TRYCKREGLERINGSANORDNING FOR ETT HYDRAULISKT BROMSSYSTEM I ETT FORDON

摘要

There is disclosed a dual-circuit brake-force distributor wherein the control force of one circuit is transmitted to the other circuit through a floating intermediate piston. In order to achieve a highly sensitive control, the intermediate piston is provided with a large cross-sectional area. In the event of failure of the one circuit, the intermediate piston will become blocked and the control force will be transmitted through an auxiliary piston having a smaller cross-sectional area. By this arrangement upon failure of the one circuit a sufficient amount of braking pressure can still build up in the other intact braking circuit.
