Title (EN) HYDRAULIC SYSTEM FOR ENGINE STARTER AND GENERATOR
(FR) SYSTÈME HYDRAULIQUE POUR DÉMARREUR DE MOTEUR ET GÉNÉRATEUR
Abstract:
(EN) A hydraulic engine system includes a first hydraulic pump-motor coupled to an engine and a second hydraulic pump-motor coupled to an electric machine. A hydraulic link fluidly connects the first and the second hydraulic pump-motors. During a cranking operation mode, the electric machine operates as a motor and transfers power via the second hydraulic pump-motor, the hydraulic link and the first hydraulic pump-motor to provide cranking torque to the engine. During a generator operation mode, the power generated by the engine is transferred via the first hydraulic pump-motor, the hydraulic link, and the second hydraulic pump-motor to the electric machine, operating as a generator, to generate electricity.
(FR) L'invention concerne un système de moteur hydraulique qui comprend un premier moteur-pompe hydraulique accouplé à un moteur et un second moteur-pompe hydraulique accouplé à une machine électrique. Une liaison hydraulique raccorde de façon fluidique les premier et second moteurs-pompe hydrauliques. Pendant un mode de fonctionnement de démarrage, la machine électrique fonctionne comme un moteur et transfère une puissance par l'intermédiaire du second moteur-pompe hydraulique, de la liaison hydraulique et du premier moteur-pompe hydraulique pour fournir un couple de démarrage au moteur. Pendant un mode de fonctionnement de générateur, la puissance générée par le moteur est transférée par l'intermédiaire du premier moteur-pompe hydraulique, de la liaison hydraulique et du second moteur-pompe hydraulique à la machine électrique, fonctionnant en tant que générateur, pour générer de l'électricité.
