The invention belongs to the technical field of pressure increasing valves for automobile brake systems, and discloses a pressure increasing valve which is characterized in that a first through hole of the valve body of the pressure increasing valve is used for communicating with a wheel cylinder; a second through hole in a base is used for communicating with a brake main cylinder; a valve body assembly is configured to achieve the communication between the second through hole and the first through hole; a third through hole in the side wall of the base is used for communicating with the wheel cylinder; a one-way valve body is formed by a plastic material through integrated injection molding; two ends of a one-way valve hole in the base communicate with the third through hole and the brake main cylinder correspondingly; through a brake fluid in the brake main cylinder, the one-way valve body can be driven to be inserted into the one-way valve hole, and thus the inserted state of the one-way valve body can be achieved; through a brake fluid in the wheel cylinder, the one-way valve body can be driven to be partially separated from the one-way valve hole, and thus the separated state of the one-way valve body can be achieved; and the height of the one-way valve body is greater than the axial length of the one-way valve hole. According to the pressure increasing valve, the weight of the one-way valve body is light; the driving force used for driving the one-way valve body to be inserted into or partially separated from the one-way valve hole is small; the response speed of the one-way valve body is high; the machining cost is low; and the practicability is high.

    本发明属于汽车制动系统用增压阀技术领域,公开了一种增压阀,该增压阀的阀体的第一通孔用于连通轮缸;底座上的第二通孔用于连通制动主缸,阀体组件被配置为能使第二通孔与第一通孔连通,底座的侧壁上的第三通孔用于连通轮缸;单向阀体由塑胶材料一体注塑成型,底座上的单向阀孔的两端分别与第三通孔和制动主缸连通,制动主缸内的制动液能驱动单向阀体插接于单向阀孔中,使单向阀体具有插接状态,轮缸内的制动液能驱动单向阀体部分脱离单向阀孔,使单向阀体具有分离状态,单向阀体的高度大于单向阀孔沿轴向的长度。该增压阀,单向阀体的质量轻,驱动单向阀体插接或部分脱离于单向阀孔的驱动力小,单向阀体的反应速度快,加工成本低,实用性强。
