MUMBAI, India, Sept. 28 -- Intellectual Property India has published a patent application (202647112175 A) filed by Flender Gmbh on September 18, 2026, for Pitch Tube For Conducting Supply Lines Of A Blade Pitch Angle Controller For A Wind Turbine.
Inventors include Knig, Christian; and Trivic, Daniel.
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: The invention relates to a pitch tube (26) for conducting supply lines of a blade pitch angle controller for a wind turbine (10), provided with a first tube piece (48), a second tube piece (50), and a sealing sleeve (46) received between the first tube piece (48) and the second tube piece (50) and positioned in the radial direction at least partially in a common radial region with the first tube piece (48) and with the second tube piece (50) in order to form a sealing surface (44) for a contacting shaft seal. By reducing the sealing functionality of the multi-part pitch tube (26) to the sealing sleeve (48), good sealing of the pitch tube (26) in the wind turbine (10) is made possible in a cost-effective manner even under restricted installation space conditions.
