Abstract
A dose release firing system () for use in a medicinal inhaler (). The firing system can include a plunger (), and a stored energy device () configured to drive the plunger from a first position to a second position. The firing system can further include a guideway () and a projection () dimensioned to be received in the guideway, the guideway or the projection being fixedly coupled to the plunger. At least a portion of the guideway can have a helical shape, including a first portion with a first helix angle, and a second portion with a second helix angle, the second helix angle being less than the first helix angle. The projection and the guideway can be movable with respect to one another to cause the projection to be cammed along the guideway when the stored energy device drives the plunger to move from the first position to the second position.
