Abstract
The invention provides a fluid switching microelectrovalve in which the mobile member playing the role of closure member for one or other of the pipes (18,19) is a single membrane (23) with oriented deformation applied by a rocker (24) against one or other of the pipes to be closed, the rocker (24) being moved from one to the other of its two balance positions corresponding to the two closure positions of the membrane by a spool (3) sliding in the valve body (1) under the action of the core of an electromagnet.
