Abstract
Abstract An insulator against vibrations having two rigid members for connection respectively to parts of a system subject to vibrations. One of the rigid members is of flattened shape and an envelope of deformable resilient material connects the two members. A portion of the envelope has the shape of a cup and receives at its centre the other of the rigid members, the envelope being filled with a high viscosity material.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
104 words
An insulator against vibrations, comprising in combination first and second rigid members adapted to be attached respectively to two parts of a system subjected to vibrations, for insulating one part from the other, one of the rigid members having a flattened shape, a sealed envelope of deformable resilient material connecting the two members with a portion at least of the said envelope turned inwardly to impart the shape of a cup to said envelope, said inwardly turned portion being flexible and receiving at its center the other of the said members, and a fluid of high viscosity filling the interior of the said envelope.
Claim 2
Dependent Claim
104 words
An insulator against vibrations, comprising in combination first and second rigid members adapted to be attached respectively to two parts of a system subjected to vibrations, for insulating one part from the other, one of the rigid members having a flattened shape, a sealed envelope of deformable resilient material connecting the two members with a portion at least of the said envelope turned inwardly to impart the shape of a cup to said envelope, said inwardly turned portion being flexible and receiving at its center the other of the said members, and a fluid of high viscosity filling the interior of the said envelope.
Claim 3
Dependent Claim
69 words
An insulator as claimed in claim 1, in which one of the said rigid members has the shape of a flattened base having a dimension which is large with respect to the dimension of the other rigid member which is retained in the center of said inwardly turned portion of the envelope, a cylindrical portion of the envelope being connected to the periphery of the said flattened rigid member.
Claim 4
Dependent Claim
26 words
An insulator as claimed in claim 2, in which the said cylindrical portion of the envelope is moulded over and round a rigid substantially cylindrical core.
Claim 5
Dependent Claim
41 words
An insulator as claimed in claim 3, in which the said rigid cylindrical core carries a flange extending parallel with the periphery of the said flattened rigid member to which it is attached with at least one sealing rib interposed therebetween.
Claim 6
Dependent Claim
23 words
An insulator as claimed in claim 1 in which the two rigid members are aligned along an axis of revolution of the insulator.
Claim 7
Dependent Claim
26 words
An insulator as claimed in claim 1 in which the viscosity of the material filling the interior of the envelope lies between 50,000 and 1,500,000 centistokes.
Claim 8
Dependent Claim
16 words
An insulator as claimed in claim 6 in which the said material of a silicone grease.
Claim 9
Dependent Claim

An insulator as claimed in claim 1, in which the envelope is made of silicone elastomer.
Claim 10
Dependent Claim
23 words
an insulator as claimed in claim 1 which includes a spring the ends of which bear respectively against the said two rigid members.
Claim 11
Dependent Claim
16 words
An insulator as claimed in claim 9 in which the spring is conTained inside the envelope.
Claim 12
Dependent Claim
33 words
An insulator as claimed in claim 1 in which one portion of said other rigid member, positioned inside the envelope, supports a ring extending perpendicular to the axis of the said rigid member.
Claim 13
Dependent Claim
15 words
An insulator as in claim 11, in which the ring supports a resilient peripheral cladding.
Claim 14
Dependent Claim
29 words
An insulator as claimed in claim 1, in which one portion of said other rigid member, positioned inside the envelope, is integral with a cushion of knitted metal wire.
