<p>Between the body (4) of a piston (1) and the partially spherical foot (6) of a connecting rod (3), the forces are transmitted by a sealed shell (8) limiting with the foot (6) a space which receives oil through a non-return valve (11). This shell (8) is free to move over its surface (17) opposite the abovementioned space and it is rendered integral with the body for example by the clamping of a collar (18) surrounding this shell (8). <IMAGE></p> |
