Abstract:
1. A valve plate suspension system comprising a valve plate supported on at least one valve rod by a crossbar extending transverse to the valve rod, the crossbar is connected to the valve plate at lateral valve-plate connection points and the at least one valve rod is connected to the crossbar at at least one valve-rod connection point of the crossbar lying between the lateral valve-plate connection points, and the crossbar has a spacing (a) from the valve plate in a middle section of the crossbar, with the middle section encompassing the at least one valve-rod connection point and adjacent sections of the crossbar on both sides of the at least one valve-rod connection point, and the valve plate is pivotable about a pivot axis that extends at a right angle to the valve rod relative to the at least one valve rod through a torsion of the crossbar that occurs when at least one end of the valve rod is fixed and the valve plate pivots relative to the at least one valve rod around the pivot axis so that the crossbar twists, a cross-section of the crossbar being progressively rotated with larger angles of rotation with increasing distance from the fixed end of the valve rod.
