Abstract
An injection device has a housing and a metering member held rotatably in the housing and fixed in the direction of a longitudinal central axis. The metering member via a threaded connection is connected to a sleeve held rotationally fixed in relation to the housing and displaceable in the direction of the axis. When setting a dosage, the metering member rotates relative to the housing, and the sleeve moves distally. When dispensing a set dosage, the sleeve moves in the proximal direction, and the metering member by virtue of the threaded connection rotates in the opposite direction. To enable an automatic injection, the device has a spring supported in relation to the injection sleeve via a first end and in relation to the housing via a second end; the spring, when squeezing out liquid, moves the sleeve proximally and on account thereof causes the set dosage to be dispensed.
