関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for filling a master cylinder of, for example, an automobile or a motorcycle with brake fluid.

パロック現象を起こすおそれがある。2. Description of the Related Art Glycol and ethylene glycol are used as brake fluid for vehicles. Since these glycols and ethylene glycol have hygroscopicity, they may absorb moisture over time. When water is absorbed, the boiling point of the brake fluid decreases, and the heat generated when the brake is applied evaporates the water in the brake fluid, which may cause a vapor lock phenomenon.

されている。[0003] Japanese Patent Application Laid-Open No. 56-75257 discloses that a crystalline aluminosilicate (zeolite) is placed in a reservoir tank attached to a master cylinder, and water molecules having a small molecular diameter are formed into fine pores of the crystalline aluminosilicate. There has been proposed a method of selectively removing only water molecules by adsorbing in water.

いる。[0004] On the other hand, there is a possibility that moisture may be absorbed in the step of filling the brake fluid. Therefore, conventionally, J
The boiling point of the brake fluid is measured by the boiling point test method (Karl Fischer method) specified in IS, and when the boiling point of the brake fluid falls below a predetermined value, it is determined that the water contains an allowable amount of moisture or more. , To stop filling.

にブレーキ液中の水分を除去することは行っていない。As described above, in the conventional brake fluid filling process, the amount of water absorbed in the brake fluid is measured, but the brake fluid is positively measured. We did not remove water.

When the crystalline aluminosilicate is put in the reservoir tank, there is no problem if it takes some time, but it cannot be applied to the step of filling the brake fluid. In addition, it is difficult to determine that the adsorption capacity of the crystalline aluminosilicate has become saturated, and the crystalline aluminosilicate can be replaced more frequently than necessary. Will continue.
