Abstract:
1. A vibration damper comprising: a first cylindrical hollow component arranged about an axis of symmetry and comprising a first end configured to be coupled to a vacuum pump, a second end located opposite the first end, a toroidal semi-seat located at the second end, and a connecting component located at the second end; a second cylindrical hollow component, arranged about the axis of symmetry and having a first end configured to be coupled to a vacuum chamber, a second end located opposite the first end, a toroidal semi-seat located at the second end, and a connecting component located at the second end; at least one intermediate component arranged about the axis of symmetry between the first cylindrical hollow component and the second cylindrical hollow component and having a first end configured to be coupled to the first cylindrical hollow component, a second end configured to be coupled to the second cylindrical hollow component, a first toroidal semi-seat located at the first end, a first connecting component located at the first end, a second toroidal semi-seat located at the first end, and a second connecting component located at the second end; a first toroidal ring comprising an elastic material and disposed between the toroidal semi-seat of the first cylindrical hollow component and the first toroidal semi-seat of the at least one intermediate component, wherein the first 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 axis of symmetry with a magnitude greater than the predetermined threshold, the resting configuration forming an axial connection between the first cylindrical hollow component and the at least one intermediate component such that the connecting component of the first cylindrical hollow component is in direct contact with the first connecting component of the at least one intermediate component, and the compressed configuration forming a vacuum-tight axial connection between the first cylindrical hollow component and the at least one intermediate component such that the connecting component of the first cylindrical hollow component is not in direct contact with the first connecting component of the at least one intermediate component; a second toroidal ring comprising an elastic material and disposed between the toroidal semi-seat of the second cylindrical hollow component and the second toroidal semi-seat of the at least one intermediate component, wherein the second toroidal ring assumes a resting configuration in response to the compression force directed along the axis of symmetry with a magnitude lower than a predetermined threshold, and assumes a compressed configuration in response to the compression force directed along the axis of symmetry with a magnitude greater than the predetermined threshold, the resting configuration forming an axial connection between the second cylindrical hollow component and the at least one intermediate component such that the connecting component of the second cylindrical hollow component is in direct contact with the second connecting component of the at least one intermediate component, and the compressed configuration forming a vacuum-tight axial connection between the second cylindrical hollow component and the at least one intermediate component such that the connecting component of the second cylindrical hollow component is not in direct contact with the second connecting component of the at least one intermediate component.
