    摘要： The radial turbo-blower comprises a stator (35) that is housed in a stator housing (10) and a rotor (13) that rotates within a pump housing (11). The rotor (13) comprises a cavity (23) with a bearing arrangement (26) that is received by a protruding bearing pin (25). A pump chamber (12) is separated from a stator chamber (22) by a thin partition wall (21). Thereby, an atmospheric pressure is maintained in the stator chamber (22). The blower consists of few components and has a short structural length. It is substantially maintenance-free and the rotor area is protected from being contaminated by oil.

    摘要： A friction pump includes a generally cylindrical first housing part, a generally cylindrical second housing part projecting axially into the inner space of the first housing part; a bearing mounted in the second housing part coaxially therewith; and a pump rotor supported for rotation in the bearing. The pump rotor has a cylindrical shell surrounding the second housing part. The pump further has a drive motor mounted in the second housing part for driving the pump rotor; and a helical channel defined between the inner face of the first housing part and the outer face of the pump rotor for pumping gases upon rotation of the pump rotor. The second housing part, the bearing, the pump rotor and the drive motor form a single structural unit that can be axially removed from the first housing part after releasing a coupler between the two housing parts.
