    IPC: F25B41/06

    Abstract: A two-stage proportional control valve configured for use in a fluid system includes a valve body having a longitudinally extending valve body bore formed therethrough. A first stage microvalve is mounted within the valve body bore, and a second stage spool assembly is mounted within the valve body bore downstream of the microvalve. The second stage spool assembly includes a sleeve and a spool slidably mounted within the sleeve.

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

    Abstract: An electronically switchable, bi-stable two-port valve includes a sleeve, a first pole piece having air flow passages formed therethrough and a first wire-wound coil mounted therein and connected to a source of electrical power, a second pole piece having air flow passages formed therethrough and a second wire-wound coil mounted therein and connected to the source of electrical power, and a permanent magnet defining an armature and movably mounted between the first and second pole pieces. The first pole piece is mounted in a first end of the sleeve and the second pole piece is mounted in a second end of the sleeve.
