Abstract
The invention relates to an integrated pressure amplification and modulation system for a hydraulic brake circuit, comprising at least one master cylinder (10), a hydraulic motor, a source of fluid under high pressure (48) and a reservoir of fluid under low pressure (14), a computer-controlled solenoid (32) modulating by way of a magnetic core (30) the position of a slide (22) which slides in a bore (20). According to the invention, the fluid under pressure coming from the master cylinder (10) is applied to one face (24) of the slide (22), the other face of which bears on the magnetic core (30l ) and receives the force exerted by a spring (34) for return to rest. A reaction chamber (40) formed in the slide (22) is connected permanently to the hydraulic motor (38), and the hydraulic motor (38) is connected either to the reservoir (14) or to the source of fluid under pressure (48), depending on the position of the slide (22).
