た液供給部とを備えたものが知られている。 Conventionally, this type of device includes a main body in which a side wall and an upper and lower wall form an internal space whose length in the vertical direction is larger than the length in the horizontal direction; A device is known that includes a partition wall that partitions into two liquid chambers, and a liquid supply section that is connected to each of the liquid chambers.

の問題を助長する。 However, in such conventional devices, since a relatively long wall is provided along the vertical length in the partition portion, when forming the reservoir from a synthetic resin material by molding, the mold There are problems in that the production becomes complicated or the durability of the mold deteriorates. In other words, when creating such a partition wall with a long vertical length in the partition part, since it is provided parallel to the side wall with a relatively small interval, a part of the mold located between the partition wall and the side wall is The usage conditions are more severe than that of other parts, resulting in poor durability. In addition, in the conventional device, in order to sufficiently restrict liquid movement, the combined shape of all the partition walls of the partition portion is extremely complicated, and such complexity further exacerbates the above-mentioned problem.

にしたものであり、これにより以下のような効果
を奏するものである。 The present invention has been developed in view of the above problems, and it is possible to sufficiently restrict the movement of liquid between liquid chambers even if the combined shape of the partition walls is simplified, and even if there is movement of liquid within the liquid chamber, it is possible to prevent the liquid from flowing into the liquid supply section. The purpose is to provide a reservoir for a master cylinder which is able to prevent air intrusion, and to achieve this purpose, the lower wall is provided with an upwardly extending shoulder adjacent to the liquid supply of each of the liquid chambers. a bulging part is formed with a part interposed therebetween, and the partition wall part is continuous between the side walls so as to vertically divide the internal space into three liquid chambers, and the partition wall part is continuous between the shoulder parts of the bulging part in the lateral direction. two flat partition walls formed in the same direction, a flat plate-shaped auxiliary partition wall formed continuously in the vertical direction between both partition walls, two auxiliary chambers formed between both partition walls by these auxiliary partition walls, and one partition wall. one passage provided in the partition wall to communicate between one auxiliary chamber and one liquid chamber; and one passage provided in the other partition wall at a position shifted from said one passage when viewed from the vertical direction, and connecting the other auxiliary chamber and the other liquid chamber. and a passage provided on the vertical center side of the auxiliary partition wall that connects both auxiliary chambers, thereby producing the following effects.
隔壁間に連続して横方向に形成した２つの隔
壁により、内部空間が３つに区分されるため、
各液室の縦方向長さを短かくでき、減速度、加
速度の作用で作動液が移動しようとしても各液
室内での移動を小さくすることができる。 The internal space is divided into three parts by two partition walls formed laterally in succession between the partition walls.
The length in the vertical direction of each liquid chamber can be shortened, and even if the hydraulic fluid tries to move due to deceleration or acceleration, the movement within each liquid chamber can be reduced.
隔壁間に縦方向に延びる補助隔壁は、２つの
補助室を区分しかつ中央部側に形成した通路で
両補助室を連通しているので、縦方向の液移動

限されることにより、液室間での液移動を充分
制限する。そして、液室と補助室とを連絡する
２つの通路が、、縦方向からみてずれた位置に
あり、液移動をより効果的に制限できる。 The auxiliary partition wall extending vertically between the partition walls separates the two auxiliary chambers and communicates the two auxiliary chambers with a passage formed on the center side, so even if vertical liquid movement occurs, the auxiliary space is immediately removed. Since each auxiliary chamber independently communicates with the liquid chamber without allowing liquid movement between the auxiliary chambers, even if liquid moves from one auxiliary chamber to the other, the liquid between the auxiliary chambers will not flow. By restricting movement, liquid movement between liquid chambers is sufficiently restricted. The two passages connecting the liquid chamber and the auxiliary chamber are located at different positions when viewed in the vertical direction, so that liquid movement can be more effectively restricted.
こうした液移動の制限を、平板状の２つの隔

部分に比して厳しい条件とすることもなく、金
型の耐久性を向上できる。 This restriction of liquid movement can be achieved by forming two flat plate-shaped partition walls and a flat plate-shaped auxiliary partition wall, and together with the fact that each partition wall is flat, the partition structure can be simplified and synthetic resin material can be used. When molding from a mold, the shape of the mold is simplified to facilitate production, and the distance between the partition walls does not need to be small, and the length of the partition walls does not need to be extended in the vertical direction, so it can be relatively short. Therefore, the durability of the mold can be improved without subjecting a part of the mold to harsher conditions than other parts in order to form each partition wall.

る。 The partition wall portion is formed on the upper surface side of a bulge formed through a shoulder portion extending upward in proximity to the liquid supply portion, and the bulge portion reduces the amount of remaining liquid in the liquid chamber. Even if the degree of inclination of the liquid level becomes large when the liquid level is decreasing, air can be prevented from entering the liquid supply section, and air will not be supplied into the master cylinder.
Even if an attempt is made to move beyond the shoulder of the bulge, the movement is blocked by the partition wall on the bulge, making it possible to restrict liquid movement more effectively.

2 and 13 are formed, and the bulged portion 1
A vertical rim 14 and a plurality of horizontal rims 15 are provided on the lower surface side of 1 for reinforcement.
A plurality of attachment holes 16 are formed in the rim 14 for attaching the entire reservoir 1 to the cylinder body of a tandem master cylinder (not shown) via bolts or the like. Each of the liquid supply parts 12 and 13 has stepped cylindrical parts 18 and 19 whose diameters gradually become smaller toward the bottom.
The inner holes 20 and 21 communicate the inside of the reservoir 1 and the inside of a liquid connection part (not shown) of the cylinder body.

補助室２７，２８に区画されている。 The internal space 8 is divided into three chambers by a pair of horizontally parallel partition walls 22 and 23 extending from the bulge 11 to the upper wall 6 and sandwiching the step 10. The chamber on the left side is a liquid chamber 24 communicating with the inner hole 20 of the liquid supply section 12, and the chamber on the left side is a liquid chamber 25 communicating with the inner hole of the liquid supply section 13. The chamber between the partition walls 22 and 23 is located at a position slightly offset from the center in the vertical direction.
It is further divided into two auxiliary chambers 27 and 28 by an auxiliary partition wall 26 formed therebetween.

６，７間に各々設けてある。 One of the auxiliary chambers 27 is located near the side wall 5 of the partition wall 23 and communicates with the liquid chamber 25 through a slit 29 formed from the upper wall 6 to the lower wall 7. It communicates with the auxiliary chamber 28 through a similar slit 30 provided in the central portion located on the right side of the section 10. Other auxiliary room 2
8 communicates with one of the auxiliary chambers 27 and also communicates with the liquid chamber 25 through a slit 31 formed at a predetermined height or more in the central portion of the partition wall 22 . The liquid chamber 2 is located in the partition wall 22 with respect to the slit 31.
A pair of longitudinally relatively short protrusions 32, 33 on the 5 side.
The upper and lower walls 6, 7 are sandwiched between the slits 31.
In between, and on the side of the auxiliary chamber 28, there is an auxiliary wall 34 that extends vertically over approximately the same length as the portion of the auxiliary partition wall 26 on the right side of the slit 30.
1 is provided between the upper and lower walls 6 and 7 so as to be sandwiched between the auxiliary partition wall 26 and the auxiliary partition wall 26.

る。 After the reservoir 1 is attached to the master cylinder, a sufficient amount of hydraulic fluid is supplied to the inside, and the cap is attached to cover the opening 9 for practical use. In other words, when the liquid level of the hydraulic fluid is at a high position near the opening 9, even if liquid movement is attempted to occur in both the liquid chambers 24 and 25 due to the deceleration acting in the vertical direction, it is particularly difficult. This should not be a problem. That is, at this time, the liquid chamber 25 is filled with the hydraulic fluid, and the liquid chamber 24 is filled with the hydraulic fluid.
Air only exists in the upper part of the auxiliary chambers 27 and 28 on the right side of the stepped portion 10, and even if the liquid moves from the liquid chamber 24 to the auxiliary chamber 28 side, the auxiliary chamber 27 , 28 side to the liquid chamber 24 side is small, so the amount is small.
他方、空間８内の作動液の量が減少し、その液
面がスリツト３１の高さよりも若干高い位置であ

移動に際しての抵抗が大となる。 The liquid moves from the liquid chamber 24 to the liquid chamber 25. First, the liquid passes between the pair of protrusions 32 and 33, flows into the auxiliary chamber 28 while being narrowed by the slit 31, and flows into the auxiliary chamber 28.
The hydraulic fluid that has flowed into the slit 8 once moves toward the partition wall 23, stops moving, and remains in the auxiliary chamber 28, and then flows into the auxiliary chamber 27 as if overflowing from the slit 30. Slits 2
9 into the liquid chamber 25. That is, in addition to the flow path resistance due to each slit etc., when the liquid moves, the resistance during liquid movement increases because the direction of liquid movement and the actual movement path are perpendicular to each other.
また、逆方向の液移動の際にも、これらの現象
は同等に発生する。 Furthermore, these phenomena occur equally when the liquid moves in the opposite direction.

て確保可能である。 Therefore, in the embodiment described above, it is possible to prevent liquid movement between the two liquid chambers. Furthermore, each liquid chamber 24, 2
The amount of liquid guaranteed in 5 is determined by the height determined by the lower end of the slit 31, the degree of inclination of the liquid surface during liquid movement, and the internal shape of each liquid chamber 24, 25. 24 has a relatively large inner shape, so it can be secured sufficiently, and the liquid chamber 25
Since the slits 29 and 30 are formed so that the working fluid in the auxiliary chambers 27 and 28 can flow into the fluid chamber 25, a sufficient amount of fluid can be secured. In particular, when the liquid moves from the liquid chamber 25 to the liquid chamber 24, a portion of the working liquid in the auxiliary chambers 27, 28 is determined by the right half of the auxiliary partition 26, the partition 22, and the side wall 5. and,
Since the liquid is secured in the portion determined by the auxiliary wall 34, the partition wall 22, and the side wall 5 without flowing into the liquid chamber 24, a sufficient amount can be obtained even if the internal shape of the liquid chamber 25 is small. It is possible to secure the working fluid for the liquid chamber 25.

せるようなことがない。 Furthermore, in the above embodiment, each liquid supply section 12,1
Since the bulging portion 11 is provided in the middle of the shoulder portion 11, even if the degree of inclination of the liquid level increases when the amount of remaining liquid in each liquid chamber 24, 25 decreases, the shoulder portion 11
Since the tubes a and 11b are provided close to the liquid supply sections 12 and 13, it is possible to prevent air from entering the inner holes 20 and 21, thereby preventing air from being supplied into the master cylinder.
更に、リザーバ１の縦方向の長さが、横方向の

間での液移動を小さくできる。 Furthermore, although the length of the reservoir 1 in the vertical direction is relatively larger than the length in the horizontal direction, the inside of the reservoir 1 is
Since a dividing wall is provided, although there is some liquid movement between two adjacent chambers, the liquid movement between each liquid chamber can be reduced.
更に、全隔壁の組合せ形状は、互いに対向する

い条件となることがなく、耐久性が向上する。 Furthermore, the combined shape of all the partition walls has a relatively large gap between the opposing partition walls and a relatively short length in the vertical or horizontal direction, so it is difficult to use one mold for forming each partition. This improves durability as the parts are not subjected to harsher conditions than other parts.
