Abstract
A rotary piston engine comprises a housing (10), which forms an interior space (11), and at least two rotary pistons (20, 30), which are arranged in the interior space (11). Formed on the interior space (11) are an inlet opening (13) and an outlet opening (15) to guide a fluid through the interior space (11). The rotary pistons (20, 30) are thereby driven by fluid flowing through. Each rotary piston (20, 30) has on its outer circumference at least two sealing strips (21, 31). According to the invention each rotary piston (20, 30) comprises at least two cavities (27, 37), in each of which a tube (38B) or an elastic solid rod is arranged. The sealing strips (21, 31) project into the cavities and against the tube (38B) received therein or the elastic solid rod. Through the tube (38B) or the rod, the sealing strips (21, 31) are pushed radially outwards.
