ている。そのため注水時間が長くかがるという問題点が
あった。In the past, for example, many devices have been proposed for injecting cooling water into the radiator of a car, but all of them had a structure in which a liquid level detector was installed inside the water nozzle to detect whether the water was full. In some cases, water droplets are falsely detected by the detector due to puffiness, and additional water injection is required in the later inspection process without water injection being completed.A timer is installed in the detector circuit to prevent this false detection. The water injection process is divided into 2 vacuum pumping, water injection, and vacuum water injection, and is performed intermittently. Therefore, there was a problem that the water injection time was long.

効果がちろ０Even with different refrigerants, a pressurized air path is connected to the full water detection tank, and a check valve installed in the vacuum passage allows surplus water from the full water detection tank to be returned to the radiator, but not through a separate pressurized return path. It is also possible to directly return the water to the water supply tank, and water can be supplied from the same water supply nozzle each time the surplus water is poured into the water supply device and the vacuum passage. Although it is intended for water, it can also be used for other liquids such as oil and gasoline.゛As described above, this invention creates a suction vacuum inside the body to be injected, and then injects water while maintaining the vacuum, and quickly and completely fills the complicated water channels in the body to be injected. Water can be supplied.In particular, since the detection of whether or not the object to be injected with water is filled is carried out by using a spoonful of excess cooling water from the object to be injected into the tank installed in the vacuum passage, the suction and water injection are intensely intersecting. Unlike conventional devices that detect water near the water inlet, there is no malfunction.
Rapid water supply can be performed, and then, at a predetermined full-water level in the water-injected body, the on-off valve of the air introduction passage is opened, the water supply passage is opened, and the excess water in the vacuum passage is suctioned and stored in a tank in the vacuum passage. Therefore, it is possible to supply water to the exact full water level, and as shown in the example, a pressurized air path is communicated with the full water detection tank and a check valve provided in the vacuum passage is used to return excess water from the full water detection tank to the body to be injected. It is also possible to directly return water to the water supply tank through a pressurized return passage provided separately, without having to worry about the excess water in the water supply passage and the vacuum passage. The effect of being able to supply two different types of cooling water from the same water supply nozzle without mixing them together is zero.
