    • A valve device includes a shaft, a valving element, a housing, a bearing part, and a breathing path. The shaft is driven in its axial direction. The valving element is displaced integrally with the shaft. The housing accommodates the valving element. The bearing part is provided for the housing, and includes a sliding hole, in which an end portion of the shaft is inserted and which supports the shaft slidably in the axial direction, thereby limiting a displacement direction of the shaft and the valving element to the axial direction. The breathing path communicates between a bottom part of the sliding hole and an inside of the housing.
    • 阀装置包括轴,阀元件,壳体,轴承部分和呼吸路径。 轴沿其轴向被驱动。 阀元件与轴一体地移动。 外壳容纳阀元件。 所述轴承部设置在所述壳体上,并且包括滑动孔,所述轴的端部插入所述滑动孔中,并且所述滑动孔沿轴向可滑动地支撑所述轴,从而将所述轴和所述阀元件的位移方向限制到 轴向。 呼吸路径在滑动孔的底部和壳体的内部之间连通。
