<p>Shock absorber for the oscillations of the unit tub-drum in household clothes washing machines. Shock absorber comprising a tubular housing (28) and a rod (33) reciprocatingly sliding therein, which are made with outlines of polygonal shape, having sides of number and form equal to each other, so as to coincide reciprocally at any shock absorber operative state, to allow the friction means (56) fixed to the rod (33) to exert always steady and evenly distributed braking actions on the tubular housing (28). The shock absorber is also made with removable and self-lubricating structure.</p> |
