Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle vacuator valve which is fitted to a water or dust discharge port provided at a lower portion of an air cleaner for cleaning air supplied to an automobile engine. Belong to.

[0002]

2. Description of the Related Art Conventional air cleaners for automobiles are attached to the rear part of the front tires. Therefore, there is a problem that the mud lifted up by the front tires may enter through the drain when the vehicle is running. I installed a mudguard cover in the front to deal with this problem.

Further, Japanese Utility Model Laid-Open No. 3-17268 discloses that
"In a vacuator valve that is fitted into the dust discharge hole that projects from the lower end of the air cleaner, the upper end is fitted into the vacuator valve and prevents the muddy water that is splashed from below from adhering to the vacuator valve. Air cleaner vacuator valve with a skirt cylinder in a substantially vertical direction. "

[0004]

However, the actual Kaihei 3-1.
What is described in Japanese Patent No. 7268 is to prevent muddy water from adhering by attaching a skirt cylinder in the vertical direction of the vacuator valve part, and to run in rain, especially in heavy rain or in deep water pools. In this case, the vertically mounted skirt cylinder may cause damage to the inside of the air cleaner, and if the engine speed is increased, the load on the air cleaner may cause a vacuator valve. Because the lip of the mouth is not sufficiently sealed, the negative pressure of the air cleaner acts to make it easier to inhale water at a low water level compared to the case where the skirt-shaped tube is not attached through the lip, Through which water, which is an incompressible fluid, enters the combustion chamber of the engine, and in the worst case, this causes so-called window deformation or deformation of the engine. Have a higher risk of causing over ter hammer phenomenon. Further, there is a problem that the splashed muddy water or the like of the front wheels may adhere to the lips and hinder the originally intended function.

The present invention solves the above-mentioned problems of the prior art, and prevents muddy water from the vacuator valve without hindering the discharge of dust, water, etc. in the air cleaner.
An object of the present invention is to provide a vacuator valve for an automobile that can prevent water from entering.

[0006]

A vacuator valve for an automobile according to the present invention is a vacuator valve for an automobile, which is attached to a cylindrical hanging portion of a drainage port at a lower portion of an air cleaner. It is provided on the flat part of the funnel-shaped part as an integral part of it or as a separate part,
The bent portion of the elastic tongue covers the slit-shaped drainage port at the lower end of the valve, and the tip of the elastic tongue is in close contact with the outer surface of the flat portion of the valve.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a vehicle vacuator valve according to the present invention will be described with reference to FIGS. 1 to 5. Figure 1 shows the first vacuator valve for automobiles.
FIG. 2 is a side sectional view of the embodiment of FIG.
It is a figure which shows a part seen from a line in a section, Drawing 3 is a front view of a vacuator valve for vehicles, Drawing 4 is a side sectional view of a 2nd example of a vacuator valve for vehicles. FIG. 5 is a side sectional view of a third embodiment of a vehicle vacuator valve.

The first embodiment of the automotive vacuator valve will be described with reference to FIGS. 1 to 3. The vacuator valve 4 includes a mounting portion 11, a funnel-shaped portion 5, a flat portion 6, and a slit-shaped drainage port 7. And an elastic tongue member 9,
The upper end of the vacuator valve 4 is fitted to the lower end of the cylindrical hanging part 3 by fitting the mounting part 11 to the cylindrical hanging part 3 of the drain port 2 at the lower part of the air cleaner 1, and its outer peripheral surface is It is fixed with a fixing band 12. Flat portions 6, 6 are formed on the funnel-shaped portion 5 of the vacuator valve 4, and the lower ends of the flat portions 6, 6 are slit-shaped drainage ports 7.
Is formed. A bent portion 8 is formed in an extension of one flat portion 6, the bent portion 8 covers the slit-shaped drainage port 7, and a tip portion 10 thereof forms an elastic tongue member 9 that is in close contact with the flat portion 6. There is.

The vacuator valve 4 including the elastic tongue member 9 is formed of an elastic body such as natural rubber or synthetic rubber.

The second embodiment of the vacuator valve for automobiles is, as shown in FIG. 4, a funnel of a vacuator valve 4 provided in a cylindrical hanging part 3 of a drain port 2 at the bottom of an air cleaner 1. One end 13 of an elastic tongue member 9 which is separate from the flat portion 6 below the plate-like portion 5 is adhered and fixed by an adhesive, and the middle portion is formed as a bent portion 8 and the tip portion 10 thereof is The elastic tongue member 9 is extended to be in close contact with the flat portion 6.

A third embodiment of the vacuator valve for an automobile will be described with reference to FIG.
Fasteners 15 and 15 made of synthetic resin-made concavo-convex portions are attached to the outer surface of the flat portion 6 and the surface of the elastic tongue member 9 corresponding thereto in the embodiment, and the outer surface of the flat portion 6 is attached by the fasteners 15 and 15. The elastic tongue member 9 is closely attached, and the bent portion 8 of the elastic tongue member 9 covers the lower surface of the slit-shaped drainage port 7.

Since the elastic tongue member 9 is provided so as to be in close contact with the flat portion 6, the elastic tongue member 9 does not inadvertently disengage from the flat portion 6 due to the wind pressure caused by the running of the automobile, and the drainage port of the vacuator valve for automobiles. Even if mud adheres to the vicinity,
Water stored in the funnel-shaped portion 5 of the vacuator valve 4 from the water draining port 2 of the air cleaner 1 through the cylindrical hanging portion 3 flows down through the drainage gap 7 of the flat portion 6 below the funnel-shaped portion 5. Then, water drops 14 are applied from both sides of the lower end of the elastic tongue member 9.
And is discharged outside the car.

The elastic tongue member 9 may be integrated with the flat portion 6 or may be a separate member, and the integrated member is the one of the first embodiment and the separate member is the one of the second embodiment. Figure 3
belongs to. In any case, the bent portion 8 of the elastic tongue member 9 covers the slit-shaped drainage port 7, and the tip of the elastic tongue-shaped member 9 is brought into close contact with the outer surface of the flat portion 6 to prevent water from the slit-shaped drainage port 7. Dust is discharged from both sides of the bent portion 8. Further, regardless of whether the elastic tongue member 9 is integral with the flat portion 6 or is a separate body, if a fastener is provided between the flat portion 6 and the elastic tongue member 9, mutual adhesion is further improved. .

Since the elastic tongue-shaped member 9 covers the slit-shaped drainage port 7 with the bent portion 8, mud and dust do not enter from the slit-shaped drainage port 7, so a special cover or cover is required. Therefore, the vacuator valve of the air cleaner 1 having a simple structure can be provided at low cost without impairing the drainage function of water.

Even if the water drainage port 2 of the air cleaner 1 is immersed in the water pool, the elastic tongue member 9 and the bent portion 8 thereof cover the slit-shaped drainage port 7, so that muddy water or the like is contained in the vacuator valve 4. It is extremely hard to penetrate compared to other things.
