<p>1. Bitubular shock absorber which is arranged between two parts, in particular vehicle parts, the distance between which is changeable, and has a piston (5, 25) carried by a piston rod (7, 27), which piston separates two fluid-filled inner chambers (3, 4; 23, 24) from one another and is provided with a connecting channel controlled by a nonreturn valve (10, 30), and with a cylinder base (8, 28) which likewise has a connecting channel controlled by a nonreturn valve (9, 29) as a connection to an outer chamber concentrically surrounding the inner chambers (3, 4; 23, 24), a single restriction (14, 34) of the shock absorber (1, 21) being provided between the inner chamber (3, 23), penetrated by the piston rod (7, 27), and the outer chamber (12, 32), characterized in that, during the compression and rebounding of the shock absorber, the flow through this restriction is always in the same direction and in that a rheological fluid is used as fluid, in that, furthermore, electrodes (22, 33, 35) for establishing an electrostatic field are provided and in that the single restriction (34) is constructed as a narrow passage between the electrodes.</p> |
