A micro-valve arrangement whose micro-valve has a housing containing two opposite housing layers, between which a valve chamber is delimited, wherein a valve member is located. A fluid duct extending in one housing layer opens into the valve chamber and is controlled by the valve member. By means of an electrically operated actuator it is possible for the position of the valve member to be predetermined. Furthermore a position detector is present, which on the basis of the measured capacitance of a capacitor renders it possible to find the position of the valve member. This capacitor comprises two capacitor faces which are provided opposite to each other in the direction of motion of the valve member and on one of the housing layers.

[ What is claimed is:] [1.] A micro-valve arrangement comprising a micro-valve which has a housing produced by a micro-structuring method, such housing having two mutually opposite housing layers, between which a valve chamber is defined, in which a diaphragm- or plate-like valve member is located,

[ What is claimed is:] [1.] A micro-valve arrangement comprising a micro-valve which has a housing produced by a micro-structuring method, such housing having two mutually opposite housing layers, between which a valve chamber is defined, in which a diaphragm- or plate-like valve member is located, at least one of the two housing layers having at least one fluid duct extending therein, such duct opening opposite to the valve member at a port, in controlling cooperation with the valve member, into the valve chamber, and an electrical actuator for presetting the relative position of the valve member in relation to the duct port, wherein the micro-valve comprises a position finding means for finding the position of the valve member on the basis of the measured capacitance of a capacitor, such capacitor comprising two capacitor faces which are opposite to each other in the direction of motion of the valve member and are respectively provided on the valve member and on one of the housing layers.
