Abstract
A firing device has a housing () for an injector () with a trigger () whose action to eject a dose from its needle () is forwards against a resistance. The housing contains a spring () which acts on an axially movable locator () for the injector () that co-operates with its trigger (). The device is primed by compressing the spring (), the injector then being latched in a rearward position. Release of the catch () causes the spring () first to propel the injector () forwards, acting through the locator () and trigger (), until the needle () is projected, and then to overcome the resistance to the trigger () to actuate that and cause a dose to be ejected.
