Abstract: A microvalve includes a first plate having a surface defining an actuator cavity. A second plate has a surface that abuts the surface of the first plate and 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. An actuator is connected to the displaceable member and has only one or two pairs of actuator ribs.

Abstract: A method of attaching a MEMS die to a surface includes centering and rotationally aligning a solder perform on a solder surface of a body, centering and rotationally aligning a MEMS die on the solder preform, and heating the solder perform in a reflow process until the solder is molten and surface tension of the molten solder moves the MEMS die to a position where the surface tensions balance, and the MEMS die is centered on, and rotationally aligned with, the solder surface of the body.

Abstract: A system for controlling fluid pressure to a transmission system through a MEMS microvalve includes a transmission controller configured to receive a target command pressure, a current system command pressure input signal, and a transmission system operating temperature. A power determination module determines a temperature-related power factor from the target command pressure, the current system command pressure input signal, the transmission system operating temperature received in the controller, and a look-up table within the controller. A power signal module adjusts the current system command pressure input signal by the temperature-related power factor and applies the adjusted current system command pressure input signal to the MEMS microvalve via the controller.

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 spool assembly configured for use in a two-stage proportional control valve in a fluid system includes a substantially cylindrical sleeve having an axially extending sleeve bore extending from an open first end to an open second end. A spool includes a spool bore that extends from an open first axial end to a closed second axial end and is slidably mounted within the sleeve bore. The spool further includes a first circumferentially extending groove defining a fluid flow path, a second circumferentially extending groove formed near a first end thereof, a third circumferentially extending groove formed near the second axial end thereof, a circumferentially extending pressure groove formed therein between the second axial end and the third circumferentially extending groove, and first, second, and third transverse fluid passageways formed through a side wall of the spool.

Abstract: A hybrid spool valve includes a body having a longitudinal bore. The bore has a fluid inlet chamber in fluid communication with a fluid inlet port and a fluid outlet chamber in fluid communication with a fluid outlet port. A spool is slidably mounted in the bore and is movable between a fully open position, a fully closed position, and a plurality of partially open positions. A pilot microvalve is mounted within the bore and is configured to control the sliding movement of the spool by varying the flow of fluid therethrough. A seal is disposed in a groove formed in an outside surface of the spool such that when the spool is in the fully closed position the seal engages a wall of the bore, and when the spool is the fully open position or one of the partially open positions the seal does not engage the bore.
