Microvalve Having Improved Resistance to Contamination

机译:微型阀具有增强的抗污染能力

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.
