Abstract
An injector such as a hypodermic syringe and the like is improved in that an amount of injection each time thereof is mechanically determined by provisions of a stopper disconnectably attached to the barrel of the plunger and a plurality of convex/concave portions provided integrally on the outer surface of the plunger and cooperating with the stopper so that the stopper acts as a limiter for an advancing movement of the plunger in the cylinder of the injector to determine the amount of each injection of the injector.
