Abstract:
A hydraulic control circuit particularly for use in motor vehicles for the orientation of headlamps in which there is a flexible tube enclosing a transmission medium whereof the volumetric coefficient of expansion is equal to three times the linear expansion of the tube. This transmission medium consists of a number of solid elements located end-to-end within the tube and being surrounded by a hydraulic liquid which fills the spaces between the tube and the solid elements. These elements are contiguous or joints and their contacting surfaces are rounded to permit relative rolling. The solid elements may be cylindrical with rounded ends or spheres.
