【発明の名称】液体を制御するための弁
Document Type and Number:
Japanese Patent JP2000517027
Kind Code:
A
Abstract:
A valve for controlling fluids, which in order to be actuated, cooperates with a fluid-filled membrane actuator. A coupling chamber provided in the membrane actuator is sealed by two membranes as dividing walls. In order to compensate for fluid losses produced by pressure acting on the membrane actuator, a filling valve is provided, which is disposed in the region of one of the two membranes. A refilling of the membrane actuator during the closed phase of the control valve is assured by way of the filling valve. A filling of this kind can also compensate for length changes of the piezoelectric actuator, the valve, or the valve housing. The valve is designated for use in fuel injection devices for internal combustion engines of motor vehicles.
