    摘要: The shock absorber comprises a working cylinder (3) in which a piston (1) integral with a rod (2) defines two chambers (7, 8). In accordance with the invention, a rotary solenoid valve is placed in an end piece closing the working cylinder so as to control the circulation of the damping liquid between one chamber (7) and a reservoir (10). The solenoid valve comprises a passage (18, 22, 19) for the liquid between this cheer and this reservoir and closing devices (21, 21', 21", 21"') for the selective throttling of the passage. The closing devices are integral with a rotor (27) mounted on a bearing (33), opposite a stator (26) forming part of a magnetic circuit (25, 26, 27) excited by an electric coil (24). Air gaps extending parallel to the axis of rotation of the rotor (27) are formed between the stator and the rotor. Feeding the coil (24) brings about the rotation of the rotor (27) and the closing devices ( 21) integral with the latter, in order to cause the throttling of the passage to vary.
