<p>Gas shock-absorber comprising two concentric tubes with an intermediary chamber and valve plug (3, 5), and with a shaft of which the head separates two internal chambers, at which extremity is connected the body to the shock-absorber. The valve plug (3, 5) has two parts (3, 5) in direct contact between each other; the sliding of part (3) in the external tube takes place by means of a seal (2) situated between an upper metal washer (1) and a slot (20) of the part (3). The washer (1) has a central neck (18) which is introduced into the cavity (19) of part (3). The other part (5) of the valve plug has cavities (21) which are intended to reduce its weight. The head of the shaft which separates the internal chambers is made of plastic and presents an upper countersunk part wherein is housed an annular seal; a washer is provided on top of the head and the assembly is riveted. <IMAGE></p> |
