The invention relates to the technical field of automobile parts, in particular to a three-way check valve for automobile vacuum braking. The three-way check valve for automobile vacuum braking comprises a middle shell, side shells and rubber diaphragms, wherein the side shells are arranged on the two sides of the middle shell, the interiors of the side shells, the interiors of the side shells communicate with the interior of the middle shell, and the rubber diaphragms are arranged at the connection positions between the side shells and the middle shell separately. According to the three-way check valve, two check valves (side shells) and a three-way structure (middle shell) are integrated, and the complexity of a pipeline is greatly reduced; through design of a sealing structure, accurate location and accurate action of the diaphragms can be ensured, and therefore sufficient air flow and sealing effect in the pipeline are ensured; and the driving experience of a driver is effectively improved.

    本发明涉及汽车零部件的技术领域,更具体地,涉及一种用于汽车真空制动的三通单向阀。一种用于汽车真空制动的三通单向阀,其中,包括中壳体、侧壳体、橡胶膜片,所述的侧壳体设于中壳体的两侧部而且侧壳体内部与中壳体内部相连通,所述的橡胶膜片分别设于侧壳体与中壳体之间的连接处。本发明集成了两个单向阀(侧壳体)和一个三通结构(中壳体),大大降低了管路的复杂程度;密封结构的设计可保证膜片的精准定位及精准动作,从而保证管路内充足的气流量和密封效果,有效改善驾驶者的驾车体验。
