Abstract

Moteur hydraulique comprenant un bloc-cylindres (6) ayant au moins un premier groupe de cylindres radiaux (12A), un organe de réaction (4A) à rotation relative par rapport au bloc-cylindres (6) et un distributeur interne de fluide (16) ayant des conduits de distribution. Le moteur comprend un sélecteur de débrayage unique (34) solidaire du bloc-cylindres (6) vis-à-vis de la rotation autour de l'axe de rotation (10) et comportant un conduit de communication (40) pour chaque cylindre (12A) du premier groupe de cylindres, le sélecteur étant susceptible d'occuper une première position permettant le raccordement des conduits de cylindre (15A) avec les conduits de distribution, une deuxième position permettant le débrayage des pistons des cylindres du premier groupe par la mise en communication des conduits de cylindre (15A) de ces cylindres avec une enceinte de décharge (48), et une position transitoire intermédiaire entre les première et deuxième positions, dans laquelle ces conduits de cylindre (15A) sont reliés entre eux par une enceinte isolée.
