Abstract

PROBLEM TO BE SOLVED: To eliminate variation of the quantity of fluid flowing out of each branch pipe to substantially equalize the quantities of fluid flowing out of the branch pipes and miniatulize the distributor and facilitate the cleaning by branching the front end of a fluid inflow pipe into two branches and substantially equalizing the total sectional area of the insides of the branch pipes to the sectional area of the inside of the fluid inflow pipe. SOLUTION: A fluid inflow pipe (a) is a hollowed pipe for force-feeding a fluid and the material is preferably metal or plastic. The inner diameter is, not specifically limited, preferably about 2.8-10 cm. The shape of the pipe (a) may be a circular cylinder or a square cylinder. The front end is branched into two pipes b1, b2. The branch pipes b1, b2 may be made of the same material and has the same shape as those of the inflow pipe (a). The inner diameter is, not specifically limited, preferably about 2-7 cm. The sectional areas of the inside are equal to each other and it is preferable that the total area is equal to the sectional area of the inflow pipe (a). The sectional area is the area of the inner diametral part of the section perpendicular to the force feeding direction of the fluid.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid distributor in which fluids such as liquids, gases, and powders are pressure-fed through hollow tubes and evenly distributed.

[0002]

2. Description of the Related Art A fluid such as a paint is pumped and distributed to two or more for painting or the like. Specifically, the paint is filled in a tank, and the paint is discharged from a plurality of outlets provided in the tank and distributed. However, this method has a defect that the amount of outflow varies because the pressure applied to the paint inside the tank is not uniform. Further, the dispersion is reduced to some extent by increasing the inner volume of the tank and filling it in a large amount. However, a large amount of time is required for cleaning the inside of the tank when replacing the contents, and the loss of paint is further increased.
