    Abstract: The brake system comprises two hydraulic sub-circuits, each connecting a driving wheel and a free wheel to a working chamber of a master cylinder (1) connected to a general reservoir (20) of fluid under low pressure, and including a wheel anti-lock braking device comprising a three-way solenoid valve (51, 52, 53, 54) normally opening communication between an inlet of fluid under pressure and the brake motor, while, in the expansion phase of the anti-lock device, it closes this communication and connects the brake motor to a reservoir (21, 22) of fluid under low pressure to each sub-circuit. The device comprises a differential valve slide consisting of a valve of which one face receives the pressure prevailing in the associated brake motor (31, 32, 33, 34) and the other that as generated by a pump (45, 46) and, at rest, putting in communication the working chamber of the master cylinder (1) and the inlet of fluid under pressure. The valve slide isolates the brake motor from the working chamber of the master cylinder during the operation of the pump (45, 46). A differential pressure/underpressure valve (76, 77) associated with each free wheel closes, at rest, communication between the working chamber of the master cylinder and the suction inlet of the pump (45, 46), and opens this communication in the event of underpressure in the corresponding brake motor (31, 33) only when there is no pressure generated by the master cylinder (1).

    Abstract: The invention discloses a power-steering mechanism for an automotive vehicle, having a double acting actuator with two pressure chambers separated by an actuator piston. The actuator is connected both to the chassis of the vehicle and to a linkage associated with the direction controlling wheels of the vehicle. The pressure in the actuator chambers are controlled by a distributing valve operated by the steering wheel moved in either direction from a central, idle position. A reaction device adapted to create a return force biasing the steering wheel into its central position includes a circular cam eccentrically mounted on the rotating shaft of steering wheel and subjected to a thrust transmitted by a tappet. The tappet is projecting into a closed compartment to engage a reaction piston submitted to the pressure prevailing in a fluid accumulator. Two plungers are slidably mounted in the compartment and are submitted to the pressure prevailing in the actuator chambers. Finally stops are provided to limit motions of the plungers out of the closed compartment.

    Abstract: A pressure-regulating solenoid valve (100) for a hydraulic circuit for a braking system of a motor vehicle having wheel antilock structure. The hydraulic circuit has at least one pressurized fluid generator (300) connected to a pressure receiver (200) and to a reservoir (400) for retaining fluid at a low pressure. The solenoid valve (100) has an electrical coil (10) which interacts with two pole pieces (12,14), a sleeve structure (28,30) forming a magnetic body (26) which moves under the effect of an actuation force (O) generated by a magnetic field created by the electrical coil (10) and a distributor element (34). The distributor element (34) interacts with the sleeve structure (28,30) in order to command communication between a duct (98) connected to the pressure receiver (200) and a duct (94) connected to the reservoir (400) or a duct (96) connected to the pressure receiver (200). The solenoid valve (100) has at least one reaction chamber (80) which is permanently in communication with pressure chamber (200). The solenoid valve (100) reacts to a reaction force which is added to an actuation force (O) generated by the coil (10) and counter to a force (F) generated by a preloaded elastic means (46,85) on the movable body (26).
