摘要： A master cylinder having a main piston (12) located in a main bore (110) of a body (11) to define a working chamber (13), a reaction piston (3) located in a stepped bore (120) of the main piston (12) to define a reaction chamber (4) with components to providing a hydraulic reaction to a pneumatic booster. The main piston (12) slides in the main bore (110) in response to a boost force to develop an actuation force while the reaction piston (3) slides in the stepped bore (120) in response as a function of the actuation force. A first shut-off seat (41) is located on a front face of the reaction piston (3) is located in the reaction chamber (4) while a second shut-off seat (42) located in the reaction chamber (4) is mounted on a seat support (7) carried by the main piston (12). A first spring (51) urges the reaction piston (3) in a direction most likely to move the first shut-off seat (41) away from the second shut-off seat (42). In response to a rapidly applied actuation force, the first shut-off seat (41) moves toward the second shut-off seat (42) to prevent the communication of the reaction force to the reaction piston (3).

摘要： The invention relates to a brake booster with a short operating travel, in which the three-way valve comprises a mobile valve seat borne by a sleeve (54). The movement of this sleeve is controlled by the piston. According to the invention, there is an elastic device (70) applying force to the sleeve (54) in the direction of the front of the booster, and tending to move this sleeve forward with respect to the pneumatic piston (12). In addition, there is a device for transmitting the pressure of the master cylinder (120) to the sleeve (54) and that tends to apply a rearward force to the sleeve (54).

摘要： A master cylinder having a body (10) with a bore (12) therein in which slides at least a primary piston (20). The primary piston (20) has a compensation passage (58), which in a position of rest, places a pressure chamber (24) in communication with a reservoir (14). The communication between interrupted upon actuation of the master cylinder by a control rod (18) acting on a second piston (48) sliding in the bore (12). A first compression spring (28) and a second compression spring (42) urge the primary piston (20) and second spring (16) toward a rear position of rest. The preload force of the first compression spring (28) exceeding that of the second compression spring (16) such that the second piston (48) is the first to move in response to a force applied to the control rod (18). The rear position of rest for the primary piston (200 and second piston (48) is defined by a same stop (36) which is integral with the body (10) of the master cylinder.

摘要： A braking device, for a motor vehicle, comprising: a master cylinder (2), a primary piston (3) mounted to slide in the master cylinder, a manual-control member (4), a booster coupled to the manual-control member, an emergency assist valve (VA) comprising a reaction piston (17a) and a rapid piston (17b), and a ratio control (T) actuated by a plunger distributor (10) driven by the manual-control member (4). The reaction piston (17a) and the rapid piston (17b) form one and the same stepped piston (17) having a part (17a) of large cross section and a part (17b) of small cross section, the large-section part (17a) determining, with a first bore (18) of the primary piston (3), a variable-volume annular chamber (27). A separation/communication assembly (28, 29, 30), controlled by the displacement of the stepped piston (17), is designed so that the pressure of the liquid is exerted effectively on the large cross section (17a) of the stepped piston when the stepped piston occupies a position of rest or is to the rear of the position of rest, and on only the small cross section (17b) when the stepped piston is displaced forward relative to the main piston under emergency braking.
