<p>A shock absorber for a washing machine includes a cylinder (1), a plunger (2) carried by a shank (3) forming a double chamber within the cylinder (1), and the double chamber being sealed at the outlet of the shank with the aid of a two-lip gasket (7), characterised in that the gasket (7) is linked in an immovable manner to the cylinder inlet so that, apart from sealing the shank at its outlet, it ensures that from a stable situation corresponding to when the shank is inserted to a maximum inside the cylinder, and as the shank emerges and the effective volumetric capacity of the double chamber increases, a gradual depression or vacuum is created acting as recovery means urging the shank to return to the stable situation.</p> |
