Braking servo with emergency braking assistance function has control valve regulating braking force provided with combined spring and coupling element component

摘要

The braking servo (10) has a control valve (22) for regulating the servo braking force provided with a control valve housing (18), an input element (24), an output element (34) and an intermediate pressure piece (38) acting on the output element. The relative movement between the pressure piece and the valve housing, caused by the input element, facilitated by a combined spring and coupling element component (52).
