Abstract
The cartridge piston has an outer wall, an inner support body and radial connection webs between the outer wall and the inner support body. In order to ensure a good sealing behavior under unilateral strain or asymmetric strain by a pressing plunger, a stiffening body connected to the connection webs is provided between the outer wall and the inner support body. The connection webs have a gap that extends at least up to half the height of the cartridge piston at the lower side of the cartridge piston between the outer wall and the stiffening body.
