Abstract
The feed line for a hydraulic system, in particular of a motor vehicle, is formed, at least over part of its longitudinal extent, by a dimensionally variable body. The wall of the dimensionally variable body is elastically deformable, at least in regions, so that, when the flow passes through the dimensionally variable body, the cross section of the dimensionally variable body can be varied as a function of the pressure of the hydraulic medium.
Claims18
A feed line for a hydraulic system, comprising:
- a dimensionally variable body forming the feed line, at least over a part of a longitudinal extent thereof, said dimensionally variable body having an elastically deformable body wall, at least in regions thereof, and a twist angle deviating from a neutral angle being 54.7°;
- and
- wherein, when hydraulic medium flow passes through said dimensionally variable body, a cross section of said dimensionally variable body is varied as a function of a pressure of the hydraulic medium.
