Abstract
An animal vaccination gun for administering a vaccination to an animal has a movable needle assembly which is brought into engagement with a metering chamber having a spring-biased piston mounted therein during the injection of a medicament to an animal. During the injection, fluid is forced out of the metering chamber and through the needle assembly by the spring-biased piston. After the injection, fluid pressure forces the needle assembly out of engagement with the metering chamber and enables the metering chamber to be refilled.
