The invention relates to a working valve block and a braking energy supply system.The working valve block comprises a valve body, an oil inlet valve, an energy accumulator and a three-way valve, the oil inlet valve, the energy accumulator and the three-way valve are arranged on the valve body, the valve body is provided with a main oil inlet channel and a main oil outlet channel, the main oil inlet channel is used for communicating a liquid pump of the braking energy supply system with the energy accumulator, and the oil inlet valve is arranged on the main oil inlet channel; therefore, on-off of the main oil inlet channel is controlled. The main oil outlet channel is provided with a first oil outlet and a second oil outlet, and the three-way valve is arranged on the main oil outlet channel so as to control the energy accumulator to be communicated with a driving device of the braking energy supply system through the first oil outlet of the main oil outlet channel or control the energy accumulator to be communicated with an oil return device of the braking energy supply system through the second oil outlet of the main oil outlet channel. According to the working valve block and the braking energy supply system, the problem that the installation difficulty of the energy accumulator and the multiple switch valves is too large is solved.
