筒体活塞
摘要：
本发明涉及一种筒体活塞。具体而言，本发明涉及一种用于筒体的筒体活塞，该筒体用于将填充材料储存在筒体的储存腔室中，该活塞包括活塞主体，该活塞主体具有传送侧以及与传送侧相对设置的驱动侧，并且包括活塞套，其中，活塞套围绕活塞轴线布置，并且活塞主体在外围侧被活塞套包围。活塞套具有密封元件，以用于在活塞套的密封元件以及筒体的储存腔室的内壁之间形成流体密封连接，从而使密封元件在所安装状态下在传送侧与驱动侧之间形成流体密封连接。活塞主体包括第一通风元件和第二通风元件，传送侧和驱动侧可通过第一通风元件和第二通风元件由相应的开孔彼此连接，并且活塞主体具有通风切口，通风切口布置在传送侧上。
摘要（英）：

A piston for a cartridge for storing a filler material in a storage chamber of the cartridge includes a piston body which has a conveying side as well as a drive side disposed opposite the conveying side and includes a piston jacket, wherein the piston jacket is arranged around a piston axis and the piston body is surrounded by the piston jacket at the peripheral side. The piston jacket has a sealing element for forming a fluid-tight connection between the sealing element of the piston jacket and an inner wall of the storage chamber of the cartridge so that the sealing element forms a fluid-tight connection between the conveying side and the drive side in the installed state. The piston body contains a first and a second venting element by which the conveying side and the drive side can be connected to one another by a respective bore and the piston body has a venting slit which is arranged on the conveying side.
