Abstract: A plate is adapted for use in a microvalve and includes a displaceable member configured 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. The displaceable member includes an elongated arm portion, a plurality of actuator ribs connected through a central spine to the elongated arm portion, and a hinge portion. The actuator ribs have a first portion and a second portion, the first portion having a first end and a second end, the second end of the first portion connected to the central spine, the second portion having a first end and a second end, the second end of the second portion connected to the central spine. A channel is formed in the plate. A plurality of elongated openings are formed in the plate and define the actuator ribs, each elongated opening having longitudinally extending side edges. One of the elongated openings separates each rib in the second portion of ribs from an adjacent rib or the plate. The channel and a longitudinally extending side edge of one of the elongated openings separate the second portion of the actuator ribs from the plate and define an electrical isolation region.

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: An improved aerosol dispensing apparatus includes an aerosol container, a discharge piece movably mounted to the aerosol container, a flow control valve mounted within the discharge piece, a battery, and an electronically controlled metering valve electronically connected to the battery and in fluid communication with the flow control valve. The flow control valve is movable between an open position wherein a volume of an aerosol formulation is directed from the aerosol container through the flow control valve to the metering valve, and a closed position, wherein the metering valve is configured to precisely control a flow of the aerosol formulation outward of the discharge piece. A solenoid is electronically connected to the battery and is movable between an actuated position wherein the solenoid urges the flow control valve into the open position, and an un-actuated position wherein the flow control valve remains in the closed position.

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.
