Abstract
A displacement machine has at least two adjacent working chambers which are defined by: a) a common first wall section made of an elastic material; b) a common second wall section; and c) a movable element which is movable with respect to the first wall section, which movable element has a press-on section that presses the first wall section against the second wall section to form a common sealing region between the two adjacent working chambers, which common sealing region moves with the movement of the press-on section. At least one of the first and second wall sections is provided with a non-smooth profile on the inner side of the working chambers.
