Abstract: The electronically switchable MEMS valve includes a housing formed from soft magnetic material and defining a fluid flow path therethrough. A magnetic field generating member is mounted within the housing and connected to a source of electrical power. A MEMS valve portion is mounted within the magnetic field generating member, has a valve closing member movably mounted therein, and defines a portion of the fluid flow path therethrough. The valve closing element is movable between a closed position wherein the fluid flow path is blocked, and an open position wherein the fluid flow path is not blocked. When an electric current is removed from the magnetic field generating member, the valve closing element is configured to move to and remain in the one of the closed position and the open position to which the valve closing element is the closest when the electric current is removed.

Abstract: A microvalve includes a first plate having a surface, a recessed region provided within the surface, a fluid port provided within the recessed region, and a sealing structure extending about the fluid port. A second plate defines a non-movable portion and a movable portion, a surface of the non-movable portion abutting the surface of the first plate, the non-movable portion having first and second openings formed therethrough. The movable portion is formed within the first opening and has an axis, the movable portion defining a displaceable member connected to the non-movable portion by a convoluted spring formed in a second opening. The displaceable member is slidingly and axially movable within the first opening between a closed position, wherein the displaceable member cooperates with the sealing structure to prevent fluid communication through the fluid port, and an opened position, wherein the displaceable member does not cooperate with at least a portion of the sealing structure to prevent fluid communication through the fluid port.

Abstract: A microvalve includes a first plate having a surface, a recessed region provided within the surface, a fluid port provided within the recessed region, and a sealing structure extending about the fluid port. A second plate defines a non-movable portion and a movable portion formed within the first opening and having an axis. A surface of the non-movable portion abuts the surface of the first plate, the non-movable portion having first and second openings formed therethrough. The first opening has a notch formed in each of two longitudinally extending side walls thereof. The movable portion defines a displaceable member connected to the non-movable portion by a convoluted spring formed in a second opening. The displaceable member has a tab extending outwardly from each of two longitudinally extending side walls thereof, each tab positioned within one of the notches. The displaceable member is slidingly and axially movable within the first opening between a closed position, wherein the displaceable member cooperates with the sealing structure to prevent fluid communication through the fluid port, and an opened position, wherein the displaceable member does not cooperate with at least a portion of the sealing structure to prevent fluid communication through the fluid port. The notches define stop surfaces that limit travel of the displaceable member between the closed position and the open position.
