Abstract
A shock and vibration insulator comprises an axial rigid element fastenable to an installation to be damped, a peripheral rigid element also fastenable to said installation and a radial rigid element extending radially between said elements and comprising a first radial part having an internal recess in the shape of an annular groove and a second radial part having a peripheral edge penetrating into said recess in which it can move radially so as to provide a fairly closed annular chamber.
Claims12
A shock and vibration insulator comprising:
- a closed volume including a peripheral rigid element defining, in part, said closed volume and being fastenable to a portion of an installation to be damped,
- an axial rigid element having one end disposed inside of said closed volume and another end disposed outside of said closed volume so as to be fastenable to another portion of the installation,
- said axial rigid element and said peripheral rigid element being movable relative to one another,
- a radial rigid element extending radially between said axial rigid element and said peripheral rigid element and being solidly fixed to one of said rigid elements, said radial rigid element being capable of being subjected to the thrust of a fluid and including:
- a. a first radial part having an internal recess in the shape of an annular groove, and
- b. a second radial part having a peripheral edge with said edge extending into said recess of said first radial part to define an annular chamber and said first and second radial parts being movable relative to one another to vary the volume of said annular chamber,
- said closed volume and said annular chamber being filled with fluid.
