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...

A hydraulic fluid container (10) for a vehicle hydraulic brake system comprises at least one connecting sleeve (14), in which a valve member (20) is displaceably guided. The valve member (20) in a first position, into which it is spring-biased, blocks the connecting sleeve (14) and in a second position clears the connecting sleeve (14). On its circumferential surface the valve member (20) is provided with at least one radially elastic detent element (32; 32'). The connecting sleeve (14) in its i...

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).

A master cylinder includes a cylinder body and primary and secondary pistons slidably received in the cylinder body, thereby defining first and second pressure chambers in the cylinder body. The first and second pressure chambers communicate with a reservoir through first and second fluid passages, respectively. During automatic brake control such as traction control or vehicle stability control, hydraulic fluid is drawn from the reservoir through the first and second pressure chambers. A thrott...

A supply device for a braking system, comprising at least one reservoir (2) for supplying a master cylinder, and a rigid support (4) for the reservoir (2), characterized in that the reservoir (2) and the fastening support (4) comprise male (26) and female (28) elements collaborating with one another, and in that elastic sleeves (30) are inserted between the male elements (26) and the female elements (28).

A throttle valve mechanism having a throttle function of throttling the flow of working fluid from a pressure delivering chamber to a reservoir at the operation time of the piston of a master cylinder, a valve function of allowing the working fluid to flow from the reservoir to the pressure delivering chamber by opening the valve at the return time of the piston, and a relief valve function of allowing a large quantity of working fluid to flow from the pressure delivering chamber to the reservoi...

A master cylinder device for a brake comprise a master cylinder body having a cylinder bore, a reserve tank provided integrally with the master cylinder body so as to have a fluid reserving portion for feeding hydraulic fluid for the brake, a fluid passing port provided in the fluid reserving portion of the reserve tank, the fluid passing port having an opening area smaller than an opening cross-sectional area of the fluid reserving portion, and a communicating passage connecting the fluid passi...

A master cylinder and booster device for a motor vehicle braking system, in which the master cylinder (10) and the booster (12) are assembled to form a one-piece entity comprising a small reservoir (20) of brake fluid mounted on the master cylinder (10) and connected by a flexible duct (22) to a separate brake fluid reservoir (24) secured temporarily to the entity (10 12) for the purposes of delivering it to a motor vehicle manufacturer.

An annular inward turned flange and a plurality of ribs are integrally molded on an inner peripheral surface of an cylindrical portion formed at an upper portion of a reservoir for a master cylinder. The ribs extend from a lower surface of the flange and are disposed in a distributed manner in a circumferential direction of the flange. An annular flat surface area is formed on an upper surface of the flange, and a tip end of a working oil filler is placed into close contact with the annular flat...

A fluid injection port 10 is formed in the upper portion of a reservoir 5 at the front side of a vehicle. A first union hole 13 and a second union hole 14 are formed in a bottom wall 6g, and a level detector 15 is provided in a fluid chamber 4. The fluid chamber 4 is divided by partition walls 6i and 6j into a first fluid chamber 4a, a second fluid chamber 4b and a third fluid chamber 4c. The fluid injection port 10 communicates with the first fluid chamber 4a, the first union hole 13 communicat...
