Definitions

  • the invention is more specifically characterized in that the inner surface of the rotating member is formed, at its outer edge, with slots leading to the spaces between the vanes and these slots are tapered with their narrower ends closest to the inner surface of the rotating member so that the fluent substance will be distributed evenly over the surfaces of the outer vanes.

Abstract

Une tête de distribution permet de projeter du mortier contre la paroi d'une canalisation (12) destinée à être revêtue. Un ensemble d'ailettes rotatives intérieures (56) projette le mortier contre une surface conique évasée vers l'extérieur (40) et le mortier avance le long de la surface (40) jusqu'aux ailettes extérieures (48) sur son bord extérieur d'où le mortier est projeté en un jet dense à haute vitesse contre la paroi de la conduite. Les ailettes intérieures sont fixées individuellement et de manière amovible à un collier (60) sur le bord intérieur de la surface conique évasée.
