Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a radiator reserve tank that communicates with the radiator and is used to adjust the pressure of the radiator as the volume increases and decreases due to thermal expansion and contraction of cooling water.

(Prior Art) Conventionally, as the above-described reserve tank for a radiator, for example, there is a reserve tank described in Japanese Utility Model Application Publication No. 102425/1983.

As shown in FIG. 5, this reserve tank is provided with a reserve tank 52 connected to the hot tank of the radiator via a pipe line 51, and a water volume confirmation part 53 is provided protruding from the side of this reserve tank 52.
The upper surface of this water amount confirmation part 53 is an inclined surface 5.
4, and the above-mentioned water amount confirmation section 53 is communicated with the inside of the reserve tank 52.

Generally, the above-mentioned reserve tank 52 is installed in the lower part of the engine room.
Since equipment such as a bracket for mounting the tank 52, an air cleaner, and a radiator atsupashi loud are arranged around the tank 2, the above-mentioned water level checking section 53 is viewed from the lateral direction indicated by the arrow a in FIG. It is impossible to see it visually, and it must be seen from above, as indicated by arrow b in the figure.

However, in the conventionally structured reserve tank 52,
When checking the water level from above, the original water level 55 and
Since the water below the water level 55 in the water amount checking section 53 appears to overlap, the boundary 55' becomes unclear and there is a problem in that the water amount can be erroneously confirmed.

(Purpose of the invention) This invention has the upper and lower surfaces parallel to each other,
In addition, by providing a water volume confirmation section for checking the water volume upward with a predetermined interval between the upper and lower surfaces, it is possible to accurately predict and confirm the water surface line on the upper surface by tracing the water surface line on the bottom surface of this water amount confirmation section toward the top surface. To provide a reserve tank for a radiator, which enables reliable confirmation of the amount of water in the tank even when the reserve tank is placed in the lower part of an engine room.

(Structure of the invention) This invention is a radiator reserve tank that is connected to the radiator's hot tank through a pipe, and the reserve tank is installed at the lower part of the engine room, and the water volume is measured from above on the side wall of the reserve tank. A water volume confirmation part is provided protrudingly for checking the water content, and the water volume confirmation part communicates with the inside of the reserve tank.
A reserve tank for a radiator, wherein the upper surface and the lower surface are parallel to each other and are formed into an inclined protruding part that slopes with a predetermined interval between the upper and lower surfaces, and the upper surface of the water volume confirmation part is set as a visible part from above. It is characterized by

(Effect of the invention) According to this invention, the above-mentioned water amount confirmation part is formed as an inclined protrusion whose upper and lower surfaces are parallel to each other and which are inclined with a predetermined interval between the upper and lower surfaces, and the above-mentioned water amount is confirmed. Since the top surface of the confirmation part is set as the visibility part from above, visually check this water level confirmation part from above, first check the water surface line on the bottom surface accurately using the air layer below the water level confirmation part, and then By tracing the accurate water surface line on the lower surface toward the upper surface, it is possible to accurately predict and confirm the water surface line on the upper surface.

In other words, since the upper and lower surfaces are parallel to each other and inclined, the water surface line on the upper surface can be accurately predicted from the relative relationship with the water surface line on the lower surface, allowing reliable confirmation of water volume. effective.

(Example) An example of this invention will be described in detail below based on the drawings.

The drawing shows a reserve tank for a radiator, and in FIG.
is installed at the bottom of one corner of engine room 5.

As shown in FIGS. 2 and 3, the above-mentioned reserve tank 4 has a cap 7 fitted onto the upper surface 6a of a milky-white tank body 6 made of polypropylene (so-called PP) and having a predetermined transparency.
A pipe line 9 is attached to the tip of an L-shaped pipe 8 formed integrally with this cap 7, and this pipe line 9 is connected to an upper tank (not shown) of the radiator.

Further, a substantially L-shaped overflow pipe 10 is integrally formed on the upper surface 6a of the tank body 6, and a cap part 11 at the upper end of the overflow pipe 10 and an annular hose holder provided on the outer wall of the rising part of the overflow pipe 10. A drain hose 13 is installed between the drain hose 12 and the drain hose 12.

Moreover, the rear side wall 6 of the tank body 6 described above
b is provided with a protruding water amount checking section 14 for checking the water amount from above.

This water amount checking section 14 communicates with the inside of the tank body 6, and has both an upper surface 14a and a lower surface 14b parallel to each other, and a predetermined interval between these upper and lower surfaces 14a and 14b, as shown in FIG. The upper surface 14a is
is set in the confirmation section from above.

The drawing embodiment is configured as described above,
The action will be explained below.

Now, when checking the water level in the reserve tank 4, for example, visually check the water level confirmation part 14 from above along the line A shown by the imaginary line in FIG.
Accurately confirm the line of the water surface 16 on the lower surface 14b using the air layer below the water amount confirmation part 14, and then check the exact line of the water surface 16 on the lower surface 14b on the upper surface 1.
By tracing in the direction 4a, it is possible to accurately predict and confirm the water surface line on the upper surface 14a, that is, the visible portion.

Namely. Since the upper surface 14a and the lower surface 14b are parallel to each other and inclined, the water surface line on the upper surface 14a can be accurately predicted from the relative relationship with the water surface 16 line on the lower surface 14b, and the water amount can be confirmed reliably. There is an effect that can be done.
