Title (EN) ACTUATOR FOR A CLUTCH
(FR) ACTIONNEUR POUR UN EMBRAYAGE
(DE) AKTOR FÜR EINE KUPPLUNG
Abstract:
(EN) The invention relates to an actuator having a housing which has a housing inner chamber, a drive unit and a piston-cylinder unit and a pressure medium reservoir being located in the housing inner chamber. The piston-cylinder unit has a cylinder chamber with a piston which can be displaced in an axial direction therein. The cylinder chamber is part of the housing inner chamber and, with a first seal which interacts with the piston, forms a pressure chamber. The pressure medium reservoir forms a common volume with the cylinder chamber, a second seal being provided to seal the drive unit off from the pressure medium reservoir.
(FR) L'invention concerne un actionneur comprenant un carter présentant un compartiment intérieur dans lequel sont disposés une unité d'entraînement, une unité piston-cylindre et un réservoir à fluide sous pression, l'unité piston-cylindre présentant une chambre de cylindre dans laquelle un piston peut se déplacer le long d'une direction axiale, la chambre de cylindre faisant partie du compartiment intérieur de carter et formant une chambre de pression avec un premier élément d'étanchéité coopérant avec le piston, le réservoir à fluide sous pression formant un volume commun avec la chambre de cylindre. Un deuxième élément d'étanchéité sert à assurer l'étanchéité de l'unité d'entraînement par rapport au réservoir à fluide sous pression.
(DE) Die Erfindung betrifft einen Aktor mit einem Gehäuse, das einen Gehäuseinnenraum aufweist, wobei in dem Gehäuseinnenraum eine Antriebseinheit und eine Kolben-Zylindereinheit sowie ein Druckmittelreservoir angeordnet sind, wobei die Kolben-Zylindereinheit einen Zylinderraum mit einem darin entlang einer axialen Richtung verlagerbaren Kolben aufweist, wobei der Zylinderraum ein Teil des Gehäuseinnenraums ist und mit einer mit dem Kolben zusammenwirkenden ersten Dichtung einen Druckraum ausbildet, wobei das Druckmittelreservoir mit dem Zylinderraum ein gemeinsames Volumen bildet; wobei zur Abdichtung der Antriebseinheit gegenüber dem Druckmittelreservoir eine zweite Dichtung vorgesehen ist.
