(JA) ハイブリッド建設機械
Abstract: front page image
(EN) This hybrid construction machine is provided with: a first and a second main pump; a first and a second supply path; a first and a second circuit system; a hydraulic motor; a motor generator; an assist pump; a branched converging path connected to the assist pump; a first and a second logic valve; a switch valve disposed in another branching path and capable of switching between a state in which the assist pump is connected to the second supply path on the upstream side of the second logic valve, and a state in which the second main pump is connected to the hydraulic motor; and a check valve. The poppet diameter of the first logic valve is smaller than the poppet diameter of the second logic valve.
(FR) La présente invention concerne une machine de construction hybride comprenant : un premier et un second trajet d'alimentation ; un premier et un second système de circuit ; un moteur hydraulique ; un moteur-générateur ; une pompe d'assistance ; un trajet convergent ramifié relié à la pompe d'assistance ; un premier et un second clapet logique ; un clapet de commutation disposé dans un autre trajet de ramification et capable de commuter entre un état dans lequel la pompe d'assistance est relié au second trajet d'alimentation sur le côté amont de la seconde soupape logique, et un état dans lequel la seconde pompe principale est reliée au moteur hydraulique ; et un clapet anti-retour. Le diamètre de champignon du premier clapet logique est plus petit que le diamètre de champignon de la seconde soupape logique.
(JA)  ハイブリッド建設機械は、第1及び第2メインポンプと、第1及び第2供給通路と、第1及び第2回路系統と、油圧モータと、モータジェネレータと、アシストポンプと、アシストポンプに接続され分岐する合流通路と、第1及び第2ロジック弁と、他方の分岐通路に介装される、アシストポンプが第2ロジック弁の上流側の第2供給通路に接続する状態と、第2メインポンプが油圧モータに接続する状態と、を切り換え可能な切換弁と、チェック弁と、を備える。第1ロジック弁のポペット径は、第2ロジック弁のポペット径よりも小さい。
