Abstract

(57) [Summary] [Purpose] The objective is to facilitate water supply work without the need to look at the level display to naturally supply water at a high level, which is an appropriate amount of water, and prevent excessive water supply. [Structure] In a tank attached to a radiator provided with a water supply cap and an overflow outlet on the tank body,
The water supply cap was installed at the same height as the high level of the proper amount of water, a space chamber was provided above the position of the water supply cap, and an overflow outlet was provided above the space chamber.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tank attached to a radiator provided with a water supply cap and an overflow pipe in a tank body.

[0002]

[Prior Art]

 As shown in Fig. 3, many conventional reserve tanks attached to this type of radiator are made of plastic, such as semi-transparent material, so that the height of the water inside can be seen. An overflow outlet 2 is provided for the excess returned cooling water to overflow when the engine temperature rises, and a high level indicator 3 and a low level indicator 4 are provided on the side of the tank. Has been.

A water supply cap 7 is attached to the water supply port 1. A specific example in which the water inlet level is above the high and low positions is disclosed in Japanese Utility Model Laid-Open No. 1-111132.

[0004]

[Problems to be solved by the device]

 In this way, when water is supplied to the radiator attached to the radiator that displays the high and low levels, water must be supplied while observing this indicator in order to prevent excess or deficiency of the water supply. As a result, the water supply work was troublesome.

The present invention solves the above-mentioned problems in the tank attached to the conventional radiator, and even without looking at the level display, water is naturally supplied to a high level which is an appropriate amount of water, and there is no excessive water supply. It is an object of the present invention to provide a tank attached to a radiator that facilitates water supply work.

[0006]

[Means for Solving the Problems]

 The present invention relates to a tank attached to a radiator provided with a water supply cap and an overflow outlet in the tank body, and the water supply cap is installed at the same height as the high level of the proper amount of water, and the water supply cap is located from the position. Is also characterized in that a space chamber is provided above and an overflow outlet is provided above the space chamber.

[0007]

[Action]

 The tank attached to the radiator of the present invention, when the water supply cap is removed and water is supplied at a high level of appropriate water volume, further water supply will overflow from the water supply port, and it will not be possible to supply more water than the appropriate water quantity. It is a thing.

[0008]

【Example】

 Next, an example of implementation of the present invention will be described with reference to FIG. Also in this embodiment, a semi-transparent material is formed so that the internal water level can be seen, and the high level display 3 and the low level display 4 indicating the appropriate water amount are still provided.

Then, a part of the upper surface of the tank main body 5 is lowered to the position of the high-level display 3, and a water supply port 1 is provided on the lowered upper surface 5a, and a water supply cap 7 is attached to this. The space chamber 6 is provided in the tank body 5 between the lowered upper surface 5a and the unlowered upper surface 5b.

The volume of the space chamber 6 is such that, when the cooling water at the height of the high level display 3 is warmed by the heat of the engine and its temperature rises, the volume can be expanded by the temperature rise. Is desirable.

An overflow outlet 2 is provided on the upper surface 5b of the tank main body 5 which is not lowered, and an escape hole for air when accommodating the cooling water expanded by the temperature rise, and a temperature decrease of the cooling water. In addition to replenishing the air to the space chamber 6 at that time, it is also possible to discharge the cooling water that could not be stored in the space chamber 6 due to a temperature rise. The tank body 5 is connected to the radiator by a connecting tube 8 provided at the bottom of the tank body 5.

Therefore, in this embodiment, it is possible to confirm by the high level display 3 and the low level display 4 that the proper amount of water can be maintained, and in the unlikely event that the cooling increased due to the temperature rise of the engine. The water fills the space chamber 6 and overflows from the overflow outlet 2 when the space is exceeded.

However, in the water supply, when the surface of the supplied cooling water reaches the water supply port 1, further water supply overflows from the water supply port 1 and the further water supply is performed in the tank body 5. Can't be done automatically.

Therefore, at the time of water supply, water is automatically supplied to a high level without having to supply water one by one while looking at the water supply level displays 3 and 4. FIG. 2 shows another embodiment of the present invention. In this embodiment, as described above, the water supply is performed only up to the position of the water supply port, so the high level display 3 is omitted. is there. In this embodiment, since the high level display can be omitted, the cost is reduced accordingly.

Although each of the preceding embodiments has been described with respect to the tank attached to the radiator, the present invention can also be applied to a sub tank of a vehicle in addition to this.

[0016]

[Effect of the device]

 As explained above, when the present invention reaches the high level of the proper amount of water during water supply, it will automatically overflow from the water supply port any more and water cannot be supplied, so it is necessary to perform water supply while observing the level display. Therefore, the water supply operation will be easier than before.

Further, since the water is always supplied to an appropriate amount, unnecessary overflow is eliminated when the engine is operating, and contamination due to overflow of cooling water in the engine room is reduced.
