本发明涉及一种用于设备的，特别是连续的，内容填充，具有封闭路径上的多个，特别是在圆形路径上，旋转，而至少一个填充区和至少一个分配区域通过活塞/气缸组件，每个包括一个气缸和 一个往复通过改变放置在填充材料可用填充体积往复运动活塞在汽缸中，所述可用到达活塞和气缸作为通气口，外围环形间隙，的壁之间的活塞的排气位置，通过该填充体积与真空源在 化合物，并且其中一个导向装置，用于将活塞的往复运动，这是有效的至少到达所述活塞的排气位置，以保持在横向方向上中心的活塞。

The invention relates to devices for, in particular continuous, filling of contents, with a plurality of on a closed path, in particular a circular path, orbiting, while at least one filling area and at least one delivery area passing piston / cylinder assemblies, each comprising a cylinder and one in the cylinder back while changing an available for the filling material filling volume and comprising reciprocating pistons, available from reaching a venting position of the piston between the piston and a wall of the cylinder as a ventilation opening, a circumferential annular gap through which the filling volume with a vacuum source compound, and wherein for the outward movement of the piston guide means is provided which is effective at least from reaching the venting position of the piston to keep the piston centered in the transverse direction.
