The pressure increasing valve comprises a valve body internally provided with a first oil channel, a first oil cavity and a second oil channel which are sequentially connected, the first oil channel and the second oil channel serve as external oil ports of the valve body, the first oil channel serves as an oil outlet, the second oil channel serves as an oil inlet, a throttling hole is formed in the second oil channel, and the throttling hole is communicated with the first oil cavity and the second oil cavity. And the throttling hole is a dumbbell-shaped through hole with two large ends and a small middle part. By the adoption of the scheme, the second oil channel is arranged for oil inlet, the first oil channel is arranged for oil outlet, the throttling hole is formed in the second oil channel, and the dumbbell-shaped throttling hole is of a structure with the two ends large and the middle section suddenly changed and reduced, so that the throttling hole has a good throttling effect on hydraulic oil flowing through the second oil channel; that is to say, the throttling effect on hydraulic oil at the oil inlet of the pressure increasing valve is achieved through the throttling hole, and the pressure increasing valve can accurately control pressure and flow conveniently.

    本发明涉及一种用于制动系统的增压阀及增压模块,包括内部设有依次相连的第一油道、第一油腔和第二油道的阀体,第一油道和第二油道为阀体的外接油口,第一油道作为出油口,第二油道作为进油口,第二油道内设有节流孔,节流孔为两端大中部小的哑铃状通孔。采用本方案,通过设置第二油道进油,第一油道出油,且在第二油道内设置节流孔,哑铃状的节流孔呈两端大、中部截面突变并减小的结构,使得节流孔对流经第二油道的液压油起到较好的节流效果;即通过节流孔对增压阀进油处的液压油起到节流效果,便于增压阀对压力和流量的精确控制。
