| 摘要 |
<p>The present invention relates to a device for elastic linking between two parts, notably the main gearbox and the fuselage of a rotary-winged aircraft, such as a helicopter, comprising first and second internal and external coaxial tubular bodies, and elastic return means, housed in the annular space existing between the said first and second bodies and linking them in a leaktight way.
<??>According to the invention, the said annular space (6) is separated, by the said elastic return means (7, 8, 9), into first (6A) and second (6B) chambers filled with a liquid, the first (6A) and second (6B) chambers being in communication with the interior (17) of the said first body (2), inside the said first body (2) is provided a liquid distributor (19) comprising two pistons (20, 21), linked by a piston rod (22) and separated from one another by the distance I separating the orifices of the first (6A) and the second (6B) chambers, and elastic return and damping means (26, 27; 28, 29) of the said distributor (19) are provided.
