Publication number: 20230313815Abstract: The invention relates to a stabilizer channel (10), in particular of a radial compressor or diagonal compressor, having an annular stabilizer chamber (12) which encloses a main flow channel (13) in the intake region of a compressor wheel (21) and is delimited from the main flow channel (13) by an annular bridge (14). The annular stabilizer channel (12) is connected to the main flow channel (13) via a downstream flow inlet (15) and an upstream flow outlet (16). At least one separating element (T) is arranged in at least one of the flow inlet (15) and the flow outlet (16), with the result that an inflow into the annular stabilizer chamber (12) and/or an outflow out of the annular stabilizer chamber (12) are/is split transversely with respect to the main flow direction (1) of the main flow channel (13). Furthermore, at least one flow guiding element (17) is arranged in at least one of the flow inlet (15) and the flow outlet (16).Type: ApplicationFiled: May 10, 2021Publication date: October 5, 2023Inventors: Daniel Bernhard RUSCH, Gerd MUNDINGER

Publication number: 20230175522Abstract: The invention relates to a stabilizer of a compressor, in particular of a radial compressor or diagonal compressor. The stabilizer comprises a first annular stabilizer chamber which encloses a main flow channel in the intake region of a compressor wheel. The stabilizer further comprises a second annular stabilizer chamber which encloses the first annular stabilizer chamber. The invention further relates to a compressor, in particular a radial compressor or diagonal compressor, comprising the stabilizer according to the invention, and to a turbomachine, in particular a turbocharger, comprising the compressor.Type: ApplicationFiled: May 18, 2021Publication date: June 8, 2023Inventors: Daniel RUSCH, Gerd MUNDINGER

Patent number: 10473114Abstract: The present invention relates to a compressor assembly for a turbocharger. The compressor assembly may comprise a spiral housing with a flow channel which is designed to convey a fluid which can be sucked up from outside the compressor assembly, a compressor outlet flange which is fluidically connected to the spiral housing via the flow channel, and an injection device designed to introduce a fluid from outside the compressor assembly into the flow channel, wherein the injection device is arranged outside the flow channel of the spiral housing.Type: GrantFiled: April 27, 2016Date of Patent: November 12, 2019Assignee: ABB Turbo Systems AGInventors: Daniel Rusch, Gerd Mundinger

Patent number: 9169738Abstract: A shaft seal of the rotating wheel shaft of a turbomachine includes a rotating wheel-side seal and a bearing-side seal between the bearing housing and the shaft. An oil outlet chamber is arranged between the rotating wheel-side seal and the bearing-side seal. The oil outlet chamber is delimited by a third seal between the bearing housing and the shaft, and a gas discharge chamber is arranged between the third seal and the rotating wheel-side seal. The construction is actively cooled by means of at least one splash oil bore in the region of the oil drain channel, as a result of which coking of the shaft seal can be prevented. The third seal separates the oil issuing from the oil outlet chamber from the gas issuing from the gas discharge chamber.Type: GrantFiled: April 7, 2011Date of Patent: October 27, 2015Assignee: ABB TURBO SYSTEMS AGInventors: Joel Schlienger, Matthias Kies, Patrick Aberle, Gerd Mundinger

Patent number: 8398363Abstract: A device for sealing a bearing housing, which holds lubricating oil, from which a rotor supported inside the housing of an exhaust gas turbocharger is guided into a compressor housing, loadable by a mass flow of a charger. The device includes a fixed partition with a wall extension, a sealing disk fastened on a shaft of the rotor, a separating gap arranged between the sealing disk and the wall extension, and a drip device connected to an oil-collecting channel and directs lubricating oil collected in the oil-collecting channel into an oil drain by gravity. The drip device includes a drain-off surface for lubricating oil, which has a large axial distance from a rotating sealing disk which delimits the separating gap. Lubricating oil which can penetrate into the separating gap is guided into an oil drain of the bearing housing without interacting with the sealing disk.Type: GrantFiled: May 26, 2011Date of Patent: March 19, 2013Assignee: ABB Turbo Systems AGInventors: Gerd Mundinger, Joel Schlienger, Matthias Kies, Patrick Aberle
