Các nghĩa

máy giặt
A flat piece of material, often of metal and often an annulus, placed beneath a nut or at some joint, to distribute pressure, alleviate friction, provide directionally differentiated friction (e.g. making the nut turn counter-clockwise only with difficulty), or prevent leakage.
To ensure that the stays are steamtight, a nut is then screwed tight up to copper washers inside and out.
