MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202647126138 A) filed by Kessel Se Co. Kg on October 22, 2026, for Vertical Backflow Preventer With A Valve Tappet Guide Which Is Shielded On The Outlet Side.
Inventor includes Kessel, Bernhard.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The invention relates to a backflow preventer for a vertical installation in a waste water pipe gradient. The backflow preventer has a waste water inlet followed by a waste water outlet in the direction of the waste water passage path of the backflow preventer, and the waste water passage path points at least partly in the direction of gravity when the backflow preventer is in a vertical installation orientation. The backflow preventer has a closable valve unit between the waste water inlet and the waste water outlet, and the valve unit allows a flow of waste water in the direction of the waste water passage path by means of a sealing interaction between a movably guided valve tappet and a valve seat opening when the backflow preventer is in a vertical installation orientation and blocks a flow of waste water in the direction opposite the waste water passage path in a backflow situation. The guide of the valve tappet is provided on the outlet side of the valve seat opening in a region which is shielded from the valve seat opening by the valve tappet. The invention also relates to a corresponding waste water lifting system.
