Abstract

An injection cartridge (1) of the dual-chamber type has a bypass connection (12) between its two chambers (9, 10) which is arranged such that the interior wall of the cartridge is modified in a predetermined area in such a way that the movable wall (11) between the two chambers does not seal completely against the interior wall in said area. According to the invention, the modification of said wall is arranged as a plurality of lands and grooves (12) which have a direction that is inclined in relation to the longitudinal axis of the cartridge barrel.
