配量机构
摘要：
公开了一种用于输送多个单一经计量的剂量的配量机构。配量机构(6)包括剂量输送机构和止回机构(10)，所述止回机构被设置为防止剂量输送机构在全部经计量的剂量被输送之前朝向装填位置返回。所述止回机构包括：轨道，所述轨道限定致动路径和返回路径；和接合构件，所述接合构件被设置为容纳在所述轨道中。所述轨道和所述接合构件能够相对移动，使得接合构件被设置为在剂量输送机构的致动期间沿所述致动路径移动，并且在剂量输送机构的装填期间沿所述返回路径移动。至少一部分致动路径设置有带齿的轮廓，以防止接合构件在致动路径中的反向移动。
摘要（英）：

A dosing mechanism (6) for delivering a plurality of single metered doses includes a dose delivery mechanism; and a non-return mechanism (10), arranged to prevent the dose delivery mechanism from returning toward a primed position until a full metered dose has been delivered. The non-return mechanism includes a track defining an actuation path and a return path and an engagement member arranged to be received within the track. The track and engagement member are relatively moveable such that the engagement member is arranged to move along the actuation path during actuation of the dose delivery mechanism and along the return path during priming of the dose delivery mechanism. At least a portion of the actuation path is provided with a toothed profile to prevent reverse movement of the engagement member in the actuation path.
