Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a filter used for excess of fine particles in a liquid, for example, excess fuel of an internal combustion engine.

[Prior Art] There are several known devices of this type. However, by incorporating them into a vehicle or the like, a compact and high-performance product has been sought after. As shown in FIG. 3, a container having improved clogging performance without increasing the size of the container has been proposed.

In the container shown in FIG. 3, a peroxidized body having a chrysanthemum-shaped cross-section folded inside the container 11 substantially concentrically with the center of the container.
12 is liquid-sealed at the lower end with an end plate 13 and the upper end is a container 11
It is arranged and fixed to. On the top of the container 11 is a fuel inlet pipe 14
However, the pipe ends are arranged so as to be arranged between chrysanthemum-shaped folds of the excess body 12, and an outlet pipe 15 for the passed fuel is arranged substantially in the center.

The excess fuel flows down through the inlet pipe 14 and is introduced into the container through the pipe end opened between the folds of the excess body 12 to remove excess fuel.
After passing through 12, it is guided to the outlet pipe 15 and flows out of the container 11.

[Problems to be Solved by the Invention] By the way, in these conventional excess devices, in order to accommodate a large amount of excess material in a container in order to improve clogging performance, the pipe end of the inlet pipe is placed between the excess pleats. The pleats of the overbody are swayed by the sway of the vehicle and the pulsation of the fuel introduced, and as a result, the pipe end of the inlet pipe and the overbody come into contact, and the outer peripheral edge portion of the pipe end There was a concern that my body would be damaged.

[Means for Solving the Problems] In the present invention, one end of a fold-folded chrysanthemum-shaped body is liquid-sealed with an end plate, and the other end is arranged and fixed substantially concentrically with the center of the container on the upper surface of the container. Then, an outlet pipe and an inlet pipe are arranged on the upper surface of the container, and the inlet pipe is arranged between the folds of the excess body, and the pipe end is outside the pleated outer end of the excess body and on the side surface of the container. It was opened toward.

[Operation] Even if the folds of the excess body in the container sway due to the shaking of the vehicle, the pipe end of the inlet pipe is located outside the outer end of the fold of the excess body,
This pipe end does not come into contact with the excess body, and since fuel is introduced from the pipe end toward the side of the container, the excess body is not directly affected by pulsation, and the fold oscillation is greatly reduced. To do.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, 1 is a container formed of a thin steel plate, and has a bottom surface 2a.
A lower case 2 having a cylindrical side surface 2b and an open upper end and having a peripheral edge portion 2c at the opening edge, and an upper case 3 having a substantially deep dish shape and having a peripheral edge portion 3a at both peripheral edge portions 2c, It is liquid tightly wound together with 3a. In the container 1, an overbody 4 having a chrysanthemum-shaped cross section is formed by aligning the central axis of the container with the central axis of the container and folding it to join the both ends in a liquid-tight manner.
One end is liquid-sealed by an end plate 5 made of a thin plate-shaped thin steel plate, and the other end is disposed and fixed to the inner surface of the upper case 3. On the upper surface 1a of the container 1, a metal inlet pipe 6 having a substantially C shape is formed.
It penetrates 1a and is placed between the folds of body 4,
One tube end 6a is arranged outside the pleated outer end 4a of the excess body 4, and is opened and fixed to the side surface 2b of the container 1 and fixed.
Further, in the center of the upper surface 1a, a J-shaped metal outlet pipe 7 penetrates through the upper surface 1a, and one end thereof has a chrysanthemum shaped body 4.
Is arranged so as to hang inward.

In this reactor, the fuel flowing down in the inlet pipe 6 is
It is introduced into the container from the pipe end 6a of the inlet pipe 6 arranged at the outer end 4a of the excess body 4 toward the side face of the container 1, and this side face
The container 1 and the excess body 4 so as to wrap the excess body 4 along the 2b.
Flows evenly through the gap between, passes through the excess body 4, is guided to the outlet pipe 7, and flows out of the container 1.

[Effects of the Invention] As described above, according to the present invention, the inlet pipe is arranged between the folds of the excess body, and the pipe end is opened outside the fold outer end and toward the side surface of the container. Since the pipe end does not touch the excess body, the pipe end does not touch even when the folds swing, and the fuel can be introduced into the container by reducing the fold swings as much as possible, resulting in damage to the excess body. It is possible to provide not overkill.
