HYDRAULIC SYSTEM

Disclosed is a hydraulic system in which several consumers (5', 5''; 5''') are powered by a common pump (1). The pump (1) is controlled as a function of the difference between the pump pressure (Delta P) and the maximum load pressure. This pressure difference (Delta Pma...

More Information
Summary:Disclosed is a hydraulic system in which several consumers (5', 5''; 5''') are powered by a common pump (1). The pump (1) is controlled as a function of the difference between the pump pressure (Delta P) and the maximum load pressure. This pressure difference (Delta Pmax) is compared with a minimum pressure difference (Delta Pmin) and the signal resulting from this comparison process used in a control unit (21) to adjust the reference-value signals (S1, S2, S3) with which the individual valves (6'; 6''; 6''') are controlled. Dans un système hydraulique, plusieurs consommateurs (5'; 5'';5''') sont alimentés par une pompe commune à débit variable (1). La pompe à débit variable (1) est mise en fonction pour une pression située entre une pression de pompe (Delta P) et une pression de charge maximale. Cette différence de pression (Delta Pmax) est mise en relation avec une différence de pression minimale (Delta Pmin), et le signal de comparaison est utilisé dans un dispositif de commande (21) afin d'influer sur des signaux de valeur de consigne (S1, S2, S3) avec lesquels les différentes soupapes (6'; 6''; 6''') sont pilotées.
