Patent number: 11879389Abstract: An exhaust turbine includes a turbine wheel having a plurality of rotor blades, an exhaust outlet where the exhaust outlet is arranged downstream of the rotor blades and is delimited radial to the outside by an axial turbine diffusor. An exhaust mass flow can be output in an axial flow direction by the exhaust outlet duct and the axial turbine diffusor opens downstream, radially to the outside at a non-constant diffusor-opening angle, such that at a first diffusor-opening angle deviates from a second diffusor-opening angle by at least 1°. The exhaust turbine further includes a waste gate duct, the outlet region of which opens into the diffusor or directly downstream of the diffusor into the exhaust outlet duct. The waste gate duct is designed to generate a substantially axial flow direction of a waste gate mass flow at the outlet region of the waste gate duct.Type: GrantFiled: September 9, 2020Date of Patent: January 23, 2024Assignee: Turbo Systems Switzerland Ltd.Inventors: Christoph Mathey, Stephan Senn

Patent number: 11208919Abstract: The invention relates to an exhaust gas turbine, comprising a turbine rotor (12) having a plurality of turbine rotor blades (2) with a turbine rotor blade height H. The exhaust gas turbine further comprises a diffuser arrangement (20) having a transverse diffuser (1) and an exhaust gas collection chamber (9). The transverse diffuser (1) is arranged downstream of the turbine rotor blades (2). The transverse diffuser (1) has a curved diffuser channel (13) which opens into the exhaust gas collection chamber (9) at a diffuser channel outlet (17). A M/H ratio between an axial extension M of the exhaust gas collection chamber (9) and the turbine rotor blade height H has a value of 1.0?M/H?4.6 and a P/H ratio between a radial extension P of the diffuser arrangement (20) and the turbine rotor blade height H has a value of 2.7?P/H?4.9. A D/H ratio between a radial expansion D of the diffuser channel section (13) and the turbine rotor blade height H has a value of 2.5?D/H?3.Type: GrantFiled: October 17, 2018Date of Patent: December 28, 2021Assignee: ABB SCHWEIZ AGInventors: Stephan Senn, Christoph Mathey

Patent number: 11073048Abstract: The invention relates to an exhaust gas turbine, comprising a turbine wheel (7) with a multiplicity of moving blades (8) and an exhaust-gas outlet duct (15), which is arranged downstream of the moving blades of the turbine wheel. The exhaust-gas outlet duct (15) is delimited radially on the outside by an axial turbine diffuser (1) and radially on the inside, at least partially, by a spinner (2). The axial turbine diffuser (1) is formed by a number N>1 of successive conical diffuser segments. An axial diffuser opening angle A between successive diffuser segments is A>1.0°. A ratio L/H between an axial diffuser segment length L and an entry height H of the exhaust-gas outlet duct (15) is L/H>0.01. A ratio H/S between the entry height H of the exhaust-gas outlet duct and a maximum radius S of the spinner (2) is H/S>1.0. The spinner (2) is formed by a number P>1 of successive conical spinner segments. An axial spinner opening angle B between successive spinner segments is B>1.0°.Type: GrantFiled: September 5, 2018Date of Patent: July 27, 2021Assignee: ABB Schweiz AGInventors: Stephan Senn, Christoph Mathey

Patent number: 9893570Abstract: A system for contactless energy and data transfer has mobile and base parts. The mobile part contains a mobile part transmitter/receiver device transmitting and receiving a data signal, a mobile part transceiver and a current supply having a mobile part resonant circuit receiving an energy signal. The base part contains a base part resonant circuit for emitting the energy signal from an energy signal generator to provide a supply voltage to the current supply, a base part transmitter/receiver device receiving and transmitting the data signal, a base part transceiver, and a pulse width modulator. An impulse width modulator provides the pulse width-modulated signal which cyclically operates the energy signal generator to emit the energy signal in pulse bundles. A parameter specification provides a control signal setting at least one parameter of the pulse width-modulated signal to a value where sufficient energy transfer occurs to provide the supply voltage.Type: GrantFiled: January 28, 2016Date of Patent: February 13, 2018Assignee: Balluff GmbHInventors: Matthias Beyer, Stephan Senn, Fabian Kayser
