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 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 to control on-off of the main oil inlet channel. 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. The working valve block further comprises a one-way liquid inlet structure, and the one-way liquid inlet structure is arranged at the end, close to the energy accumulator, of the main oil inlet channel so that pressure oil can flow from the main oil inlet channel to the energy accumulator in a one-way mode. According to the working valve block and the braking energy supply system, the problem that the oil inlet valve is prone to damage is solved.
本申请涉及工作阀块及制动供能系统,工作阀块包括阀体、进油阀、蓄能器和三通阀,阀体设有主进油通道和主出油通道,主进油通道用于连通制动供能系统的液泵和蓄能器,进油阀装设于主进油通道,以控制主进油通道的通断。主出油通道具有第一出油口和第二出油口,三通阀装设于主出油通道,以控制蓄能器通过主出油通道的第一出油口连通制动供能系统的驱动装置,或者控制蓄能器通过主出油通道的第二出油口连通制动供能系统的回油装置。工作阀块还包括单向进液结构,单向进液结构设于主进油通道靠近蓄能器的一端,以使压力油液从主进油通道至蓄能器单向流动。本申请提供的工作阀块及制动供能系统,解决了进油阀容易发生损坏的问题。
