Title:
DAMPER
Document Type and Number:
Japanese Patent JPS54125370
Kind Code:
A
Abstract:
PURPOSE:To automatically control a damping force depending on the variation in the load on a damper, by attaching a frictional force control member to a part of the inside surface of a cylinder. CONSTITUTION:When the damper 6 is applied to a fully automatic washer, a heavy load acts on the damper and a piston 3 is displaced to a point A against a coiled spring 2 during draining and dehydration. At the point A, the width of the frictional force control member 24 is large and the damping force is strong. After the dehydration, the load decreases and the piston 3 is moved to a position B by the restoring force of the coiled spring 2. At the point B, the width of the frictional force control member 24 is small and the damping force is weak.
