Abstract
A friction damper, especially for washing machines with a spin cycle, consists of a housing (1) having a substantially circular cylindrical inner wall and a tappet (2) that can be pushed coaxially into the housing, extending at one end out of the housing and at the other end being provided with a friction piston. The friction piston is provided with friction elements pressed elastically against the inner wall of the housing (1), and securing elements (4, 8) are formed on the respective ends of the tappet (2) and housing (1). To attain a considerable reduction in the damping forces once there has been a passage through the critical rpm level, the housing (1) is made of plastic.
