Title: VIBRATION DAMPER AND LAUNDRY MACHINE COMPRISING SAME
Abstract:
A vibration damper comprises: a cylinder (2), having an inner cavity; and a damping block (3), slidably disposed in the inner cavity and dividing the inner cavity into a first chamber (21) and a second chamber (22). The vibration damper is characterized in that a third chamber (31) is disposed inside the damping block (3), damping holes (34) are provided on the damping block (3), the first chamber (21) and/or the third chamber (31) are filled with fluid, and when the damping block (3) slides relative to the cylinder (2), the fluid flows between the first chamber (21) and the third chamber (31) through the damping holes. The vibration damper can self-adaptively adjust the damping according to the vibration amplitude and enables the movement of a damping block (3) in a cylinder (2) through static pressure holes, thus achieving the effect of a static pressure bearing.
