    • An aerosol generator includes a flow passage having an inlet and an outlet, a heater arranged relative to the flow passage for heating the flow passage, a source of material to be volatilized in communication with the inlet of the flow passage, a valve to open and close communication between the source of material and the inlet of the flow passage, and a pressurization arrangement for causing material in the source of material to be introduced into the flow passage when the valve is in an open position. The aerosol generator further includes a source of power for operating the heater and the valve, and a control device for controlling supply of power from the source of power to the heater and the valve. A metering device in an inhaler includes a pressurized source of medicated fluid and a metering chamber configured to deliver a predetermined volume of fluid to a heated flow passage in the inhaler. The metering chamber can be part of a rotary valve having a bore and a displacement member moveable within the bore from a first position where the fluid is loaded into the bore to a second position where the predetermined volume is ejected out of the bore. Another metering chamber has an elastic portion of a delivery passage in fluid communication with the pressurized source of liquid and the elastic portion of the delivery passage is deformed to eject the predetermined volume.
    • 气雾发生器包括具有入口和出口的流动通道,相对于流道设置的加热流道的加热器,与流动通道的入口连通的待挥发的材料源,打开的阀和 材料源与流路入口之间的紧密连通,以及用于当阀处于打开位置时将材料源中的材料引入流路的加压装置。 气溶胶发生器还包括用于操作加热器和阀的动力源,以及用于控制从动力源到加热器和阀的动力供应的控制装置。 吸入器中的计量装置包括加压的药液源和配置成将预定体积的流体输送到吸入器中的加热流动通道的计量腔。 计量室可以是具有孔的旋转阀的一部分,以及位于孔内的位移元件,该位移元件从第一位置移动到第二位置,在第一位置,流体被加载到孔中到第二位置,其中预定的体积被排出孔。 另一个计量室具有与加压液体流体连通的输送通道的弹性部分,并且输送通道的弹性部分变形以排出预定体积。

    • This invention relates to a device for volumetric flow control of particulate and fiber-like materials, specifically tobacco. More particularly, this invention relates to an apparatus having a contractible chute or a tilting conveyor. The discharge end of the chute or conveyor travels across the top of a container space, building an even pile of tobacco. When the level of tobacco in the container space reaches a certain height, a device signals the chute or tilting conveyor and the discharge end of the chute or conveyor moves rearward. When the moving conveyor floor of the container space moves the pile of tobacco forward, one or two devices signal the chute or tilting convey or, and the discharge end of the chute or tilting conveyor moves forward. The effect of this rearward and forward movement of the chute or tilting conveyor is to maintain volumetric control over the tobacco contained within the container space.
    • 本发明涉及一种用于颗粒状和纤维状材料,特别是烟草的体积流量控制的装置。 更具体地说,本发明涉及一种具有收缩斜槽或倾斜输送机的装置。 滑槽或输送机的排放端穿过容器空间的顶部,构成一堆烟草。 当容器空间中的烟草水平达到一定高度时,一个装置发出信号给斜槽或倾斜输送机,而滑槽或输送机的排放端向后移动。 当容器空间的移动输送机底板向前移动一堆烟草时,一个或两个装置向斜槽或倾斜输送器发出信号,或者滑槽或倾斜输送机的排放端向前移动。 斜槽或倾斜输送机的向后和向前运动的效果是保持容纳在容器空间内的烟草的体积控制。
