The invention provides a pump, compressor org like machine of the `sliding-vanetype comprising a sectional casing having a` working chamber of;

, Preferably, a two-part casing is employed which is constituted by a pair of fiat-bottom cup members provided at their meeting edges or rims with a spigot or tongue-and-groove joint. In
a pump or compressor for handling light liquids, air or other gases it is preferred to provide an even number of vane slots arranged in diametrical pairs so that the vane or vanes in one slot of the pair can be mechanically connected to the vane or vanes in the other slot of the pair. In machines for handling sludge or like dense liquids, this coupling together of diametrically The present invention also provides for a novel vane assembly, the rounded peripheral .portions of the vanes carrying curved packing members of half-ring form. These packing members are oatingly mounted on the vane peripheries and '5 spring-pressed into contact with the casing wall. Each vane may be equipped with one or more packing rings.
