Abstract
A miniaturized valve mechanism which has a valve containing a channel with at least one inlet and one outlet opening, as well as a device for closing the channel. In order to provide a valve arrangement which can be produced in the smallest possible size, the valve is controlled by a very small linear motor, the driver of which moves the device for closing and opening the channel by the application of a control voltage to a piezoelectric tube.
