A rotor assembly (1) for a self propelling pool cleaner including a housing (2) having a water inlet orifice (7) and a water outlet orifice (9), a rotor (3) within the housing (2) including a plurality of vanes (4) defining a plurality of spaces (11, 12) between adjacent vanes (4) each vane (4) having pressure sealing means (10) forming a pressure seal between adjacent spacers (11, 12) when said pressure sealing means (10) is in contact with an internal wall of the housing (2) wherein a negative static water pressure applied at the outlet orifice (9) leads to a differential water pressure between two adjacent spaces (11, 12) causing rotation of the rotor (3).
L'invention concerne un ensemble rotor (1) pour un nettoyeur de piscine automoteur, lequel ensemble comprend un carter (2) présentant un orifice d'entrée d'eau (7) et un orifice de sortie d'eau (9), un rotor (3) situé à l'intérieur du carter (2) et présentant une pluralité d'aubes (4) qui définissent une pluralité d'espaces (11, 12) entre des aubes adjacentes (4), chaque aube (4) étant pourvue d'un moyen d'étanchéité (10) formant un joint d'étanchéité entre des espaces adjacents (11, 12) lorsque ce moyen d'étanchéité (10) est en contact avec une paroi interne du carter (2), une pression d'eau statique négative appliquée au niveau de l'orifice de sortie (9) induisant une pression d'eau différentielle entre deux espaces adjacents (11, 12), de façon à provoquer la rotation du rotor (3).
