Abstract: A support for a trolley, having a running surface that is formed on the support for the trolley, an upper chord, a lower chord and braces that connect said chords together, wherein the braces are designed to be flat, and each brace has a main surface that faces away from the support longitudinally between the upper chord and the lower chord. Two of the braces form a brace pair in each case and are arranged next to one another as viewed in the direction of the longitudinal axis of the support, preferably on the outside of opposite longitudinal sides of the support. To provide such a support, the flat braces are releasably secured to the upper chord and/or to the lower chord. The invention also relates to an overhead transport device having such a support and a trolley that can be moved along the support on the running surface.

Abstract: A round filter element of a filter for a urea-water solution has a filter bellows with a filter medium that continuously extends circumferentially, relative to a filter element axis, around an element interior. An end body is fastened to an end face of the filter bellows and provided with a connecting section for fastening the round filter element to a housing cover of a filter housing of the filter. The end body has a central opening communicating with the element interior. The central opening has a central insertion section for receiving a flexible separation section of a volume compensation device of the filter and has an outer flow-through section enabling flow of the urea-water solution out of the filtration volume or into the filtration volume. The filter has a volume compensation device with a flexible separation section that separates a compensation volume from the filtration volume of the filter.
