INJECTION DEVICE
First Claim
1. An injection device for automatically squeezing out a dosage of injection liquid from a container thereof, the injection device comprising:
- said container configured to hold the injection liquid;
a housing defining a longitudinal central axis;
a first component;
a second component;
wherein said first component and said second component move relative to one another when the injection liquid is squeezed out;
an injection spring configured to store energy and to, when the injection liquid is squeezed out from said container, at least partially release said stored energy to cause the dosage of the injection liquid to be squeezed out from said container;
a setting device to set an injection rate at which the injection liquid is squeezed out from said container;
said setting device being configured to influence the energy required for moving said second component in relation to said first component;
said first component, when squeezing out injection liquid, is guided in said housing so as to be movable in the direction of said longitudinal central axis and so as to be rotationally fixed; and
,said second component, when squeezing out injection liquid, is mounted in relation to said housing so as to be rotatable and so as to be rotationally fixed in the direction of said longitudinal central axis.

Abstract
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.
