摘要:
An electro-hydraulic unit (10) in particular for an automotive vehicle anti-locking wheel device, includes two separate parts: an electronic control (13) within which is located particularly an electronic card (14), winding (17) as well as an electric motor (15) provided with a rotor and a stator, the motor being adapted to drive a pump, and a hydraulic unit (11), including the pump and a plurality of valves (12), the whole electronically directed by the control (13), the electro-hydraulic unit being characterized in that it further includes a ferromagnetic circuit (22) common at least partially to the stator and to the winding (17).
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.
