Abstract (en)

[origin: DE19721755A1] The invention relates to a reaction device on a hydraulic servo valve arrangement, especially for power steering devices of motor vehicles. Said servo valve arrangement is configured in the manner of a rotary valve arrangement, comprising a rotary valve and a control bushing, said control bushing encompassing said rotary valve coaxially and being able to pivot in relation thereto. Inwardly axial V-grooves are located on a section of the bushing which is connected to the control bushing. Reaction bodies can be pressed into said grooves by means of controlled hydraulic pressure. Said reaction bodies are arranged radially on a shaft part, said shaft part being rotationally fixed to the rotary valve.
