The invention relates to the field of breather valves. The invention discloses a diaphragm type oil pump breather valve. The breather valve comprises a valve body (1), a diaphragm cavity (2) is formedin the valve body (1), a diaphragm (3) is installed in the diaphragm cavity (2) to divide the diaphragm cavity (2) into a first cavity (201) and a second cavity (202), and the diaphragm (3) is deformed by a pressure difference between the first cavity (201) and the second cavity (202), and the diaphragm (3) communicates with the first cavity (201) and the second cavity (202). Through the deformation of the diaphragm, the due functions of the breather valve are realized; the structure is simple, parts are few, and the assembling is easy; the internal structure is simplified, and part of the released space can be used for further adding related functional structures such as pressure regulation, filtration and buffering; through a labyrinth loop, dust and impurities are effectively preventedfrom entering the valve; and through flexible sealing formed by the diaphragm, the problem of oil leakage caused by vibration in the driving process is solved.

    本发明涉及呼吸阀领域,公开了膜片式油泵呼吸阀,其包括阀体(1),阀体(1)内设有膜片空腔(2),膜片空腔(2)内安装有膜片(3),膜片(3)将膜片空腔(2)分割为第一腔(201)和第二腔(202),膜片(3)受到第一腔(201)和第二腔(202)间的压差变形并连通第一腔(201)和第二腔(202)。本发明通过膜片的变形,实现呼吸阀应有的功能;结构简单,零件少,易于组装;简化了内部结构,释放出部分空间可用于进一步新增诸如调压,过滤,缓冲等相关功能结构;通过迷宫形回路,有效阻止灰尘杂质进入阀内;通过膜片形成的柔性密封,解决行车过程中因震动发生的漏油问题。
