Abstract

La présente invention porte sur un actionneur utilisant une pression pneumatique et une pression hydraulique et, plus particulièrement, sur un actionneur utilisant une pression pneumatique et une pression hydraulique, qui ajoute une pression d'un fluide à une tige actionnée par une pression d'air pour produire une plus forte poussée, un disque qui se déplace librement dans le fluide étant utilisé pour stabiliser la surface libre du fluide, évitant ainsi que de l'air ne se mélange dans le fluide de travail, éliminant naturellement l'air du fluide de travail et réduisant à un minimum la quantité de fluide de travail qui fuit vers l'extérieur, de telle sorte que la pression qui est appliquée à la tige et à un piston peut être portée au maximum.
