Abstract

L'invention concerne un dispositif d'entraînement (10) comprenant des pompes céramiques (18a, 18b), le fluide de travail (100) circulant dans un passage d'écoulement (13a) étant pressurisé et dépressurisé de manière alternée par les pompes céramiques disposées sur les côtés gauche et droit d'un corps mobile (110), de sorte à déplacer ce corps mobile (110) dans le passage d'écoulement (13a). Le passage d'écoulement (13a) peut communiquer avec une chambre d'amortissement à pression interne (15a), un gaz compressible étant stocké dans des passages d'écoulement étroits (16a1 ET 16b1). Comme ces passages d'écoulement étroits provoquent une grande résistance d'écoulement lorsque la pression du fluide de travail (100) est augmentée ou réduite rapidement par les pompes céramiques, la pression à l'intérieur du passage d'écoulement n'est pas libérée vers la chambre d'amortissement à pression interne (15a), ce qui provoque le déplacement du corps mobile (110) dans le passage d'écoulement. A l'inverse, comme les passages d'écoulement étroits provoquent une faible résistance d'écoulement lorsque la pression du fluide de travail (100) augmente lentement à cause de la dilatation, le fluide de travail (100) est conduit dans la chambre d'amortissement à pression interne (15a) pour arrêter l'augmentation de la pression du fluide de travail (15a), ce qui permet d'éviter les dommages causés à une chambre de pompe ou à un joint, même lorsque le fluide de travail se dilate par voie thermique.
