    • An inhaler comprising a breath operated valve with a valve element biased closed by a spring (22) and a diaphragm (11) arranged to deform when suction is applied to an outlet end (2) generating low pressure above the diaphragm (11) to lift the valve element (9) against the biasing force of the spring (22) allowing composition to flow out of the inhaler. The spring (22) is a strip of resilient material forming a U-shape with a first arm (23) extending from a position adjacent to the valve element along the diaphragm (11) in a direction away from the outlet end so as to support the diaphragm to an apex (24) where it extends away from the diaphragm into a second arm (25) extending back towards the outlet end (2), the second arm (25) engaging with the housing (1) to generate a biasing force to urge the valve element closed (9).
    • 一种吸入器,其包括具有被弹簧(22)关闭的阀元件的呼吸操作阀和设置成当向所述隔膜(11)上方产生低压的抽吸施加抽吸时变形的隔膜(11)以提升 克服弹簧(22)的偏压力的阀元件(9)允许组合物从吸入器流出。 弹簧(22)是形成U形的弹性材料条,其中第一臂(23)沿远离出口端的方向沿着隔膜(11)从邻近阀元件的位置延伸以支撑 所述隔膜到达顶点(24),其中其从所述隔膜延伸到朝向所述出口端(2)延伸的第二臂(25)中,所述第二臂(25)与所述壳体(1)接合以产生偏置力 以推动阀元件关闭(9)。
