摘要：
An exemplary embodiment of injector includes a trigger mechanism, an energy source, and a user-operable firing-initiation member. The trigger member can include a trigger member having a retainer portion, and a ram assembly having a ram configured to pressurize a medicament container for expelling a medicament therefrom and a trigger engagement member configured to engage the retainer portion of the trigger member in a pre-firing condition. The energy source can be associated with the ram for powering the ram to expel the medicament, and the user-operable firing-initiation member can be operable for causing an axial rotation between the trigger engagement member and the retainer portion from the pre-firing condition to a firing condition in which the trigger engagement member is released from the retainer portion to allow the energy source to fire the ram.
