Title (EN) TURBO COMPRESSOR
(FR) TURBOCOMPRESSEUR
Abstract:
(EN) A turbo compressor, includes: an impeller housing having an impeller accommodation space, having an inlet formed at one side of the impeller accommodation space, and having an outlet formed at another side of the impeller accommodation space and communicated with the inlet; an impeller accommodated in the impeller accommodation space of the impeller housing, rotated together with a rotation shaft by being coupled to the rotation shaft, and configured to centrifugally-compress a fluid sucked through the inlet of the impeller housing, and to discharge the compressed fluid to outside of the impeller housing through the outlet; a back pressure space formed between a rear surface of the impeller and the impeller housing; a back pressure passage connected between the outlet of the impeller housing and the back pressure space; and a back pressure control valve installed between the back pressure passage and the back pressure space, and configured to selectively open and close a region therebetween.
(FR) La présente invention concerne un turbocompresseur comprenant : un carter de turbine ayant un espace de logement de turbine, comportant une entrée formée au niveau d'un côté de l'espace de logement de turbine, et une sortie formée au niveau d'un autre côté de l'espace de logement de turbine et communiquant avec l'entrée ; une turbine logée dans l'espace de logement de turbine du carter de turbine, entraînée en rotation conjointement avec un arbre de rotation du fait d'un accouplement à l'arbre de rotation, et conçue pour comprimer de manière centrifuge un fluide aspiré à travers l'entrée du carter de turbine, et pour évacuer le fluide comprimé vers l'extérieur du carter de turbine à travers la sortie ; un espace de contre-pression formé entre une surface arrière de la turbine et le carter de turbine ; un passage de contre-pression relié entre la sortie du carter de turbine et l'espace de contre-pression ; et une soupape de commande de contre-pression installée entre le passage de contre-pression et l'espace de contre-pression, et conçue pour ouvrir et fermer sélectivement une région entre ceux-ci.
