Abstract
A bypass valve-delay valve assembly for an electric-hydraulic braking system of an electrically driven vehicle which includes a bypass valve section in which the hydraulic braking circuit ducts are obstructed by a solenoid operated valve activated by an electric signal generated by brake pedal depression, and a delay valve section in which the hydraulic fluid is obstructed by a delay valve arranged in a regulator piston whose maximum stroke equals the pressure corresponding to the maximum energy recovery performance generated by the electric drive motors' braking action. Pressure exceeding the maximum energy recovery performance of the drive motors causes the delay valve to open adding hydraulic braking to the electric drive motor braking.
