摘要:
This invention relates to a master cylinder of the so-called “penetration” type, in which a cup (3), which is fitted inside a groove (11) of the master cylinder, bears on the wall (20) of a piston (2) in a sealing manner, and in which such wall (20) is provided with main resupply ports (51).According to the invention, the wall (20) of the piston (2) also comprises secondary resupply ports (52) having a smaller size than that of the main resupply ports (51) and disposed farther from the bottom part (33) of the cup (3), and achieving an outstanding static resupply of the master cylinder with brake fluid, with a reduced dynamic dead stroke.

摘要:
The invention relates to a brake fluid reservoir comprising at least two lateral mounting lugs (10, 11) designed to be placed either side of a central mounting lug (20) of a brake master cylinder. Collinear holes (12, 13, 21) traverse these lugs and are designed to receive a mounting pin (3). The said lugs include at least one device for the axial immobilization of the mounting pin (3).
摘要:
An arrangement (10) for the connection of a brake fluid supply reservoir (12) to a longitudinal brake master cylinder (14) of a motor vehicle, in which at least one lower supply pipe (16) connected to the reservoir is received in a complementary supply bore (18) of the master cylinder (14) and in which vertical immobilization structure (20) is interposed between the pipe (16) and the master cylinder (14). The arrangement is by an intermediate baseplate (22) that is connected to the reservoir (12) by at least one nozzle (24) including the supply pipe (16) and that is lowered vertically onto the master cylinder (14) and then immobilized on the master cylinder (14) by way of vertical immobilization structure (20) that directly snap-fastens to the master cylinder (14) to allow rapid attachment of the pipe (16) to the master cylinder (14).

摘要:
This invention relates to a master cylinder (10), inside a bore (14) of which two axial primary and secondary pistons (16, 18), are slidingly fitted, and in which at least one sealing means (48, 50) is disposed in contact with each piston, defining a supply chamber (56, 60) and a pressure chamber (58, 62). Each piston (16, 18) comprises a bore (78, 80), open in the direction of the front pressure chamber (58, 62), and the piston (18) comprises a valve-forming through-hole (88), opening into its periphery and into its bore (80), in order to isolate the front pressure chamber when it passes beyond the sealing means so as to produce a braking pressure, characterised in that the front pressure chamber (62) associated with at least one piston (18) comprises at least one tubular cylindrical element (90) extending axially outside the piston (18) and rearwards of the sealing means (50) for the obturation of the through-hole (88) according to a reduced stroke (Cm2).
摘要:
A ball-joint connection for a braking system comprising a male element (2) and a female element (4). A first end (14) of the male element (2) includes pegs (30,30′) that are automatically radially extracted when the first end (14) is mounted in a female element (4) defined by a housing (16). The pegs (30,30′) collaborate with the interior surface (18) of the housing (16,66) to define a ball-joint connection between the male element (2) and the female element (4). The female element (4) being formed on one end of a piston (66) of for a master cylinder and the male element (2) forms the actuating rod of the master cylinder.
摘要:
A master cylinder (32) in a vehicle hydraulic braking installation uhydraulic-fluid supply device for actuating wheel brake cylinders (20). The master cylinder (32) being isolated from the wheel brake cylinders (20) by at least one shut-off valve (30). The master cylinder (32) being associated with a simulator (46) having a piston (50) located in a simulator chamber (56). The piston (50) being subjected to fluid pressure of brake fluid from the master cylinder (32) and an elastic element (52). The master cylinder (32) being of the having a primary piston (44) and a secondary piston (60) slidably located in a bore (45) of a housing (48). Bore (45) has a peripheral groove (72) which is associated with a land (68) on the secondary piston (60) to allow communication with the simulator chamber (56) when the master cylinder (32) is in a positon of rest. A sealing element (70) carried by the secondary piston (60) engages the housing when the secondary piston moves to interrupt communicaton between the bore (45) and simulator chamber (56) to thereafter simulate brake actuation travel.
