Title:
【発明の名称】特にインジェクタのための液圧的な制御装置
Document Type and Number:
Japanese Patent JP2003512573
Kind Code:
A
Abstract:
The invention is based on a hydraulic control device (60), in particular for an injector (16) of a fuel injection system (10) in motor vehicles. Known control devices have a piezoelectric actuator, which controls a multi-position valve (75), embodied as an outward-opening valve with a valve member (74) guided in a valve bore (76).According to the invention, it is proposed that a booster (62) that reverses the deflection motion of the actuator (52) be disposed between the actuator (52) and the valve member (74), and that the multi-position valve (75) be embodied as an inward-opening 3/2-way valve. The valve member (74) of this valve, in operative connection with a valve seat (98) and a control edge (96), alternatingly opens or closes pressure fluid connections between pressure fluid conduits (86, 88, 92).
