摘要： The invention relates to an exhaust gas turbocharger having a hydrodynamic plain bearing or a hydrodynamic plain bearing, comprising a rotor (10) and a counter-bearing part (50) assigned to the rotor (10), wherein a rotor bearing surface of the rotor (10) and a counterface of the counter-bearing part (50) face each other to form the hydrodynamic plain bearing in the form of a combined journal—thrust bearing, having a continuous hydrodynamically load bearing gap formed between the rotor bearing surface and the counterface, wherein the rotor bearing surface and/or the counterface, when cut longitudinally and through the axis of rotation (R) in sectional view, form(s) a bearing contour forming merging contour sections (17.1 to 17.3; 44.1 to 44.3; 53.1 to 53.3) to generate hydrodynamic load capacities in both the radial and the axial direction, wherein a contour section (17.3; 44.3; 53.3) in sectional view in a first bearing area forms a linear section that is part of a, in particular cylindrical or partially cylindrical, bearing section rotating at least sectionally about the axis of rotation (R), wherein a further contour section (17.1; 44.1; 53.1), in sectional view in a second bearing area, forms a further linear section, which is part of a further bearing area rotating at least sectionally about the axis of rotation (R), wherein this further linear section forms an angle with the axis of rotation (R), and wherein the first and the second bearing area merge via a transition section. According to the invention, a friction-optimized bearing system is to be created, which is easy to manufacture and ensures a reliable and effective bearing arrangement even under highly dynamic loads. According to the invention, this is achieved by the further linear section forming an angle in the range from >30° to

摘要： A housing includes a seal, a first portion for receiving a first axial portion of a rotor, and a second portion for receiving a second axial portion of the rotor. The first portion includes a first cooling system having a cooling channel through which cooling medium flows and a first cooling channel intake, and a first abutment face which surrounds the first cooling channel intake. The second portion includes a second cooling system having a cooling channel through which cooling medium flows and a second cooling channel intake, and a second abutment face which surrounds the second cooling channel intake. The housing portions are connected so that the abutment faces rest on each other and the cooling channel intakes form a transition surrounded by the abutment faces. The seal is arranged between the abutment faces and extends around the transition and is spaced apart from the cooling channel intakes.

摘要： A cartridge for use in a pulse energy enhanced turbine of a turbocharger. At least first and second fixed separating blades (12) are provided between a nozzle ring (6) and a disk (29), the separating blades (12) maintaining separation of exhaust gas flows through a guide grid between a divided volute and a turbine wheel (11). Exhaust pulsation energy from different cylinders or cylinder groups of an engine or engine bank are kept separated up to the turbine wheel, so that the turbine wheel reacts to individual pulses of exhaust gas flow from engine exhaust ports.

The assembly (23) includes a fan (25), a compressor (27), and an electric drive (31) and/or a turbine (29). The fan (25) has an impeller (255) which is designed to convey a hydrogen containing recycle stream (250) to a fuel cell unit (1). The compressor (27) has a compressor wheel (275) which is designed to compress an air stream (270) for a fuel cell unit. The compressor wheel (275) and the impeller (255) are coupled to one another in a rotationally fixed manner. The electric drive (31) and/or a turbine (29) is/are designed to drive the impeller (255) and the compressor wheel (275) simultaneously.

摘要： A rotor of a fluid machine includes a wheel with a plurality of blades. Furthermore, the rotor includes an inter-blade area defined circumferentially between a first blade and a second blade of the plurality of blades with respect to the axis of rotation. Moreover, the rotor includes a balancing mark on the wheel and within the inter-blade area. The balancing mark is elongate and has a first end and a second end. The first end and the second end are stepped axially into the inter-blade area. The balancing mark extends arcuately between the first end and the second end. The balancing mark has a depth that varies as the balancing mark extends arcuately between the first end and the second end. The balancing mark has a width that varies as the balancing mark extends arcuately between the first end and the second end.
