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: 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 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 translation: 微型阀包括具有内表面的第一板，设置在内表面内的凹入区域，设置在凹陷区域内的常开流体端口和常闭流体端口。 第一密封结构围绕常开流体端口延伸，并且第二密封结构围绕常闭流体端口延伸。 第二板限定不可移动部分和可移动部分。 不可移动部分的表面邻接第一板的内表面，不可移动部分具有通过其形成的开口。 可动部分形成在开口内，具有轴线，并且限定了通过形成在开口中的回旋弹簧连接到不可移动部分的可移动部件。 所述可移动构件在所述开口内在第一位置之间滑动和轴向地可移动，其中所述可移位构件与所述第二密封结构协作以防止流体连通通过所述常闭流体端口和第二位置，其中所述可移位构件不与 所述第二密封结构的至少一部分，以防止流体通过常闭流体端口连通。

Abstract: A microvalve includes a displaceable member having an elongated arm portion, a plurality of actuator ribs connected through a central spine to the elongated arm portion, and a hinge portion. Each of the actuator ribs has a first portion and a second portion, the first portions each having an end connected to the central spine, the second portions each having an end connected to the central spine. A channel is formed in the plate. A plurality of elongated openings is 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.
