Rotor device for a fuel heater with an air exhaust arranged coaxially in an air supply line

摘要

The rotor device (1) has a rotor hub (3) which is arranged coaxially to a rotor axis (A), and a rotor blade (4) with an adjustment direction (R1), an upstream side (S1) and a downstream side (S2), where the rotor blade is radially arranged around the rotor hub. A rotor rim (5) is provided for enclosing the former rotor blade in a radial manner. Another rotor blade (6) is arranged around the rotor rim in a radial manner. Another adjustment direction (R2) of the latter rotor blade is opposite to the former adjustment direction. Independent claims are included for the following: (1) a ventilation device with a cylindrical section; and (2) a fuel heater with a combustion chamber.
