A hydraulic circuit for controlling a consumer of a mobile work tool, wherein the pressure in supply and outlet lines towards the consumer is limited by means of pilot-controlled pressure control valves. The pilot control stage of these pressure control valves may be adjusted in accordance with a pilot control pressure corresponding to the load of the work tool.
L'invention concerne un circuit hydraulique pour commander un consommateur (2) d'un outil de travail mobile (8), la pression dans les canalisations d'amenée et d'évacuation (14, 16) raccordées au consommateur étant limitée par l'intermédiaire de soupapes de limitation de pression (4, 4') à commande de pilotage. L'étage de pilotage (28) de ces soupapes de limitation de pression se règle en fonction d'une pression de pilotage correspondant à la charge de l'outil de travail.
