The double-acting shock absorber producing the throttling of a fluid flowing through a constricted passage for damping out a movement in constructed, in combination of, a fixed piston (2) and a fixed cylinder (3) cooperating both with a movable member (4). This movable member has two axially aligned portions, that is, an upper portion (5) and a lower portion (6), the upper portion having a cylindrical cavity in which the fixed piston (2) is slidably fitted, and the lower portion having the configuration of a piston slidably engaged in the fixed cylinder.
