Abstract

La présente invention a trait à une soupape à disque qui permet de couper le turbocompresseur d'un gros moteur destiné à un bateau. Jusqu'à présent, une plaque de fer était utilisée pour boucher ou ouvrir un tuyau d'évacuation relié au turbocompresseur d'un gros moteur. En d'autres termes, le procédé consistant à bloquer manuellement la plaque de fer sur le tuyau d'évacuation ou à les séparer manuellement a posé de nombreux problèmes. Cependant, la présente invention rompt avec le procédé existant et utilise la soupape à disque qui peut couper de manière très simple et très pratique le turbocompresseur du gros moteur.
