Abstract

a. Moteur hydrostatique b. Il comprend des pistons de petits et de grands diamètres, un sous-ensemble de commutation, un sous-ensemble de distribution, l'ensemble de commutation comportant un tiroir monté dans un manchon fixe et ayant le rôle qu'en l'absence d'une pression de commande de commutation, il doit réaliser l'actionnement du piston de grand diamètre et en présence d'une pression de commande de commutation, il doit interrompre la circulation du liquide sous pression vers une surface inférieure du piston de grand diamètre en réalisant en même temps une communication entre ladite surface inférieure et un circuit de drainage. c. Construction des poids lourds.
