealing rings only seal against the high fluid pressure in the transmission imperfect because of the machining of the gear parts and the sealing rings small gaps always appear through which the oil can pass. It is formed So here too throttle gaps, the effect of which corresponds to that in the main patent. The sealing rings can be designed in various ways.

Die Fig. 1 und 2 zeigen im Schnitt und in Aufsicht mehrere Äusführungsformen.FIGS. 1 and 2 show several embodiments in section and in plan view.

Der Druckraum 40 in dem feststehenden Steuerspiegel 38 wird nach der linken Hälfte der Fig. 1 durch Ringe 50 abgedichtet, welche in Aussparungen 49 in dem Zylinderblock 14 untergebracht sind. Nach der Ausführung in 3S der rechten Hälfte der Fig. 1 liegen die Dichtungsringe 50° zum Teil im Zylinderblock, und zum Teil im feststehenden Steuerspiegel. Der Druckraum 40 und der Saugraμm*44 werden außen und innen durch die Flächen 72 und 73 des Steuerspiegels begrenzt. Gegen diese Flächen legen sich die Dichtungsringe 50, die durch Federn angedrückt werden können. In der rechten Hälfte der Fig. 2 sind Nuten 74 und 75 vorgesehen, in welchen die durchgehenden Dichtungsringe 500 eingebettet sind.The pressure chamber 40 in the fixed control plate 38 is sealed off according to the left half of FIG. 1 by rings 50 which are accommodated in recesses 49 in the cylinder block 14. After executing in S 3 the right half of Fig. 1 the sealing rings 50 ° lie partly in the cylinder block, and partly in the stationary valve plate. The pressure chamber 40 and the suction chamber * 44 are bounded outside and inside by the surfaces 72 and 73 of the control plate. The sealing rings 50, which can be pressed by springs, lie against these surfaces. In the right half of FIG. 2, grooves 74 and 75 are provided, in which the continuous sealing rings 50 0 are embedded.
