Title (EN) ELECTROMAGNETIC VALVE
(FR) SOUPAPE ÉLECTROMAGNÉTIQUE
(JA) 電磁弁
Abstract:
(EN) Provided is a low-cost electromagnetic valve that has excellent responsiveness to changes in the pressure of a fluid on a valve-main-body side. The electromagnetic valve V is provided with a valve main body 10, a valve body 50 disposed inside the valve main body 10 so as to be capable of reciprocating motion, an urging means that urges the valve body 50 in one direction, and a drive device 80 that is connected to the valve main body 10 and that exerts drive force on the valve body 50, wherein: a drive rod 84 of the drive device 80 has a guiding part 93 that faces an inner peripheral surface 83c of a fixed iron core 83 and guides axial movement, and a groove part 91 recessed farther radially inward than the guiding part 93; and the groove part 91 is formed continuously from a valve-main-body 10-side space through a movable-iron-core 85-side space S4.
(FR) L'invention concerne une soupape électromagnétique à faible coût présentant une excellente réactivité aux changements de pression d'un fluide du côté corps principal de soupape. La soupape électromagnétique (V) comprend un corps principal (10) de soupape, un corps de soupape (50) disposé à l'intérieur du corps principal (10) de soupape de manière à pouvoir effectuer un mouvement de va-et-vient, un moyen de sollicitation destiné à solliciter le corps de soupape (50) dans une direction, et un dispositif d'entraînement (80) relié au corps principal (10) de soupape et destiné à exercer une force d'entraînement sur le corps de soupape (50). Une tige d'entraînement (84) du dispositif d'entraînement (80) comprend une partie de guidage (93) faisant face à une surface périphérique interne (83c) d'un noyau de fer fixe (83) et destinée à guider un mouvement axial, et une partie rainure (91) évidée plus radialement vers l'intérieur que la partie de guidage (93) ; et la partie rainure (91) est formée en continu d'un espace côté corps principal (10) de soupape à un espace (S4) côté noyau de fer mobile (85).
(JA) バルブ本体側の流体の圧力の変化に対する応答性がよく、かつ低コストの電磁弁を提供する。 バルブ本体10と、バルブ本体10内に往復動自在に配置された弁体50と、弁体50を一方向に付勢する付勢手段と、バルブ本体10に接続されて弁体50に駆動力を及ぼす駆動装置80と、を備えた電磁弁Vであって、駆動装置80の駆動ロッド84は、固定鉄心83の内周面83cに対向し軸方向の移動を案内する案内部93と、案内部93よりも内径方向に凹む溝部91と、を有し、溝部91はバルブ本体10側の空間から可動鉄心85側の空間S4に亘り連続して形成されている。
