Laundry washing/drying machine

摘要

Laundry washing/drying machine (1) comprising a casing (2) and at least one revolving element (6; 21) which is fixed in axially rotating manner inside the machine casing (2) for rotating about a given rotation axis (L, R); the revolving element (6, 21) being provided with a supporting shaft (10, 22) which projects from the revolving element main body (13, 14) coaxial to the rotation axis (L, R), and is fitted in axially rotating manner into a corresponding supporting hub (11, 23) present in the machine casing (2); the supporting hub (11, 23) having a central hole and the supporting shaft (10, 21) engaging the central hole of the supporting hub (11, 23) so as to form, inside the latter, a cylindrical interspace (14) which is filled with a magnetic-field-responsive fluid having lubricant properties; the supporting hub (11, 23) also having a magnetic-field source (16, 26) capable of generating a magnetic field which restrains the magnetic-field-responsive fluid inside the cylindrical interspace (14).
