    • An inhaler comprising a reservoir of an inhalable composition. A housing contains the reservoir and has an outlet end and an opposite end. A composition flow path for the flow of the composition extends from the reservoir along the flow path and out of a composition outlet at the outlet end of the housing. A flexible diaphragm within the housing defines an air flow path from an air inlet to an air outlet at the outlet end of the housing, the diaphragm extending past the air flow inlet towards the opposite end separating the air flow path on one side of the diaphragm from the remainder of the housing on the opposite side of the diaphragm. A valve element is movable with the diaphragm and biased by a biasing force into a position in which it closes the composition flow path, wherein suction on the outlet end reduces the pressure in the air flow chamber thereby lifting the valve element against the biasing force to open the composition flow path; and wherein the biasing force is arranged to close the composition flow path once the suction ceases.
    • 一种吸入器,包括可吸入组合物的储存器(5)。 壳体(I)包含储存器并具有出口端和相对端。 用于组合物流动的组合物流动路径(13)从储存器沿着流动路径延伸并且在壳体的出口(II)端部处从组合物出口延伸。 壳体内的柔性隔膜(16)限定从壳体的出口端处的空气入口(25)到空气出口(9)的空气流动路径,隔膜延伸经过空气流动入口朝向相对端部, 在膜片一侧的空气流动路径与膜片另一侧的其余部分的空气流动路径。 阀元件(15)可与隔膜(16)一起移动。
