Title
(EN) SHOVEL AND METHOD FOR DRIVING SHOVEL

Abstract
(EN)
This shovel has an assist hydraulic motor 40 for assisting the driving of an engine, and a regeneration valve 22G disposed between a hydraulic motor for turning and the assist hydraulic motor. When the hydraulic motor for turning decelerates and the pressure of hydraulic oil discharged from the hydraulic motor for turning reaches or exceeds a threshold value set on the basis of a relief pressure, a controller 30 opens the regeneration valve 22G and the hydraulic oil discharged from the hydraulic motor 21 for turning is supplied to the assist hydraulic motor 40.
(FR)
La pelle de l’invention possède : un moteur hydraulique auxiliaire (40) qui aide l’entraînement d’un moteur ; et une soupape de régénération (22G) disposée entre un moteur hydraulique pour rotation et le moteur hydraulique auxiliaire. Lorsque le moteur hydraulique pour rotation décélère, et que la pression d’une huile de fonctionnement libérée par le moteur hydraulique pour rotation est supérieure ou égale à une valeur seuil établie sur la base d’une pression de décharge, un organe de commande (30) ouvre la soupape de régénération (22G), et l’huile de fonctionnement libérée par le moteur hydraulique pour rotation (21) alimente le moteur hydraulique auxiliaire (40).
(JA)
 ショベルは、エンジンの駆動をアシストするアシスト油圧モータ40と、旋回用油圧モータとアシスト油圧モータとの間に配置された再生弁22Gとを有する。旋回用油圧モータが減速し、且つ、旋回用油圧モータから排出される作動油の圧力がリリーフ圧に基づいて設定される閾値以上となると、コントローラ30は再生弁22Gを開き、旋回用油圧モータ21から排出された作動油をアシスト油圧モータ40へ供給する。
