To provide a solenoid valve control device capable of improving work efficiency in characteristic acquisition of a solenoid valve.SOLUTION: A solenoid valve 927 is constituted so that a valve element 61 is acted with force of a direction crossing an axial direction which axial direction is defined to be a direction in parallel with a central axis of an inflow passage 62 when a fluid flows into a valve chamber 65 from an outflow passage 66, and in a case that the solenoid valve 927 is to be normally operated, a control portion executes correction processing comprising:generating pressure at an inflow passage 62 side and an outflow passage 66 side of the solenoid valve 927 so that the fluid flows from the inflow passage 62 to the outflow passage 66; and upon detecting a special state relating to movement of the valve element 61, generating pressure at the inflow passage 62 side and the outflow passage 66 side of the solenoid valve 927 so that the fluid flows from the outflow passage 66 to the inflow passage 62 at a prescribed timing, so as to open the solenoid valve 927.SELECTED DRAWING: Figure 2
【課題】電磁弁の特性取得において、作業効率の向上が可能な電磁弁制御装置を提供する。【解決手段】本発明において、電磁弁927は、流入路62の中心軸に平行な方向を軸方向とすると、流出路66から弁室65にフルードが流入したときに、弁体61に軸方向に交差する方向の力が作用するように構成され、制御部は、電磁弁927を通常に作動させる場合、流入路62から流出路66へフルードが流動するように電磁弁927の流入路62側及び流出路66側の圧力を生成させ、弁体61の移動に関する特殊状態を検出した場合、所定のタイミングで、流出路66から流入路62へフルードが流動するように電磁弁927の流入路62側及び流出路66側の圧力を生成させて電磁弁927を開弁させる是正処理を実行する。【選択図】図2
