Abstract

a. Dispositif d'amortissement pour système hydraulique équipant des appareils de traitement du sol, en particulier des charrues; b. Il est caractérisé en ce que un tiroir à piston est raccordé, par une face du piston, à la conduite sous pression menant au cylindre de travail servant au relèvement du corps de la charrue et, par sa face opposée, à la conduite sous pression menant au systeme prévu contre les surcharges dont est équipé le corps de la charrue. c. L'invention trouve son application dans le domaine des dispositifs d'amortissement pour système hydraulique équipant des appareils de traitement du sol, en particulier des charrues.
