Abstract

A flap transfer valve is disclosed. An elongated first opening can be closed by elongated valve closure beam pivoted between a closed position and an open position. A shaft can be rotated about a shaft axis by a drive and is operatively connected to the valve closure beam to cause the valve closure beam to pivot. The valve closure beam, the pivoting bearing and the shaft are arranged on a valve cover in a gas-tight valve housing. The shaft, the pivoting bearing and the valve closure beam can be decoupled from the valve housing. 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.
