A rotor with variable hydrodynamic resistance for a sta-tionary water bicycle comprises a central body (12) provided on its perimeter with a plurality of blades (13) of the marine type comprising an inlet edge (13'), an outlet edge (13") and a convex helical surface, as well as provided on opposite outer faces with axles (14) per pedals (15), where-in each blade (13), at the outlet edge (13"), is connected to the rotor (10) with elastic fixing means (20) adapted to allow the automatic orientation of the blade (13) as a function of the rotation speed imparted to the rotor (10) through the pedals (15), wherein the central body (12) houses means for adjusting the maximum possible opening (30) comprising a mechanical end stop element (31) movable for modifying the maximum possible open-ing of each blade (13), such means for adjusting the maximum possible opening (30) of the blades being able to be actuated by control means (40) connected at one end to the means for adjusting the maximum possible opening (30). A stationary water bicycle comprising the rotor with vari-able hydrodynamic resistance is also object of the invention.

L'invention porte sur un rotor à résistance hydrodynamique variable pour un pédalo fixe, lequel rotor comprend un corps central (12) comportant sur sa périphérie une pluralité de pales (13) du type marine comprenant un bord d'attaque (13'), un bord de fuite (13'') et une surface hélicoïdale convexe, et comportant également sur des faces extérieures opposées des axes (14) pour pédales (15), chaque pale (13), au bord de fuite (13''), étant reliée au rotor (10) par des moyens de fixation élastiques (20) adaptés de façon à permettre l'orientation automatique de la pale (13) en fonction de la vitesse de rotation communiquée au rotor (10) par l'intermédiaire des pédales (15), le corps central (12) renfermant un moyen de réglage de l'ouverture possible maximale (30), comprenant un élément mécanique mobile d'arrêt d'extrémité (31) destiné à modifier l'ouverture possible maximale de chaque pale (13), lequel moyen de réglage de l'ouverture possible maximale (30) des pales pouvant être actionnés par un moyen de commande (40) relié à une extrémité au moyen de réglage de l'ouverture possible maximale (30). L'invention porte également sur un pédalo fixe comprenant le rotor à résistance hydrodynamique variable.
