Title
(EN) ELECTROMAGNETIC VALVE DRIVE DEVICE
(FR) DISPOSITIF D'ACTIONNEMENT D'ÉLECTROVANNE
(JA) 電磁弁駆動装置
Abstract
(EN)
Provided is an electromagnetic valve drive device whereby the hysteresis value of a drive electric current for driving an electromagnetic valve can be controlled with good precision. The electromagnetic valve drive device pertaining to the present invention controls the set value of hysteresis and the time width of hysteresis on the basis of the difference between the extreme value of the hysteresis in a peak hold period of the drive electric current and the set value thereof.

L'invention concerne un dispositif d'actionnement d'électrovanne, grâce auquel dispositif la valeur d'hystérésis d'un courant électrique d'actionnement pour actionner une électrovanne peut être commandée avec une bonne précision. Le dispositif d'actionnement d'électrovanne selon la présente invention commande la valeur de consigne d'hystérésis et la fenêtre de temps d'hystérésis sur la base de la différence entre la valeur extrême de l'hystérésis dans une période de maintien de pic du courant électrique d'actionnement et la valeur de consigne de celle-ci.
