    摘要： The invention relates to an assisted hydraulic braking system comprising a brake pedal (10) connected to an actuating rod (46), a pneumatic brake booster (14) comprising a front vacuum chamber (102) and a rear working chamber (104) separated by a movable deformable partition acting on a push rod, a single master cylinder (16) the piston of which is acted by the push rod, a mechanism (12) for controlling the booster (14), comprising a shutter mechanism (34) putting a first chamber (26) selectively in communication with a second chamber (30) or with the atmosphere responsive to an actuating of the brake pedal (10), a first pipeline (110) putting the first chamber (26) of the control mechanism (12) in communication with the working chamber (104) of the booster (14), a second pipeline (112) putting the second chamber (30) of the control mechanism (12) in communication with the vacuum chamber (102) of the booster (14), a second master cylinder (74) the outlets of which are connected to at least one wheel brake, the second master cylinder (74) being subjected to the actuating pressure transmitted by the actuating rod (46) and increased by the boosting pressure generated by the single master cylinder (16).

    摘要： A power assisted pedal assembly comprises a brake pedal pivotally connected at one end to a lever which is pivotal about a fixed point, the brake pedal having a connection intermediate its ends with an actuating member of a master cylinder to apply an operating force to the actuating member, and a power assistor operable in response to movement of the brake pedal to apply an assisting force to the brake pedal. The power assistor has a force-transmitting member which is separate from the actuating member and which is in force-transmitting engagement with the lever on or close to the line of action of the force applied to the actuating member by the brake pedal. The brake pedal and the lever pivot about the fixed point when the power assistor is operative and the pedal pivots about a point intermediate the fixed point and the connection between the lever and the actuating member upon failure of the power assistor.
