Abstract
Abstract Damper of vibrations between two elements comprising a center rod adapted to be connected to one of the elements and a mount surrounding the rod and adapted to be connected to the other element. The rod and mount are interconnected by two elastically yieldable bell-shaped membranes. The latter have at their apices apertures in which the rod is engaged and are connected to the mount at their peripheries.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
71 words
A damper of vibrations between two elements, comprising a center rod adapted to be rendered integral with one of said elements, a mount surrounding the rod and adapted to be rendered integral with the other element, two elastically yieldable bellshaped membranes interconnecting said rod and said mount, each membrane having an apex at which means define an aperture in which said rod is engaged and a periphery connected to the mount.
Claim 2
Dependent Claim
71 words
A damper of vibrations between two elements, comprising a center rod adapted to be rendered integral with one of said elements, a mount surrounding the rod and adapted to be rendered integral with the other element, two elastically yieldable bellshaped membranes interconnecting said rod and said mount, each membrane having an apex at which means define an aperture in which said rod is engaged and a periphery connected to the mount.
Claim 3
Dependent Claim
24 words
A damper as claimed in claim 1, wherein said rod comprises at its ends flanges adapted to retain said apices of said membranes externally.
Claim 4
Dependent Claim
20 words
A damper as claimed in claim 2, wherein said apices of said membranes are fixed to said flanges by adhesion.
Claim 5
Dependent Claim
20 words
A damper as claimed in claim 2, wherein said apices of said membranes are fixed to said flanges by vulcanization.
Claim 6
Dependent Claim
31 words
A damper as claimed in claim 1, wherein said rod comprises two parts screwed one into the other so as to make it possible to apply a prestressing to said membranes.
Claim 7
Dependent Claim
32 words
A damper as claimed in claim 1, wherein said rod further comprises shoulders adapted to connect said apices of said membranes to said rod so that said membranes move with said rod.
Claim 8
Dependent Claim
25 words
A damper as claimed in claim 1, wherein said mount comprises two annular recesses in which said peripheries of said membranes are held in position.
Claim 9
Dependent Claim
55 words
A damper as claimed in claim 7, wherein the mount comprises a center plate having an aperture through which said rod extends, two side walls in clamped relation to said plate and having curved inner portions, said annular recesses being defined by opposed faces of said plate and said curved portions of said side walls.
Claim 10
Dependent Claim
27 words
A damper as claimed in claim 8, wherein said membranes bear on said opposed faces of said plate and on said curved portions of said side walls.
Claim 11
Dependent Claim
15 words
A damper as claimed in claim 7, wherein said mount is in a single piece.
Claim 12
Dependent Claim
17 words
A damper as claimed in claim 7, wherein said curved portions terminate in inner annular horizontal flanges.
