Title (EN) RELIEF VALVE DEVICE AND HIGH-PRESSURE PUMP USING SAME
(FR) DISPOSITIF DE SOUPAPE DE DÉCHARGE ET POMPE HAUTE PRESSION L'UTILISANT
(JA) リリーフ弁装置、及び、それを用いる高圧ポンプ
Abstract:
(EN) A relief valve (1) capable of reducing the pressure of fuel in a discharge passage (214) is provided with: a valve housing (30) having a through-hole (310); a valve member (40) which is provided so as to be capable of reciprocating relative to the valve housing (30), prevents fuel from flowing between the discharge passage (214) and a fuel chamber (211) when in contact with an inner wall (311) formed around the through-hole (310), and permits fuel to flow between the discharge passage (214) and the fuel chamber (211) when moved away from the inner wall (311); a spring (45) for pressing the valve member (40) so that the valve member (40) and the inner wall (311) will be in contact with each other; an adjusting pipe (50) provided on the opposite side of the valve member (40) from the inner wall (311) and capable of adjusting the pressing force of the spring (45); and a stopper (60) provided as a separate element from the adjusting pipe (50) and coming in contact with the valve member (40) to prevent the valve member (40) from moving in the valve opening direction.
(FR) Une soupape de décharge (1) capable de réduire la pression du carburant dans un passage d'évacuation (214) comporte : un boîtier de soupape (30) ayant un trou traversant (310) ; un élément de soupape (40) qui est disposé de manière à pouvoir effectuer un mouvement alternatif par rapport au boîtier de soupape (30), empêche le carburant de s'écouler entre le passage d'évacuation (214) et une chambre de carburant (211) lorsqu'il est en contact avec une paroi intérieure (311) formée autour du trou traversant (310), et permet au carburant de s'écouler entre le passage d'évacuation (214) et la chambre de carburant (211) lorsqu'il est éloigné de la paroi intérieure (311) ; un ressort (45) permettant de presser l'élément de soupape (40) de sorte que l'élément de soupape (40) et la paroi intérieure (311) sont en contact l'un avec l'autre ; un tube de réglage (50) disposé sur le côté opposé de l'élément de soupape (40) à partir de la paroi intérieure (311) et capable de régler la force de pression du ressort (45) ; et un arrêt (60) fourni sous la forme d'un élément séparé du tube de réglage (50) et entrant en contact avec l'élément de soupape (40) pour empêcher l'élément de soupape (40) de se déplacer dans la direction d'ouverture de soupape.
(JA) 吐出通路(214)の燃料の圧力を低減可能なリリーフ弁(1)は、通孔(310)を有する弁ハウジング(30)、弁ハウジング(30)に対して往復移動可能に設けられ通孔(310)の周囲に形成される内壁(311)に当接すると吐出通路(214)と燃料室(211)との間の燃料の流れを規制し内壁(311)から離間すると吐出通路(214)と燃料室(211)との間の燃料の流れを許容する弁部材(40)、弁部材(40)と内壁(311)とが当接するよう弁部材(40)を付勢するスプリング(45)、弁部材(40)の内壁(311)とは反対側に設けられスプリング(45)の付勢力を調整可能なアジャスティングパイプ(50)、及び、アジャスティングパイプ(50)と別体に設けられ弁部材(40)に当接し弁部材(40)の開弁方向への移動を規制するストッパ(60)を備える。
