Abstract
A two or three way microelectrovalve with twin sealing membrane is provided in which the mobile assembly playing the role of closure member driven by the mobile core of an electromagnet is essentially formed of two flexible membranes mounted on each side of a core which passes through a central well in the main body of the microelectrovalve, whose two opposite faces are countersunk so as to form cups. The outgoing pipes which open into a zone of the cups set aside from the central well 6 are sealingly closed by each membrane by a small excentric part of the surface thereof.
