Abstract (en)
[origin: EP2428282A1] The piston i.e. ring piston (51), has a piston mantel including a sealing element for forming fluid-tight connection between the sealing element and an inner wall of a storing chamber of a cartridge. The sealing element forms fluid-tight connection between a delivery side (53) and a drive side of a piston body in assembling condition. The piston body includes two ventilation elements (60, 61) through which the conveying and drive sides are connected with each other through a bore hole. A conveying side of the piston body is formed with ventilation slots (71, 73).
