Hydraulic fluid control valve, for a motor vehicle shock absorber, comprising piloted lamination module in the form of a cylinder with a slide valve

摘要

The control valve has fluid inlet (1) and outlet (2) channels with a controlled lamination module (3) between them in the form of a cylinder (4) containing a slide valve (5) making primary (61) and secondary (62) chambers. The control valve has fluid inlet (1) and outlet (2) channels with a controlled lamination module (3) between them in the form of a cylinder (4) containing a slide valve (5) making primary (61) and secondary (62) chambers. The primary chamber is connected to the inlet channel through an orifice (71) formed between a radial shoulder (41) on the cylinder and the outer surface (51) of the slide valve. The valve actuator (9) comprises a chamber (90) with a magnetic cover (91) and a coil (92) creating a variable magnetic field for a moving component (8) and containing a magnetostriction solid (93) in a substantially non-compressible fluid.
