Abstract
The present invention relates to devices for damping the movement of a body Co between two positions at the end of travel. The device according to the invention is essentially characterized in that it comprises two abutments B, B, a cylinder, a wallclosing off the endof the cylinder, a pistondelimiting a chamberwith variable volume, a cylinderwith an external section at most equal to the internal section of the cylinder, a mounting unit for mounting the cylinderin cooperation with the pistonso that the latter closes off the endof this cylinder, a pistondelimiting a chamberwith variable volume, a first fluid Li filling the two chambers, a communicating unitfor communication under pressure loss between the chambers, an abutmentmounted in cooperation with the pistonso that this abutmenthas a movement correlative with that of the piston, and a connecting unitfor connecting the cylinderto the body Co. Application notably to the control for opening and closing an aircraft door.
