The invention provides an integrated pump valve assembly and a pneumatic adjusting system for an automobile seat. The integrated pump valve assembly comprises a pump body part and at least one valve group part; an air channel silencing connecting part is arranged between the pump body part and the valve group part; the air channel silencing connecting part comprises a labyrinth type silencing cavity; at least one air inlet and at least one air outlet are formed in the labyrinth type silencing cavity; a grating bending air path is arranged between the air inlet and the air outlet; the air inlet is in butt joint with an air output port of the pump body part; and the air outlet is in butt joint with the air inlet port of the valve group part. According to the technical scheme provided by the embodiment of the invention, the silencing cavity is formed between the pump body part and the valve group part, the air path is bent through the grating on the silencing cavity, distributed air resistance speed reduction is carried out on the output air flow of the pump body part, and the function of reducing noise is achieved. Compared with the prior art, the pneumatic seat is more suitable for pneumatic massage, pneumatic waist support, pneumatic seat posture adjustment and pneumatic seat hardness adjustment in the field of vehicle seats.

    本申请提供一种一体式泵阀总成及汽车座椅用气动调节系统,其中一体式泵阀总成包括泵体部和至少一个阀组部,泵体部和阀组部之间设有气路消音连接部;气路消音连接部包括迷宫式消音腔体;迷宫式消音腔体上设有至少一个进气口和至少一个出气口;进气口与出气口之间设有格栅折曲气路;进气口与泵体部的输出气端口对接;出气口与阀组部的进气端口对接。根据本申请实施例提供的技术方案,通过在泵体部与阀组部之间设置消音腔体,利用消音腔体上的格栅折曲气路,将泵体部的输出气流进行分布式气阻减速,实现降低噪音的功能。相较于现有技术,更适用于车辆座椅领域的气动按摩、气动腰托支撑、气动座椅姿态调节、气动座椅软硬度调节。
