Publication number: 20230304503Abstract: A fan wheel including a fan wheel hub with fan blades supported rotatably on the fan wheel hub so as to extend radially therefrom, and a fan wheel drive accommodated in the fan wheel hub so as to be rotatable relative thereto within a limited angular range and connected to the fan blades for a corresponding rotation of the fan blades about their longitudinal axes, whereby the flow direction of the fan wheel is reversible by an inertia-based rotation of the fan wheel relative to the fan wheel drive.Type: ApplicationFiled: June 2, 2023Publication date: September 28, 2023Applicant: IE ASSETS GMBH & CO. KGInventors: KARL HAEGELE, MARKUS LECHLER, SAMUEL ARNOLD

Patent number: 11708836Abstract: A fan wheel with a hub is centrally supported with respect to a drive and coaxially rotatable with the hub between stops relative to the hub. The fan wheel having fan blades extending radially from the hub are rotatable about their axes in a range delimited by the stops. Overlaying the rotational support between the stops of the hub, a rotational support between the hub and the drive is provided including a planetary drive in operative arrangement with an adjustment control ring of the driven hub. The fan blades are rotatable in the hub about their blade axes, and adjustment of the blade angles of the fan blades via drive connections to the adjustment control ring, which connections operate in a manner superimposed on one another starting from the drive of the fan wheel.Type: GrantFiled: December 13, 2021Date of Patent: July 25, 2023Assignee: IE ASSETS GMBH & CO. KGInventors: Karl Haegele, Markus Lechler

Patent number: 11365749Abstract: A fan wheel to be driven in only one rotational direction comprising a central drive unit. A hub positioned coaxially relative to the drive unit and comprising radial fan blades mounted in the hub. The fan blades engage at the base end of the hub between two drive tracks which are fixed relative to the drive unit and are arranged coaxially opposite one another in the direction of the axis of rotation of the fan wheel. The fan blades can be adjusted in terms of their blade angle, into opposing blowing directions, by being driven by a respective one of the drive tracks about their blade axis via a reversal plane which extends perpendicular to the plane of rotation of the fan wheel.Type: GrantFiled: September 18, 2020Date of Patent: June 21, 2022Assignee: IE ASSETS GMBH & CO. KGInventors: Karl Haegele, Markus Lechler
