Abstract
Abstract A valve is disclosed in which a magnetic reed of flat springlike configuration closes an orifice in a plate by lying against a flat surface of the plate that has the orifice therein. A magnetic field applied to the reed causes the end of the reed to flex away from the flat surface with a peeling action to open the first mentioned orifice and to flex the reed to a second position in which it may close a second orifice.
