Abstract

Es handelt sich um einen fluidbetätigten Drehantrieb, dessen Gehäuse (2) sich aus wenigstens drei aneinander gereihten Gehäusekörpern (6) zusammensetzt, wobei benachbarte Gehäusekörper jeweils eine Gehäusekammer (16a, 16b) begrenzen, in der ein Schwenkkolben (3a, 3b) aufgenommen ist. Dieser Schwenkkolben (3a, 3b) unterteilt die zugeordnete Gehäusekammer (16a, 16b) in zwei Arbeitsräume, wobei die für die Erzeugung gleichgerichteter Drehmomentanteile zuständigen Arbeitsräume über interne Fluidkanäle (47) des Gehäuses (2) miteinander verbunden sind. Die Verbindung von Arbeitsräumen benachbarter Gehäusekammern (16a, 16b) erfolgt hierbei mittels Fluidkanalabschnitten (47b), die den zwischen benachbarten Gehäusekammern (16a, 16b) angeordneten Zwischenkörper (16c) des Gehäuses (2) durchsetzen.

Figure imgaf001
It is a fluid-operated rotary drive whose housing (2) is composed of at least three lined housing bodies (6), wherein adjacent housing bodies each define a housing chamber (16a, 16b) in which a pivoting piston (3a, 3b) is received. This oscillating piston (3a, 3b) subdivides the associated housing chamber (16a, 16b) into two working spaces, wherein the working spaces responsible for generating rectified torque portions are interconnected via internal fluid channels (47) of the housing (2). The connection of working chambers of adjacent housing chambers (16a, 16b) takes place here by means of fluid channel sections (47b) which pass through the intermediate body (16c) of the housing (2) arranged between adjacent housing chambers (16a, 16b).
