Patent number: 11555507Abstract: The invention relates to a turbocompressor (1) comprising a compressor housing (2) and a compressor wheel (4) with blades (5). The compressor wheel (4) is rotatably mounted relative to the compressor housing (2) and is arranged such that the exposed upper edges of the blades (5) are spaced from a compressor housing (2) wall (3) facing the blade upper edges across a head gap (7), wherein both the upper edges of the blades (5) as well as the housing wall (3) have at least one recess (11, 13) and at least one elevation (10, 14) over the respective Meridian contour, said recess and elevation interacting locally such that the head gap (7) defines a Z-shaped course in the region of the recesses (11, 13) and the elevations (10, 14) when viewed on a Meridian plane.Type: GrantFiled: November 29, 2019Date of Patent: January 17, 2023Assignee: ebm-papst Mulfingen GmbH & Co. KGInventors: Markus Engert, Angelika Klostermann, Daniel Conrad

Patent number: 11519424Abstract: A return geometry fluidically connects a first and a second compressor stage of the turbocompressor. The return geometry has multiple partial helices that are evenly or unevenly distributed in the circumferential direction. The multiple partial helices extend at least in part in the circumferential direction. They form flow channels that extend at least in some sections, separately from each other, to fluidically connect the first and second compressor stages.Type: GrantFiled: November 15, 2019Date of Patent: December 6, 2022Assignee: ebm-papst Mulfingen GmbH & Co. KGInventors: Markus Engert, Angelika Klostermann, Daniel Conrad

Patent number: 11365741Abstract: An axial fan for use with a wall ring plate includes a housing having an inlet region and a rotor. The rotor has an increased rotor diameter compared to a standardised rotor diameter. On the inlet side, the inlet region has a tapered section that narrows in an arched manner in a cross-sectional view from an inlet diameter to a wall ring diameter. The axial width and radial length of the tapered section are formed in a predetermined ratio.Type: GrantFiled: August 13, 2015Date of Patent: June 21, 2022Assignee: ebm-papst Mulfingen GmbH & Co. KGInventors: Daniel Gebert, Thorsten Pissarczyk, Angelika Klostermann, Katrin Bohl, Markus Engert, Oliver Haaf, Marc Schneider

Publication number: 20220025902Abstract: A ventilation unit (1) is formed by at least one fan (2), a heat exchanger, axially spaced from the fan (2), and a housing (3). The housing (3) has a first housing section (4), with a constant flow cross-section, where the heat exchanger is arranged. A second housing section (5) adjoins the first section (4) in the axial flow direction. The fan (2) is arranged on the second housing section (5) in the axial flow direction. During operation, the fan conveys air through the heat exchanger, arranged in the first housing section (4), and through the second housing section (5). The flow cross-section of the second housing section (5) is reduced in the flow direction from the first housing section (4) to the fan (2) by an adaptation to the form of housing wall sections (6, 6?) of the second housing section (5).Type: ApplicationFiled: December 10, 2019Publication date: January 27, 2022Inventors: Markus ENGERT, Daniel CONRAD, Dimitri MEHLMEISTER

Patent number: 10107306Abstract: A housing for a fan or blower, in particular an axial fan, includes a wall ring (2) having an inlet nozzle section (3), an outer diffuser (6) having an inlet flow opening (7) and an outlet flow opening (8), and a holder for an electric motor (9) of the fan. The holder is arranged in an inner space of the housing. The outer diffuser (6) is formed by at least two partial ring sections that are connected to the outer circumferential surface via mechanical connection elements. The holder includes several struts (14) that are fastened to an inner circumferential surface of the outer diffuser (6) by one end, are circumferentially spaced apart, and are fastened in the edge region of the inlet flow opening (7). The struts can be installed by their other end to a motor flange (16) of the motor housing (17) of the electric motor (9).Type: GrantFiled: April 12, 2013Date of Patent: October 23, 2018Assignee: EBM-PAPST MULFINGEN GMBH & CO. KGInventors: Oliver Haaf, Matthias Maschke, Dieter Best, Thomas Sauer, Sebastian Bundschuh, Sven Beck, Markus Engert, Jürgen Schöne, Alexander Lust, Sebastian Hoss

Patent number: 10072671Abstract: A diffuser (3) for a fan (2) of axial, radial or diagonal type of construction, has an inlet opening (10) and having an outlet opening (20) for a gaseous medium which flows through a diffuser interior (I), which is enclosed by an outer housing (30), in an axially oriented main flow direction (S) from the inlet opening (10) to the outlet opening (20). The cross section of the diffuser interior (I) increases from the cross section (11) of the inlet opening to the cross section (21) of the outlet opening (20), wherein the outer housing (30) forms an outer diffuser part (AD) which delimits the diffuser interior (I) to the outside. Along the main flow direction (S), the cross section of the outer diffuser part (AD) changes from a circular cross section (31) at the inlet opening (10) to a non-circular cross section (32) at the outlet opening (20).Type: GrantFiled: December 16, 2011Date of Patent: September 11, 2018Assignee: ebm-papst Mulfingen GmbH & Co. KGInventors: Markus Engert, Erik Reichert, Oliver Haaf, Christian Pfaff, Marc Schneider, Jürgen Schöne, Katrin Bohl, Sven Beck, Dieter Best, Tobias Ehmann, Alexander Frank, Erhard Gruber, Matthias Maschke, Thomas Sauer
