<p>In an arrangement and device for a disturbance-eliminating valve or a method for eliminating disturbances in a valve in a vehicle, a partial step valve or pilot valve can be utilized that comprises a slide that can move in a space, in the medium, which slide is arranged to have an effect on a passage for the medium through the valve by means of guides that exert a valve pressure force on the slide that counteracts a force (Fl) exerted on the slide. By means of a part, the slide divides the space into a damping chamber and pilot pressure chamber (e and f respectively) arranged on the high pressure side or upstream of the piston that delimits the damping medium in two main chambers (19a, 19b). The pressure in the damping chamber is arranged, in a stationary control position of the slide, to assume a value that essentially corresponds to a pressure value in the pilot pressure chamber. In the event of an urged movement from the stationary control position, the slide is arranged to bring about a reduction in pressure over the said part. In the event of the said movement, the pressure in the damping chamber undergoes a change in value essentially proportional to the speed of movement of the body or the change in pressure and generates a damping force coinciding with the control force that counteracts the movements of the body and thereby brings about the disturbance elimination. Any admixture of gas in the medium is thereby prevented from changing the damping caused by the valve or from causing unwanted noises.</p> |
