Abstract
This valve comprises a tubular body (66) containing a hollow slide (68) mounted axially slidably in a sleeve (69), itself sliding in the body (66) along the axis (X--X) of the valve, a spring bearing on the body and pushing the slide (68) up against an annular end (73) of the sleeve (69), normally held by means of its opposite end (79) up against a cover (82) for closing the body (66) on the opposite side to its central orifice (67); the cover (82) and the sleeve (69) have radial ports (88, 81), the body (66) being contained in a tubular casing (34) having conduits (92, 96), fluid passages (89, 93, 94, 95, 40) also being provided to allow the valve to open in both directions as a result of the hydraulic pressure. This valve makes it possible to peak-limit the surplus hydraulic flow of a shock absorber (31), thus preventing the tailgating of the vehicle body at means vertical speeds under compression and making it possible under expansion, after the vehicle has passed over a hump, for the wheel to make contact with the ground again before the vehicle body.
