Abstract
Dispositif automatique de commande pour transmission hydrostatique. Le tiroir du distributeur de réglage comporte une gorge d'étranglement formant deux arêtes. L'une coupe la communication avec le réservoir quand la pression de travail est faible, l'autre coupe cette communication lorsque la pression est élevée, et la gorge laisse passer le fluide quand la pression a une valeur intermédiaire. Application notamment aux transmissions hydrostatiques pour véhicules.
