Mounting of a valve plate on a valve rod
First Claim
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, andthe 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.

Abstract
A mounting of a valve plate (1) on a valve rod (2) using a cross member (3) extending transversely with respect to the valve rod (2) is provided. The cross member (3) is connected at a central connecting point (4) to the valve rod (2) and is connected at least two lateral connecting points (5, 6), which are situated on both sides of the central connecting point (4), to the valve plate (1). The cross member (3) has a spacing (a) from the valve plate (1) in a central section (17) which comprises the central connecting point (4) and sections of the cross member (3) adjacent to the central connecting point (4) at both sides. By a twisting of the cross member (3), the valve plate (1) can be pivoted relative to the valve rod (2) about a pivot axis (19) which is at right angles to the valve rod.

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.

13. Vacuum valve comprising a valve plate and at least one valve rod on which the valve plate is suspended and by which the valve plate can be adjusted between an open position in which the vacuum valve is opened and a closed position in which the vacuum valve is closed and the valve plate seals a valve opening, a 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 that encompasses the at least one valve-rod connection point of the crossbar and adjacent sections of the crossbar on both sides of this connection point, and
the valve plate is pivotable relative to the at least one valve rod by 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 about a pivot axis that extends at a right angle to the valve rod 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 at least one valve rod.
