摘要

Adjusting device comprises a cylinder (1) filled with a working fluid, a rod (3) inserted into the cylinder, a piston (4) connected to the rod, a damping part (4a, 4b) arranged on the piston to produce a damping force via the passage of the working fluid, a low pressure chamber (16) arranged on the outer side of the cylinder and partially filled with a low pressure gas, a high pressure chamber (18) arranged on the outer side of the cylinder and partially filled with a high pressure gas, a pump chamber for adjusting the height of a motor vehicle, a communication path (5a) and a valve body (20) for increasing or reducing the channel surface of the communication path. Preferred Features: The valve body has a guiding part which is freely guided into a pilot chamber.
