Shock absorber including materials with shape memory

摘要

Damper of the type including a piston provided with channels fitted with elements made from a material with shape memory which act on their flow rate, characterised in that the channels are each provided with a planar stopper 50 which can move rotationally at the surface of the piston, brought to face the opening of the channel counter to a conventional helical antagonistic spring 51 by a helical spring 52 made from a material with single-effect memory whose action becomes predominant when the temperature rises. <IMAGE>
