Piezoventil

摘要

The device has a flexural converter unit in a valve housing with converters driven in opposite directions by applying a control voltage with parallel deflection planes and joined at the end to form a common bearing section pivotably mounted on the valve housing. A main converter for controlling a valve opening has a supporting converter that is forced against a supporting surface in its deflection path by applying the control voltage. The device has a flexural converter unit (8) in a valve housing containing at least two converters driven (12,13) in opposite directions by applying a control voltage with parallel deflection planes and joined at the end to form a common bearing section (14) pivotably mounted on the valve housing. One converter is a main converter for controlling a valve opening (24,25) and the other is a supporting converter that is forced against a supporting surface (44) in its deflection path by applying the control voltage.
