A one way braking means comprising a first sealed chamber filled with a viscous fluid, a braking rotor being rotably supported within the chamber, a housing or the braking rotor, respectively, coacting with a pinion (54) which in turn cooperates with a tooth rod or a gear or the like, characterized in that the first housing (18a) is floatingly supported in a second chamber (16a) of a second housing (10a), the circumference of the first housing (18a) and a locking portion of the wall of the second chamber (16a) are formed such that a positive interengagement between first and second housing takes place if by a linear first force component the first housing and the locking portion are moved against each other and that a free running between first and second housing is effected when a second force component opposite to the first component effects between first and second housing. <IMAGE> |
