Abstract

La présente invention concerne une machine volumétrique dynamique centrifuge, qui comprend un corps hermétique doté d'orifices d'entrée et de sortie, ledit corps étant partiellement ou totalement rempli d'un liquide et contenant une roue à aubes montée rotative, laquelle se présente sous la forme d'un rotor doté de canaux radiaux. Les orifices d'entrée des canaux sont formés du côté de l'axe de la roue, et les orifices de sortie sont formés sur le pourtour du rotor. La machine selon l'invention est caractérisée en ce qu'elle possède des mécanismes d'arrêt, qui sont assemblés avec un jeu calibré à la roue à aubes sur le pourtour de cette dernière, et un distributeur, qui est placé dans le corps du côté de la partie centrale de la roue à aubes. Le distributeur et les mécanismes d'arrêt sont disposés de manière à pouvoir fermer périodiquement et simultanément les orifices d'entrée et de sortie d'au moins trois canaux de la roue à aubes lors de la rotation de cette dernière. Le distributeur et les mécanismes d'arrêt divisent le corps en au moins trois cavités de pompage reliées les unes aux autres par l'intermédiaire de conduits de raccordement, ainsi qu'à un conduit d'entrée et un conduit de sortie. Au moins un conduit de raccordement peut contenir un échangeur de chaleur et un séparateur se présentant par exemple sous la forme d'un récipient hermétique partiellement rempli de liquide et dans la partie supérieure duquel est formé un conduit de gaz de sortie.
