Patent ID: 8807306

Claim:
A friction damper for a washing machine with a drum and a spinning cycle, said friction damper comprising a movable piston rod which is arranged in a housing ( 1 ) parallel to the longitudinal axis of the housing and is guided out of the housing ( 1 ), the movable piston rod comprising a friction element, wherein the housing ( 1 ) comprises at least one plastic element ( 3 ) and at least one heat conducting metal element ( 2 ), with the at least one heat conducting metal element having at least one metal having a heat conductivity of at least 150 watts per meter and Kelvin (150 W/(m*K)) and at least one contact surface in direct contact with the at least one plastic element, and wherein the at least one contact surface is adjacent to and directly abutting against the friction element of the movable piston rod, wherein frictional damping is provided by relative motion between the friction element of the movable piston rod and the at least one contact surface, and wherein heat generated in the contact surface is absorbed or conducted away by the heat conducting metal and not substantially absorbed by the at least one plastic element.
