Abstract

A flap transfer valve is disclosed. An elongated first opening can be closed by an elongated valve closure beam, which can be pivoted via a pivoting bearing between a closed and open position. A shaft can be rotated by a drive and is operatively connected to the valve closure beam such that rotation of the shaft causes the valve closure beam to pivot. The pivoting bearing is formed by at least three bearing elements which are distributed at a distance from one another along the shaft axis in the valve housing, and on which the valve closure beam and the shaft are mounted. The shaft axis is at a distance from the pivoting axis. First arms are arranged on the shaft to provide a force to the rear face of the valve closure beam to pivot the valve closure beam. According to one development of the invention, the valve closure beam, the pivoting bearing and the shaft are arranged on a valve cover in a gas-tight valve housing, wherein the shaft, the pivoting bearing and the valve closure beam can be decoupled from the valve housing.
