The invention relates to a wet rotor pump comprising an axial flux motor that includes a stator (110, 112, 114) and a rotor (122, 124). The stator is arranged in a dry zone while the rotor on an impeller (128) is arranged in a wet zone. The wet rotor pump further comprises an intake duct (134, 156) for a fluid (108) to be pumped by the impeller, and a bearing (154, 156) for the impeller. Said bearing is arranged at one end of the intake duct and supports the impeller in such a way that the impeller has an axial degree of freedom. The intake duct extends through the stator and the bearing in the axial direction. The bearing is a plain bearing which is used to radially support the impeller and axially support the impeller in one direction as an abutment for the magnetic force of attraction that the stator exerts on the impeller.

Abstract:
The invention relates to an exhaust gas turbocharger for an internal combustion engine (100) having a housing (2A) comprising an exhaust gas guide segment (3), an air guide segment (28), and a bearing segment (29), having a rotor assembly (2B) comprising a turbine wheel (5) having a plurality of blades (10), a compressor wheel (30), and a shaft (31) rotationally fixing the turbine wheel (5) to the compressor wheel (30), wherein the turbine wheel (5) is rotationally supported in the exhaust gas guide segment (3) and the compressor wheel (30) is rotationally supported in the air guide segment (28), and the shaft (31) is rotationally supported in the bearing segment (29), wherein the turbine wheel (5) can be acted on by exhaust gas from the internal combustion engine (100) and the compressor wheel (30) can be driven by means of the shaft (31) from the turbine wheel (5) for taking in and compressing air, and a sleeve-shaped sliding element (14) is positioned in the exhaust gas guide segment (3) for conditioning the exhaust gas acting on the turbine wheel (5). According to the invention, the sleeve-shaped sliding element (14) is designed for at most partially receiving an outer blade contour (12) of the turbine wheel (5). The simple variability in the outer wheel contour - wheel exit area, together with the conventional adjusting devices upstream of the turbine wheel, allows a fully variable turbine. The optimal reaction level can thereby be set for operating points of the turbine at lesser and greater injectivity. The invention is used both in commercial vehicle design and in passenger car design.
Abstract:
The invention relates to a method for controlling a ship propulsion system (1) comprising a surface propeller (5) in which the desired capacity is interpreted as the target rotational value (nSL), the rotational speed control deviation is calculated from the desired rotational value (nSL) and the actual rotational value (nIST) of the internal combustion engine (2) and an injection quantity (qV) for the rotational control of the internal combustion engine (2) is determined using the rotational speed control deviation on a rotational speed controller (14). According to said method, the trim position (POS) of the surface propeller (5) is controlled by means of an arrangement controller (8) in accordance with the capacity reserve (PRES) of the internal combustion engine (2) and the actual trim position (POS(IST) ) and the effective rotational speed (nEFF), said trim position being determined from the rotational speed control deviation.
