Turboradialgebläse

摘要

The invention relates to a radial turbo-blower that comprises a stator (35) that is housed in a stator housing (10) and a rotor (13) that rotates within a pump housing (11). Said rotor (13) comprises a cavity (13) with a bearing system (26) that is received by a protruding bearing pin (25). The pump chamber (12) is separated from the stator chamber (22) by a thin partition (21), thereby maintaining in the stator chamber (22) an atmospheric pressure. The blower consists of few components and has a short length. It is substantially maintenance-free and the rotor area is protected from being contaminated by oil.
