Description

[Detailed description of the invention] This invention is based on light oil used as fuel for internal combustion engines.
This relates to a water reservoir part of a centrifugal water separator for fuel used for the purpose of separating and removing water mixed in fuel such as kerosene and A heavy oil.

A conventional centrifugal water separator used in an internal combustion engine has a water separator 2 built into the upper part of a separator body 1, and a water reservoir 3 for storing separated water in the lower part, as shown in the structural diagram of Fig. 1. The water separated by the separator 2 settles due to the difference in specific gravity with the fuel, and is deposited in the water reservoir 3.
It will gradually accumulate.

The amount of separated water can be confirmed from the outside using a float 4 in the water reservoir chamber 3, and when a certain water level is reached, the drain plug 5 at the bottom of the water reservoir chamber is loosened and the water is discharged to the outside.

In such a water separator, when the vehicle body is steeply tilted or vibrates, the water surface in the water puddle 3 naturally tilts, and the water surface momentarily rises, so that part of the water reaches the fuel outlet 6 or is absorbed by the fuel passing through it. There was an inconvenience that water could get mixed in again.

The present invention was developed in view of the above circumstances, and its purpose is to prevent the separated water in the puddle from being mixed into the fuel again when the vehicle is tilted sharply. An object of the present invention is to provide a centrifugal water separator.

Hereinafter, the present invention will be explained with reference to FIG.

In the drawing, 10 is a head, and a case 11 is attached to the lower part of the head 10, and these constitute a separator body 12. A water separator 13 is mounted on the upper side of the case 11, and this water separator 13 is equipped with inner and outer cylindrical bodies 14 and 15, and the inner cylindrical body 14 has a large number of through holes 16 on its circumferential surface. There is also a reservoir 17 formed by the inner and outer cylinders 14 and 15.
A hole 18 is provided in the lower surface of the holder.

A fuel inlet 19 is provided around the circumference of the head 10, and a fuel outlet 20 is provided on the top surface of the head 10. The lower part of the case 11 is formed into a water reservoir part 21, and a drain plug 22 is provided at the lower part of this water reservoir part 21.

A partition wall 23 is provided in the middle portion of the case 11, and the partition wall 23 includes a dish-shaped inclined surface portion 24 and a conduit portion 25 inserted into the water reservoir portion 21 at the center of the inclined surface portion 24.

In the drawing, 26 is a water detection float that floats on the separated water 27.

Thus, the fuel entering from the fuel inlet 19 has its water separated by the water separator 13 and then flows out from the fuel outlet 20. This separated water settles to the inner circumference of the case 11 due to centrifugal force, is received by the inclined surface part 24 of the partition wall 23, is guided from the outer circumference to the center part, flows down the conduit part 25, and flows into the water pool part 21.
It is stored in

If the vehicle slopes sharply, the separated water will flow to the bulkhead 23.
It will not be blocked and danced up, and will not be mixed into the fuel again.

As described in detail above, in the present invention, between the water separator 13 and the water reservoir 21 in the separator main body 12,
Since the partition wall 23 is provided to guide the flow of separated water to the water reservoir section 21, when the vehicle slopes suddenly, the partition wall 2
3, the separated water in the water reservoir 21 does not flow up to the fuel outlet part of the upper part of the separator body 12 or the water separator 13, and can be prevented from mixing with the fuel and flowing out again.
