摘要： A gas flow reversing element is disclosed that includes a main piece comprising an inflow region, a nozzle region and a mixing region, and further includes a branching piece. The inflow region connects a pressure connector to a closable outlet opening in the mixing region, the branching piece connecting the nozzle region to a line connector. With the outlet opening opened, gas flow flowing along a first flow path from the pressure connector through the nozzle to the outlet opening, generates a gas flow in the branching piece flowing along a second flow path from the line connector to the outlet opening. The reversing element further includes a bypass, closable by at least one closing element, connecting the pressure connector and the line connector so that a gas flow can flow along a third flow path via the inflow region, and bypass the nozzle via the bypass.
