Abstract: In an apparatus for treating containers with a medium, the containers are transported cyclically in groups. A linear holding device has a plurality of container holders for holding the containers in a suspended state. A treatment device has a plurality of outlet heads that are connected to a supply line for the medium via respective branch lines. The outlet heads are moved together as a group in the vertical direction. Each outlet head has an outlet line for discharging the medium into the containers. For the purpose of treating the container, the outlet line is introduced into the container, which is held in a suspended state in the container mount. Each outlet head is assigned a controllable restraining mechanism. A controller communicates with the restraining mechanism to control a restraining element to hold back the outlet line of a respective outlet head in a restraining position as required.

Abstract: A gas spring has a closed cylinder, the interior of which is divided into a first working space and a second working space by a piston, which is free to slide back and forth in the cylinder. The piston has a piston rod, which extends through the second working space and out from the cylinder through a seal. The first working space and the second working space are filled with pressurized gas. A compensating space, which is filled with a compensating medium, is also provided. The volume of this compensating medium changes with the temperature, and this change in volume brings about a corresponding change in the volume of the first working space. The compensating medium is an incompressible medium which expands in volume as the temperature drops, this expansion leading to a decrease in the volume of the first working space.
