Abstract: A method of maintaining a fluid flow rate in a heating, ventilating, air conditioning, and refrigeration (HVAC-R) system while maintaining superheat in the HVAC-R system at a desired level includes: continuously measuring an operating fluid temperature of the HVAC-R system, continuously calculating HVAC-R system superheat at a pre-determined rate, determining if the calculated HVAC-R system superheat is stable, measuring and recording the operating fluid pressure of the HVAC-R system each time the calculated HVAC-R system superheat is stable, recording an average operating fluid pressure each subsequent time the superheat is stable, calculating an output PWM according to the equation: Output PWM=(Flow Rate Component)+(Superheat Component), and reducing fluid flow through a metering valve in the HVAC-R system when an actual HVAC-R system PWM is greater than the calculated output HVAC-R system PWM by adjusting a PWM signal to a microvalve in the metering valve, and increasing fluid flow through the metering valve in the HVAC-R system when the actual HVAC-R system PWM is less than the calculated output HVAC-R system PWM by adjusting the PWM signal to the microvalve in the metering valve.

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.
