Abstract
L'invention concerne un dispositif dans lequel le fluide hydraulique s'écoule alternativement dans un sens puis dans l'autre en quantité relativement faible. Le dispositif est caractérisé par le fait qu'on interpose dans la conduite un organe mobile se déplaçant avec le fluide et séparant celui-ci en fluide amont et fluide aval, ledit organe obstruant la conduite 10 lorsque sa course alternative est plus importante que la normale. Application aux freins notamment.
