摘要： Die Erfindung betrifft einen Innenraumlüfter. Der Innenraumlüfter weist mindestens einen steuerbaren Ventilator und eine Steuereinheit auf. Der steuerbare Ventilator transportiert einen Volumenstrom eines einstellbaren Volumenstrom-Betrags an Luft aus einem Innenraum in einen Außenraum oder aus dem Außenraum in den Innenraum. Die Steuereinheit ist ausgebildet, in Abhängigkeit von einer Volumenstrom-Vorgabe eine Drehzahl des Ventilators zur Erzielung des Volumenstrom-Betrags entsprechend der Volumenstrom-Vorgabe zu bestimmen, Steuerinformationen zur Erzielung der bestimmten Drehzahl zu erzeugen und dem Ventilator zuzuführen. Weiter ist die Steuereinheit ausgebildet, einen Wert eines hydrostatischen Luftdrucks oder einen Wert, anhand dessen der hydrostatische Luftdruck bestimmbar ist, zu empfangen und die Drehzahl in zusätzlicher Abhängigkeit von diesem Wert zu bestimmen.

摘要： The invention concerns a rotary machine (1), comprising: a stator assembly (3) and a rotor assembly (4) centered on a central axis (X1); a magnetic bearing (5); and an auxiliary bearing (10) including a first ring (13) held in the stator assembly (3) and a second ring (14) delimiting a gap (G) radially to the central axis (X1) relative to the rotor (4). The second ring (14) is not rotating around the central axis (X1) in a primary operation mode and is dragged in rotation around the central axis (X1) in a secondary operation mode. The rotary machine (1) includes a monitoring system (50) for detecting a transition from the primary operation mode to the secondary operation mode. The monitoring system (50) comprises a target (60) formed on the second ring (14) and a sensor unit (70) fixed relative to the stator assembly (3). The invention also concerns a bearing and a method for manufacturing a rotary machine (1).

摘要： A surge avoidance control method for an exhaust turbine turbocharger avoids surging in an exhaust turbine turbocharger having a turbine that rotates with exhaust gas from an engine and a compressor rotationally driven by the turbine by controlling the opening angle of an operating device, capable of adjusting the operating point of the compressor, between fully open and fully closed. The method is provided with: a surge detection step of determining at predetermined time intervals whether the operating point of the compressor is positioned in a surge operating region; a surge avoidance opening angle calculation step of calculating a surge avoidance opening angle of the operating device which is necessary for moving the operating point of the compressor, determined to be positioned in the surge operating region in the surge detection step, outside the surge operating region; a correction opening angle calculation step of calculating, on the basis of a rate of movement of the operating point of the compressor determined to be positioned in the surge operating region in the surge detection step, a correction opening angle of the operating device; and an opening angle instruction value calculation step of calculating, on the basis of the surge avoidance opening angle and the correction opening angle, an opening angle instruction value for the operating device.
