<p>A system comprises a piston setting device and a cartridge comprising a piston and a cartridge chamber which can be filled by a filling mass. The cartridge chamber further comprises a closeable outlet opening for the discharge of the filling mass whereby the filling mass is storable in said cartridge chamber when the outlet opening is closed and the piston is inserted into the cartridge chamber. The piston comprises a first piston part which rests in sealed manner against the cartridge wall and a second piston part, which forms venting valve comprising a valve plug together with the first piston part, wherein said valve plug opens when a pressure is exerted on the side of the piston opposite to the filling mass by a piston setting device. Furthermore a piston setting device is provided, wherein the piston setting device comprises a housing, a conduit arranged in said housing, said conduit having a first end and a second end, said first end comprising an attachment element connectable to a vacuum source and said second end comprising a plunger, said plunger being connectable to a valve plug of the piston for opening said valve plug when said piston setting device is attached to said piston. Furthermore the invention relates to a piston setting device and a method for setting a piston in a cartridge by means of said piston setting device.</p> |
