Abstract

Afin d'obtenir un rendement élevé continu d'une turbine dans toute la gamme du réglage de débits, en l'absence quasi totale de dissipation supplémentaire de l'énergie du gaz grâce à la modification sans à-coups de la surface de passage de la partie d'accélération d'une volute, le procédé de l'invention de réglage d'une turbine centripète munie d'un appareil de direction sans ailettes prévoit la modification de la surface de l'orifice d'écoulement grâce à un mouvement curviligne en va-et-vient d'un élément profilé, dans le sens du courant ou à contre-courant par rapport au gaz injecté dans la volute. La forme géométrique, la position et la surface de la coupe de passage de la partie d'accélération de la volute sont déterminées par le mouvement en va-et-vient de l'élément profilé.
