Description

[Detailed Description of the Invention] The present invention relates to a water separation device for liquid fuel such as gasoline and light oil.

Conventionally, in this type of moisture separator, liquid fuel containing moisture flows in from the inlet of the upper case, passes through a moisture separation member disposed at the upper part of the case, and then flows from the outlet vibrator vertically installed in the upper case. The structure is such that the water supplied to the outside and separated and removed from the water separation member is immediately accumulated in a water drop settling section at the bottom of the case.

With such a configuration, the moisture in the fuel can be removed to some extent, but since the moisture separation member forms fine water droplets and reaches the water droplet settling part of the case, the liquid fuel that passes through the moisture separation member and flows to the outside from the outlet vibrator. Water droplets may be carried away by the flow of water, and liquid fuel containing moisture is supplied to internal combustion engines, causing various problems such as poor starting, uneven combustion, and rust on fuel injection equipment. .

The present invention has been developed to solve these problems, and uses a simple structure to condense the separated and removed water into large water droplets or string-like water droplets, thereby eliminating the flow of liquid fuel from being carried away. The object of the present invention is to provide a liquid fuel moisture separation device that does not adversely affect an internal combustion engine or the like.

One embodiment of the present invention will be described with reference to the drawings. A is a case constituted by an upper case 1 and a lower case 2 screwed together in a tight manner, and the centrifugal direction of the upper case 1 constituting the case A is An inlet 3 for liquid fuel is formed in the inlet 3 .

Reference numeral 4 denotes a separator whose periphery is held between the threaded portion of the upper case 1 and the lower part 2, and which has a relatively large diameter through hole 5 in the center. An outlet vibrator 6 for filtered liquid fuel, which is integrally vertically installed in the center of the upper case 1, is penetrated therethrough.

Reference numeral 7 denotes a moisture separating member which is arranged concentrically to surround the through hole 5 and the outlet vibrator 6, and whose upper surface is in pressure contact with the lower surface of the separating plate 4 in a watertight manner. A moisture separator 8 having a larger diameter than this is pressed into contact with the water separator 8 in a watertight manner.

A hole 9 is provided in the center of this moisture separator 8, and this hole 9 is fitted into a threaded portion 10 formed at the lower end of the outlet vibe 6, and a nut 11 is screwed into this threaded portion 10.
The moisture separator 8 is fixed to the exit vibe 6 by.

A water reservoir 12 is formed between the peripheral standing wall 8a of the moisture separator 8 and the outer surface of the moisture separating member 7, and further between the upper end surface of the peripheral standing wall 8a of the moisture separator 8 and the separating plate 4.
A channel 13 for liquid fuel from which moisture has been removed between the lower surface of the
was formed.

And on the bottom plate of the water separator 8 facing the water storage section 12,
Small holes 14 are drilled at appropriate intervals for accumulating accumulated moisture as large water droplets or thread-like water columns in the water drop settling section 2a of the lower case 2.

As the above-mentioned moisture separating member 7, glass wool, wire mesh, nonwoven fabric, sponge, etc., to which moisture easily adheres, that is, highly hydrophilic, are used singly or in a composite structure.

In the figure, 15 is a backing, and 16 is a drain plug.

The operation will be explained based on the above embodiment. The liquid fuel containing moisture that enters the upper case 1 from the inlet 3 becomes a vortex and enters the moisture separation chamber from the through hole 5, and enters the moisture separation member 7.
The liquid fuel passes from the inside to the outside, enters the lower case 2 through the flow path 13, and then flows to the outside from the outlet vibe 6.

When the liquid fuel passes through the moisture separation member 7, moisture is separated and removed.

The removed moisture gradually grows, flows out to the outside, and is accumulated in the reservoir 12 of the moisture separator 8.

As the amount of accumulated moisture gradually increases, it
The water drops settle from the small (L14) provided in the lower case 2 as large water droplets or a water column, and are not carried away by the liquid fuel flowing concentratedly into the outlet vibe 6.
and is removed to the outside from the drain plug 16 as appropriate.

As described above, according to the present invention, the water removed by the water separating member is accumulated in the reservoir of the water separator, and from the small holes provided in the reservoir, the water changes into large water droplets or water columns, and the water droplets settle into the water column. It has the advantage of being able to reasonably prevent water droplets from being carried away by the flow of liquid fuel that is supplied to the outside via the outlet vibrator.

Therefore, since the purpose can be achieved with a small water separation member, the entire device can be miniaturized, which not only reduces costs but also has practical benefits such as not having a negative impact on internal combustion engines and fuel injection equipment. The effect is extremely large.
