An injection device for automatically squeezing out a dosage of injection liquid from a container. The injection device including a housing defining a longitudinal central axis； a first component； a second component； wherein the first and second component move relative to one another when the liquid is squeezed out； a spring configured to at least partially release stored energy to squeeze out the dosage； a setting device to set a rate at which the liquid is squeezed out； the setting device influencing the energy required for moving the second component relative to the first； the first component, when squeezing out liquid, is guided in the housing so as to be movable in the direction of the axis and to be rotationally fixed； and, the second component, when squeezing out liquid, is mounted relative to the housing so as to be rotatable and rotationally fixed in the direction of the axis.
