Abstract
Abstract A vibration damper of the type including a supporting flange, a pair of damping elements applied, respectively, against an upper and a lower face of the supporting flange, a mounting flange supported on the upper damping element and an abutment which is applied against the lower face of the lower damping element. The mounting flange has a central part extending through the damping elements and the supporting flange and connecting the mounting flange to the abutment. The connecting part is fixed both rotationaly and axially to the mounting flange and is connected to the abutment by a screw-thread. The abutment is secured against rotation relatively to the supporting flange and is preferably located with respect to the supporting flange to permit axial movement of the abutment relatively to the supporting flange.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
158 words
A vibration damper including a base flange having a threaded bore, a supporting flange having a generally central opening, said supporting flange threadably engaged with said base flange bore wherein portions of said supporting flange are upwardly spaced over said base flange and whereby said supporting flange is axially adjustable with respect to said base flange, an upper and a lower damping element each having a central opening respectively engaging an upper and a lower face of said supporting flange, a mounting flange supported on top of said upper element, said mounting flange having a downwardly extending central part positioned through said openings in said elements and siad supporting flange, an abutment having an upper surface positioned against the lower face of said lower element, said central part of said mounting flange threadably connected to said abutment, and means between said abutment and said supporting flange for permitting relative axial movement therebetween but preventing relative rotational movement therebetween.
Claim 2
Dependent Claim
158 words
A vibration damper including a base flange having a threaded bore, a supporting flange having a generally central opening, said supporting flange threadably engaged with said base flange bore wherein portions of said supporting flange are upwardly spaced over said base flange and whereby said supporting flange is axially adjustable with respect to said base flange, an upper and a lower damping element each having a central opening respectively engaging an upper and a lower face of said supporting flange, a mounting flange supported on top of said upper element, said mounting flange having a downwardly extending central part positioned through said openings in said elements and siad supporting flange, an abutment having an upper surface positioned against the lower face of said lower element, said central part of said mounting flange threadably connected to said abutment, and means between said abutment and said supporting flange for permitting relative axial movement therebetween but preventing relative rotational movement therebetween.
Claim 3
Dependent Claim
23 words
A vibration damper according to claim 1, in which a releasable arresting member is provided between the mounting flange and the supporting flange.
Claim 4
Dependent Claim
40 words
A vibration damper according to claim 1 in which at least one of the mounting flange and the supporting flange is designed to be substantially cylindrical at its circumference and is provided with recesses for engagement by a hook spanner.
Claim 5
Dependent Claim
28 words
A vibration damper according to claim 3, in which the recesses are grooves in the substantially cylindrical circumference and extending parallel to the axis of the relevant flange.
Claim 6
Dependent Claim
74 words
A vibration damper according to claim 2 in which the arresting member is an arresting spring and is provided on one of the mounting flange and the supporting flange and which is capable of swivelling into and out of engagement with a groove on the other of said flanges, said groove being one of a plurality of grooves in a substantially cylindrical surface of said other flange and extending parallel to the axis thereof.
Claim 7
Dependent Claim
22 words
