Abstract
A piston (11) to be used in displacing a liquid inside a cylindrical chamber, preferably in an injection cartridge of the dual-chamber type, has at least one of its end surfaces (12) shaped convex such that said end surface or surfaces (12) are essentially planar when the piston has been arranged inside the barrel of said cartridge. Preferably both pistons in the cartridge have such a shape, their planar surfaces facing each other.
