Abstract
Official abstract text for this publication.
A vehicle brake system comprises a master brake cylinder having an input piston and master piston and connected to a wheel brake device, a reaction force generating device for generating a reaction force pressure corresponding to a displacement amount of the input piston, a change over valve provided in an open passage branched from a hydraulic conduit connecting the reaction force generating device to the reaction force chamber defined by the input piston and the change over valve connected to a reservoir, a brake force boosting device for applying an assisting pressure to a master piston, an assisting pressure limit judging portion for judging whether the assisting pressure has reached to an assisting limit pressure, and a change over controlling portion for changing over the change over valve to an open state when the assisting pressure limit judging portion judges that the assisting pressure has reached the assisting limit pressure.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle brake system comprising: a master brake cylinder having an input piston inserted into an input cylinder bore and slidable therein in an axial line direction in response to operation of a brake pedal and a master piston inserted into a pressure cylinder bore and arranged with a predetermined distance apart from the input piston in an advancing direction thereof, the master piston being slidable in the pressure cylinder bore in the axial line directi…
