Beschreibung
Zusammenfassung:	The invention relates to a hydraulic load sensing system (12) for a working machine (1). The hydraulic system comprises a pump (13) for providing hydraulic fluid for driving an actuator (14), and a hydraulic accumulator (16). The hydraulic accumulator (16) is arranged to provide a hydraulic fluid pressure for generating an LS-signal for controlling the hydraulic fluid pressure delivered by the pump (13). L'invention concerne un système de détection de charge hydraulique (12) destiné à un engin de travail (1). Le système hydraulique comprend une pompe (13) destinée à fournir un fluide hydraulique pour commander un actionneur (14), ainsi qu'un accumulateur hydraulique (16). L'accumulateur hydraulique (16) est agencé de manière à fournir une pression de fluide hydraulique pour générer un signal de détection de charge pour commander la pression de fluide hydraulique fournie par la pompe (13).
