摘要： A microvalve includes a base plate including a surface, a recessed area provided within the surface, a first fluid port provided within the recessed area, and a first sealing structure extending about the first fluid port. The microvalve also includes a cover plate including a surface, a recessed area provided within the surface, a second fluid port provided within the recessed area, and a second sealing structure extending about the second fluid port. An intermediate plate is disposed between the base plate and the cover plate and includes a displaceable member that is movable between a closed position, wherein the displaceable member cooperates with the sealing structures to prevent fluid communication between the fluid ports, and an opened position, wherein the displaceable member does not cooperate with at least a portion of the sealing structures to prevent fluid communication between the fluid ports.

摘要： A microvalve includes a base plate having a surface defining an actuator cavity. A venting groove extends from a first cavity portion of the actuator cavity having a dead end region to a second cavity portion of the actuator cavity having a structure that can vent air from the microvalve. A cover plate includes a surface having an actuator cavity provided therein that includes a first cavity portion having a dead end region and a second cavity portion having a structure that can vent air from the microvalve. An intermediate plate includes a displaceable member that is disposed within the actuator cavity for movement between a closed position, wherein the displaceable member prevents fluid communication through the microvalve, and an opened position, wherein the displaceable member does not prevent fluid communication through the microvalve.
