<p>The invention relates to a cartridge piston (1) having an outer wall (2), an inner support body (6) and radial connection webs (7) between the outer wall (2) and the inner support body (6). In order to ensure a good sealing behaviour also with unilateral strain or asymmetric strain by a pressing plunger, a stiffening body (9) connected to the connection webs (7) is provided between the outer wall (2) and the inner support body (6), with the connection webs (7) having a gap (11) extending at least up to half the height of the cartridge piston (1) at the lower side of the cartridge piston (1) between the outer wall (2) and the stiffening body (9).</p> |
