Abstract
Description
Die Erfindung betrifft einen Radialkolbenmotor nach dem Oberbegriff des Anspruchs 1.The invention relates to a radial piston engine according to the preamble of claim 1.
Ein Radialkolbenmotor dieser An ist
aus
Der Erfindung liegt die Aufgabe zugrunde, einen Radialkolbenmotor der eingangs angegebenen An so auszubilden, dass dessen Arbeitsweise verbessert wird.The invention is based on the object to design a radial piston motor of the type specified at the beginning, that its functioning will be improved.
Dies wird erfindungsgemäß durch die Merkmale im kennzeichnenden Teil des Anspruchs 1 erreicht. Dadurch, dass das Steuerelement nach Beendigung der Druckbeaufschlagung des Kolbens eine Verbindung mit dem Leckfluidraum im Gehäuse frei gibt, wird das aus dem Kolbenraum ausgestoßene Fluid in den Leckfluidraum des Gehäuses geleitet, von dem aus das Druckfluid über die Leckleitung vom Gehäuse zum Tank abgeführt wird. Hierdurch kann eine gesonderte Rücklaufleitung zwischen Zylinderdeckel und Tank entfallen, da das Druckfluid nach dem Arbeitshub eines Kolbens direkt in den Leckfluidraum des Gehäuses geleitet und von dort über die Leckleitung zum Tank abgeführt wird. Der Leckfluidraum des Gehäuses wirkt dämpfend auf den pulsierenden abfließenden Fluidstrom, der einer Dekompression ausgesetzt ist, wodurch eine schwingungsarme und somit geräuscharme Arbeitsweise des Radialkolbenmotors erzielt wird.This is done according to the invention the features in the characterizing part of claim 1 achieved. Thereby, that the control after the pressurization of the Piston releases a connection to the leakage fluid space in the housing, the fluid ejected from the piston space into the leakage fluid space of the housing passed, from which the pressure fluid via the leakage line from the housing to Tank discharged becomes. This allows a separate return line between the cylinder cover and tank are eliminated, since the pressure fluid after a working stroke Piston directed directly into the leakage fluid chamber of the housing and from there via the leakage line discharged to the tank becomes. The leakage fluid space of the housing has a dampening effect on the pulsating draining Fluid flow that is subject to decompression, causing a low-vibration and therefore low-noise Operation of the radial piston motor is achieved.

Das Abführen des aus dem Kolbenraum ausgestoßenen Fluids in den Leckraum des Gehäuses kann auch bei einer anderen Bauform des Radialkolbenmotors vorgesehen sein, bei der das Steuerelement in anderer Weise ausgebildet ist. Wesentlich ist hierbei, dass durch das Steuerelement nach dem Arbeitshub des Kolbens das Fluid aus dem Kolbenraum in den Leckraum des Gehäuses geleitet wird und die übliche Rücklaufleitung zwischen Gehäuse und Fluidtank entfällt.The removal of the from the piston chamber expelled Fluids can leak into the housing also provided for another design of the radial piston motor be in which the control element is designed in a different way. It is essential here that the control element after the working stroke of the piston, the fluid is directed from the piston chamber into the leakage chamber of the housing will and the usual Return line between housing and no fluid tank.
