An injection device (20), in particular for injecting a reducing agent (30) into an exhaust system (22), has a compression space (16), the volume of which can be varied by moving a piston (1) which has a compression-space-side region (1b) facing the compression space (16) and an armature-side region (1c) facing away from the compression space (16), and an inlet valve (6, 8) which has at least one open position, in which said inlet valve provides a fluid connection between the compression space (16) and an external fluid source (24, 26), and at least one closed position in which said inlet valve severs the fluid connection between the compression space (16) and the external fluid source (24, 26), wherein the inlet valve (6, 8) is formed on the armature-side region (1c) of the piston (1). |
