Vibration damper for vacuum pumps

A vibration damper disposed between a vacuum pump and a vacuum chamber, comprising:

• a first cylindrical hollow component arranged about an axis of symmetry and comprising a first end configured to be coupled to the vacuum pump, a second end located opposite the first end, a first toroidal semi-seat located at the second end, and a connecting component suitable for axially binding the first cylindrical hollow component to the second cylindrical hollow component;
• a second cylindrical hollow component arranged about the axis of symmetry at an axial distance from the first cylindrical hollow component and having a first end configured to be coupled to the vacuum chamber, a second end located opposite the first end, a toroidal semi-seat, and a connecting component suitable for axially binding the second cylindrical hollow component to the first cylindrical hollow component;
• a toroidal ring comprising an elastic material and arranged between the first cylindrical hollow component and the second cylindrical hollow component, wherein the toroidal ring assumes a resting configuration in response to a compression force directed along the axis of symmetry with a magnitude lower than a predetermined threshold, and assumes a compressed configuration in response to a compression force directed along the symmetry axis with a magnitude greater than the predetermined threshold, the resting configuration forming an axial connection between the first and the second cylindrical hollow components, and the compressed configuration forming a vacuum-tight axial connection between the first and the second component and preventing contact between the connecting components of the first cylindrical hollow component and the second cylindrical hollow component.
