Title (EN) FUEL INJECTION VALVE AND FUEL INJECTION DEVICE
(FR) SOUPAPE ET DISPOSITIF D'INJECTION DE CARBURANT
(JA) 燃料噴射弁及び燃料噴射装置
Abstract: front page image
(EN)A fuel injection valve has an injector body (4z) having formed in it high-pressure paths (6az, 6bz, 6cz) that allow high-pressure fuel to flow to a nozzle and receiving a piezo actuator (2z)(drive means) etc. for operating a needle (valve element) to open and close the nozzle; a fuel pressure sensor (50z) mounted on the body (4z) and detecting the pressure of the high-pressure fuel; a senor terminal (55z) for externally outputting the detected pressure value obtained from the fuel pressure sensor (50z); a drive terminal (56z) to which electric power for the piezo actuator (2z) is supplied; and a connector housing (70z) for holding the sensor terminal (55z) and the drive terminal (56z). The sensor terminal (55z), the drive terminal (56z), and the connector housing (70z) form a single connector.
(FR)L'invention concerne une soupape d'injection de carburant comprenant un corps d'injecteur (4z) doté de trajets haute pression (6az, 6bz, 6cz) qui permettent l'écoulement d'un carburant haute pression vers une buse et recevant un piézo actionneur (2z) (moyen d'entraînement), etc. pour ouvrir et fermer la buse; un capteur de pression de carburant (50z) monté sur le corps (4z) et détectant la pression du carburant haute pression; une borne de capteur (55z) pour émettre extérieurement une valeur de pression détectée provenant du capteur de pression de carburant (50z); une borne d'entraînement (56z) qui alimente le piézo actionneur (2z) en courant électrique; et un logement de connecteur (70z) contenant la borne de capteur (55z) et la borne d'entraînement (56z). La borne de capteur (55z), la borne d'entraînement (56z) et le logement de connecteur (70z) forment un connecteur unique.
(JA) 噴孔へ高圧燃料を流通させる高圧通路6az,6bz,6czを内部に形成するとともに、噴孔を開閉するようニードル(弁体)をさせるためのピエゾアクチュエータ2z(駆動手段)等を収容するインジェクタボディー4zと、ボディー4zに取り付けられて高圧燃料の圧力を検出する燃圧センサ50zと、燃圧センサ50zからの圧力検出値を外部に出力するセンサ用端子55zと、ピエゾアクチュエータ2zへの電力が供給される駆動用端子56zと、センサ用端子55z及び駆動用端子56zを保持するコネクタハウジング70zと、を備える。そして、センサ用端子55z、駆動用端子56z及びコネクタハウジング70zにより1つのコネクタを構成する。
