The invention relates to a device for pumping a liquid in a liquid line, in particular into a bottling system. The aim of the invention is to provide a device for pumping a liquid in a liquid line, and the liquid-guiding areas thereof can be cleaned and/or disinfected from the outside without disassembling the piston or carrying out other operations in the arrangement. According to the invention, a device for pumping a liquid in a liquid line (1) comprises a pump element (2) and two valves (3, 4) which are arranged in the liquid line upstream of and downstream from the pump element, said pump element (2) comprising a pump piston (6) operating in a cylinder (5). The claimed device is characterized in that said pump element (2) comprises a closed chamber (7) having a constant volume of a secondary liquid on which the pump piston (6) works. Also, the chamber (7) is connected to the fluid line (1) by means of an elastic liquid-permeable element (8), said element can be deformed under pressure exerted by the volume of the secondary liquid displaced by the pump piston (6).

The present invention relates to an apparatus for filling and closing containers. The problem of the present invention is to develop an apparatus for filling and closing containers such that the risk of the apparatus being contaminated by spilled contents is effectively prevented. This problem is solved by an apparatus for filling and closing containers which comprises a first process wheel (1) for filling a container and a second process wheel (2) for closing a filled container and also a transfer device (3) for transferring the filled containers from the first process wheel (1) to the second process wheel (2). The transfer device (3) has a linear transfer route (4).

The invention relates to a rotor of a device for forming and/or filling containers made from preforms. The object of the invention is to provide a rotor of a device of this type, which permits the transfer of the preforms or the filled containers to a subsequent processing station with reduced force. This is achieved by a rotor (100) of a device of this type having a rotational axis A and having processing stations rotating about the rotational axis for receiving preforms or containers, wherein the processing stations move on a closed path (1) about the rotational axis A, characterised in that the distance of the path (1) to the rotational axis A is different depending on the position on the path (1), and the radius of curvature of the path (1) is greater in at least one section (12) than the greatest distance of the path (1) from the rotational axis A.
