Abstract
The present Freon refilling apparatus for vehicles comprises a tube fitting and a refilling duct. The tube fitting is connected to the refilling duct. The lower end of the tube fitting has a connection port to connect with gas cylinders. A pushrod is movably inserted into the tube fitting in its axial direction. Between the tube fitting and the upper end of the pushrod, there is an operating mechanism which can push the pushrod down to the lower end of the tube fitting. When the pushrod moves downwards, its lower end can make the gas cylinder connected to the tube fitting. The present Freon refilling apparatus for vehicles is applicable to different types of gas cylinders storing Freon. This provides a more convenient way to refill Freon for automobile air conditioners, with a lower cost.
