DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reservoir for storing a liquid such as oil, and more particularly to a reservoir used when a liquid is used for a plurality of purposes.

[0002]

2. Description of the Related Art A brake reservoir stores brake fluid. In recent years, it has been considered to use the brake fluid for another purpose such as traction. For example, in the technique disclosed in Japanese Patent Application Laid-Open No. 63-28782, a technique is disclosed in which a brake fluid is directly suctioned from a reservoir by a pump without passing through a master cylinder and is applied to a wheel cylinder. As described above, a fluid reservoir for another system different from the original system may be set in the reservoir.

[0003]

In the prior art, foreign matter such as abrasion powder from another system may enter the reservoir. To prevent this, the interior of the reservoir is separated into two chambers and separated. It is conceivable to arrange a strainer in one room for use. When the inside of the reservoir body is separated by a partition for another system, there is no way for the air accumulated at the top of the one chamber for the another system to escape when fluid is injected into the reservoir, and the liquid level in one chamber for the other system is adjusted. Can not.

Accordingly, an object of the present invention is to form a reservoir having a simple structure so that the reservoir can be used for multiple purposes and the fluid level of the fluid can be adjusted when the fluid is injected.

[0005]

Means for Solving the Problems The means used in the present invention for solving the above-mentioned problems has a separating wall dividing the inside into two chambers, and is a hollow member formed by combining an upper body and a lower body. A body, a reservoir that is sandwiched between the upper body and the lower body, is disposed in one chamber of the body, and has a strainer that partitions the one chamber up and down and filters the space between the top and bottom; A slit opened across is provided on the separation wall, and a fitting portion sandwiched between the slits is provided on the strainer.When the slit sandwiches the fitting portion, the slit leaves a passage for ventilation at an upper portion and a liquid is provided on the lower body. Has a passage for distribution.

[0006]

According to the above-mentioned means, two chambers can be formed simply by inserting the fitting portion of the strainer into the slit provided in the upper and / or lower body and assembling the upper body and the lower body. The strainer is provided in a room for another system and filters fluid returning from the other system. The lower part of the chamber for another system can freely communicate with the other chamber by the lower part of the slit. In addition, at the time of fluid injection, air accumulated in the upper part of the chamber for another system can freely flow to and from the other chamber through the upper part of the slit. Surface adjustment is possible.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. This embodiment is an example in which a traction chamber for traction control is provided for a reservoir that supplies brake fluid to a master cylinder of a vehicle.

In FIG. 1, a reservoir body 10 is formed by combining an upper body 10a and a lower body 10b. A space is formed inside the reservoir body 10.
Further, inside the reservoir body 10, there is formed a separation wall 10c which divides this space into two right and left parts. Further, the separation wall 10c
A strainer 11 having a filtration unit 12 is disposed in a chamber (traction chamber) on the right side of FIG. This separation wall 1
Oc and the strainer 11, the interior of the reservoir body 10 has a first chamber 13 on the left side of the separation wall 10c, a second chamber 14 on the upper right side of the separation wall 10c, and a lower chamber on the right side of the separation wall 10c in the drawing. It is partitioned into the third chamber 15. The second chamber 14 is provided with an input port 10d for receiving return oil for traction control. The third chamber 15 has an output port 10e for outputting oil to the traction control unit.
Is provided. As shown in FIG. 2, the strainer 11 divides the second chamber and the third chamber by a filtration unit 12. The filtration unit 12 filters the oil returned to the second chamber 14 and filters the oil returned to the third chamber 15.
Send to

As shown in FIG. 3, slits 10f and 10g are provided in a separation wall 10c provided on the upper body 10a and the lower body 10b. This slit 10
The fitting portion 11a of the strainer 11 is fitted into f and 10g. The upper slit 10f of the fitting portion 11a serves as an air passage, and the lower slit 10g of the fitting portion 11a serves as an oil passage.

When oil is introduced from the inlet 10h, the oil
The chamber 13 enters the second traction chamber 15 through the slit 10g. Since the upper part of the traction chamber communicates with the first chamber 13 through the slit 10f, the air flows to the first chamber 13 through the slit 10f, and the liquid levels of the first chamber and the traction chamber become the same.

[0011]

As described above, in the present invention, the fluid level can be adjusted without increasing the number of parts. Also, the mold structure of the body can be simplified.
