Abstract
La présente invention concerne un groupe hydraulique comprenant un moteur électrique variable et une pompe à cylindrée variable hydrostatique pouvant être accouplée audit moteur électrique et dont l'angle de pivotement peut être réglé au moyen d'un dispositif de réglage hydromécanique. L'angle de pivotement peut être détecté par un capteur d'angle de pivotement et une pression de fonctionnement de la pompe à cylindrée variable peut être détectée par un capteur de pression. On peut réguler le régime du moteur électrique en fonction du capteur d'angle de pivotement et du capteur de pression.
