An injection device has a housing in which a syringe can be received that has an injection needle, a receiving chamber, a piston and a piston ram, and a control arrangement for controlled actuation of the syringe during an application procedure that includes at least one puncture stroke, one injection stroke and one return stroke. The control arrangement has an actuation element for applying a drive force to a syringe holder which is movable relative to the housing and on which the receiving chamber can be secured, a ram holder which is movable relative to the housing and on which the piston ram can be secured, and a transmission mechanism by means of which the ram holder can be coupled to the actuation element. Provision is made that the transmission mechanism has a toothed gearing by means of which the ram holder can be driven, according to a relative movement of the actuation element with respect to the housing, and which for this purpose has teeth on the housing.
