Abstract

The piezoelectrically operated valve (1) has a housing (2) containing a flexural converter (5) with an edge that can adopt a fluid channel opening position and a closing position and that is supported on at least a part (29,30) of its edge in the housing. Each part of the edge, with which the flexural converter is supported in the housing, is movably guided within the housing.
