摘要：
A delay mechanism for staging the operation of an automatic injection apparatus (20) to ensure medication contents are properly delivered prior to the needled syringe (32) of the apparatus being retracted. In one form, the delay mechanism includes a shuttle (50), a follower (110), a locking member, a damping compound, and a driver and a driver biasing element (44). The shuttle is for a needled syringe of the apparatus and includes a first latching element. The follower includes a second latching element and a cammable surface, which second latching element is for cooperating with the first latching element to limit motion of the shuttle relative to the follower in a second direction opposite the first direction. The locking member is movable from a locking position to a release position by engagement with the syringe plunger during an injection, the locking member, when in the locking position, preventing rotation of the follower relative to the shuttle, the locking member, when in the release position, allowing rotation of the follower relative to the shuttle. The damping compound is between the follower and a supporting surface to dampen rotation of the follower relative to the shuttle. The driver is rotatably fixed relative to the shuttle and includes a camming surface. The shuttle allowing retracting of the syringe needle into the housing of the automatic injection apparatus after injection.Cette invention a trait à un mécanisme retard permettant dorganiser le fonctionnement dun appareil dinjection automatique afin de sassurer que la quantité de médicament est correctement administrée avant que laiguille à seringue de lappareil soit retirée. Sous une certaine forme, le mécanisme retard comprend une navette, un poussoir, un élément de verrouillage, un composé damortissement, un organe de commande et un élément modulant lorgane de commande. La navette est prévue pour une seringue à aiguille de lappareil et comprend un premier élément denclenchement. Le poussoir co
