Controlled oscillating damper

摘要

Oscillating damper comprising: a housing (12) defining a chamber (14) filled with damping fluid, an oscillating plate (22), movable within the chamber (14) and placed so as to divide the chamber (14) into two sections of variable volume (24, 26), and at least one passage (28) created in the oscillating plate (22) to enable the fluid to pass from one section to the other during the motion of the plate (22). The damping fluid is a magneto-rheological or electro-rheological fluid and an electrically-controlled excitation device (30) is placed in correspondence with the passage (28) to control the outflow resistance of fluid passing through the passage (28).
