METHOD FOR DETERMINING AN OPENING POINT POSITION VALUE AND VALVE DEVICE

A method for determining an opening point position value of a valve device with a valve unit, in particular a piezo valve unit, in which the opening point position value describes the position of a valve member of the valve unit at which position the valve member changes from a closed state to an op...

Beschreibung
Zusammenfassung:	A method for determining an opening point position value of a valve device with a valve unit, in particular a piezo valve unit, in which the opening point position value describes the position of a valve member of the valve unit at which position the valve member changes from a closed state to an open state. The method including providing a drive variable signal course to drive the valve member with a drive variable so that the valve member is moved from the closed state to the open state and/or from the open state to the closed state, during the provision of the drive variable signal course, recording a position characteristic curve of the valve member as a function of the drive variable, on the basis of the recorded position characteristic curve, determining the opening point position value.
