Rotary transmission leadthrough with: a shaft (3), which is rotatable about a longitudinal axis running in the longitudinal direction (L), with at least one longitudinal bore (26, 27, 28), which runs in the longitudinal direction (L) and in which a push rod (43, 44, 45) is respectively arranged such that it can be displaced back and forth in the longitudinal direction (L) in relation to the shaft (3) and with at least one aperture (22, 23) in a lateral shaft wall that extends in each case to an assigned longitudinal bore (26, 27, 28) and at least one push fork (12, 13, 14), which can be moved outside the shaft (3) in the longitudinal direction (L) and is respectively assigned to one of the push rods (43, 44, 45) and in each case an operative connection, running through the assigned aperture (22, 23) to the assigned longitudinal bore (26, 27, 28), between the assigned push fork (12, 13, 14) and the assigned push rod (43, 44, 45), which connection transmits a back and forth movement of the assigned push fork (12, 13, 14) in relation to the shaft (3) to the assigned push rod (43, 44, 45) and makes a rotational movement of the shaft (3) possible in relation to the assigned push fork (12, 13, 14).
L'invention concerne un passage tournant comprenant : un arbre (3) tournant autour d'un axe longitudinal s'étendant dans le sens longitudinal (L), présentant au moins un trou longitudinal (26, 27, 28) s'étendant dans le sens longitudinal (L), trou dans lequel est disposée respectivement une barre de poussée (43, 44, 45), coulissant selon un mouvement de va-et-vient dans le sens longitudinal (L) par rapport à l'arbre (3), et présentant au moins un passage (22, 23) dans une paroi d'arbre latérale qui s'étend respectivement jusqu'à un trou longitudinal (26, 27, 28) associé, et au moins un baladeur (12, 13, 14) associé respectivement à l'une des barres de poussée (43, 44, 45) et déplaçable à l'extérieur de l'arbre (3) dans le sens longitudinal (L), ainsi qu'une liaison active s'étendant respectivement à travers le passage (22, 23) associé jusqu'au trou longitudinal (26, 27, 28) associé, entre le baladeur (12, 13, 14) et la barre de poussée (43, 44, 45) associés, cette liaison active transmettant un mouvement de va-et-vient du baladeur (12, 12, 14) associé par rapport à l'arbre (3) à la barre de poussée (43, 44, 45) associée et permettant un mouvement rotatif de l'arbre (3) par rapport au baladeur (12, 13, 14) associé.
