Problems solved by technology

Therefore, the conventional coolant filling apparatus is more space occupying, and the vacuum generator thereof is more possibly knocked against which may cause the main body disengaged with a coolant system of the motor vehicle when in use.
Besides, the joint portion between the main body and the vacuum generator is worn-down and becomes loose gradually, which may break the vacuum when the coolant filling apparatus is in use.

Embodiment Construction

[0015]Please refer to FIG. 1, 2, 5 and 6. The coolant filling apparatus of the present invention includes a plastic body 10, a pressure gauge 20, a vacuum generator 50, a first passage, a second passage and a third passage.

[0016]The pressure gauge 20 and the vacuum generator 50 are directly installed in an interior of the plastic body 10, and the first and second passages are disposed in the interior of the plastic body 10 as well. A joint opening is formed on the plastic body 10 to receive the pressure gauge 20 therein, and a gauge end of the pressure gauge 20 is disposed in a vacuum section of the second passage, provided when the coolant filling apparatus is in use, to gauge pressure therein.

[0017]The first and second passages communicate with each other. Two terminals of the first passage are formed with a first entrance 41, for connecting to a compressor (not shown), and a first exit 42 respectively. A first valve 45 is disposed on the first passage near the first entrance 41 t...

Abstract

A coolant filling apparatus for a motor vehicle is provided, which includes a plastic body, a pressure gauge, a vacuum generator, a first passage, a second passage and a third passage. The pressure gauge and the vacuum generator are directly installed on the plastic body, and the first and second passages are disposed in an interior of the plastic body. A tube is formed is disposed on the second passage, and one terminal of the tube is formed with a threaded section to be engaged with the second passage, another terminal thereof connects to a metallic tapered body, which is sleeved by a rubber tapered sleeve.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a maintenance apparatus of a motor vehicle, and particularly relates to a coolant filling apparatus for filling a cooling system of the motor vehicle.[0003]2. Description of the Prior Art[0004]As disclosed in Taiwan patent No. M249880 and U.S. Pat. No. 6,360,790, a conventional coolant filling apparatus includes a main body and a vacuum generator, in which the vacuum generator is additionally attached onto the main body. Therefore, the conventional coolant filling apparatus is more space occupying, and the vacuum generator thereof is more possibly knocked against which may cause the main body disengaged with a coolant system of the motor vehicle when in use. Besides, the joint portion between the main body and the vacuum generator is worn-down and becomes loose gradually, which may break the vacuum when the coolant filling apparatus is in use.SUMMARY OF THE INVENTION[0005]The main object...
