Title (EN) CONNECTION STRUCTURE OF EGR VALVE AND EGR COOLER
(FR) STRUCTURE DE CONNEXION DE SOUPAPE RGE ET REFROIDISSEUR RGE
(JA) EGRバルブとEGRクーラの結合構造
Abstract:
(EN) An EGR valve (3) and an EGR cooler (4) are integrally connected. The EGR cooler (4) includes: a housing (11); a heat exchanging unit (12); a downstream-side flow path (11b) that is provided to the housing (11) at a location downstream of the heat exchanging unit (12); and an EGR gas outlet (11c) that guides an EGR gas from the downstream-side flow path (11b) to the outside. The heat exchanging unit (12) exchanges heat between cooling water and the EGR gas. The EGR valve (3) includes an EGR gas flow path (23a) and a flowrate control unit (24). The EGR valve (3) is directly connected to the downstream-side flow path (11b). The EGR valve (3) has the flow path (23a) and the flowrate control unit (24) housed in the downstream-side flow path (11b). The EGR gas that has flown from the heat exchanging unit (12) to the downstream-side flow path (11b) passes through the flow path (23a) and the flowrate control unit (24) of the EGR valve (3), and then flows outside through an EGR gas outlet (11d).
(FR) L'invention concerne une soupape RGE (3) et un refroidisseur RGE (4) qui sont raccordés d'un seul tenant. Le refroidisseur RGE (4) comprend : un boîtier (11) ; une unité d'échange de chaleur (12) ; un trajet d'écoulement côté aval (11b) disposé dans le boîtier (11) à un emplacement en aval de l'unité d'échange de chaleur (12) ; et une sortie de gaz RGE (11c) qui guide un gaz RGE du trajet d'écoulement côté aval (11b) vers l'extérieur. L'unité d'échange de chaleur (12) échange de la chaleur entre l'eau de refroidissement et le gaz RGE. La soupape RGE (3) comprend un trajet d'écoulement de gaz RGE (23a) et une unité de commande de débit (24). La soupape RGE (3) est directement raccordée au trajet d'écoulement côté aval (11b). La soupape RGE (3) comporte le trajet d'écoulement (23a) et l'unité de commande de débit (24) logée dans le trajet d'écoulement côté aval (11b). Le gaz RGE qui s'est écoulé de l'unité d'échange de chaleur (12) au trajet d'écoulement côté aval (11b) passe à travers le trajet d'écoulement (23a) et l'unité de commande de débit (24) de la soupape RGE (3), et s'écoule ensuite à l'extérieur par l'intermédiaire d'une sortie de gaz RGE (11d).
(JA) EGRバルブ(3)とEGRクーラ(4)が一体的に結合される。EGRクーラ(4)は、ハウジング(11)、熱交換部(12)、熱交換部(12)より下流にてハウジング(11)に設けられる下流側流路(11b)、下流側流路(11b)からEGRガスを外部へ導出するEGRガス出口(11c)を含む。熱交換部(12)は、冷却水とEGRガスとの間で熱交換が行われる。EGRバルブ(3)は、EGRガスの流路(23a)と流量制御部(24)を含む。EGRバルブ(3)が下流側流路(11b)に直接結合される。EGRバルブ(3)は、流路(23a)及び流量制御部(24)が下流側流路(11b)の中に収容される。熱交換部(12)から下流側流路(11b)へ流れたEGRガスは、EGRバルブ(3)の流路(23a)及び流量制御部(24)を通過してから、EGRガス出口(11d)を介して外部へ流出する。
