Multiple charger for refrigerant gas

Abstract

The multiple charger consists of an instrument that allows several operations, and allows several norms in only one tool. This charger can be used in any refrigeration or air conditioning system, except the NH3 systems. It could be manufactured with a favorable metal bar like aluminum, bronze etc. it could be conform from left to right or right to left. The hoses should be manufactured according to the norms of pressure, the type of refrigerant and the necessary connectors. In general the manufacturing of this tool must comply with the U.S standards for security, pressure, temperature, and mechanical resistance.

1 - It is a claim that (A) in FIG. 1 is a metal bar in a T shape to be able to add the needed accessories like fittings, high pressure gauges and valves.  
     
     
         2 - It is a claim that (B) in FIG. 1 is a service valve on the high-pressure side.  
     
     
         3 - It is a claim that (C) in FIG. 1 is a high pressure gauge to charge and vacuum.  
     
     
         4 - It is a claim that (D) in FIG. 1 is a low pressure gauge.  
     
     
         5 - It is a claim that (E) in FIG. 1 is a Pintsch off valve for cans of ⅜ of an inch.  
     
     
         6 - It is a claim that (F) in FIG. 1 is a ¼ inch fitting connector for cylinders.  
     
     
         7 - It is a claim that (G) in FIG. 1 is a low-pressure valve to charge and vacuum.  
     
     
         8 - It is a claim that (H) in FIG. 1 is a fitting connector for systems of ½ of an inch cylinders like R-134-A.  
     
     
         9 - It is a claim that (I) in FIG. 1 is a Pintsch off valve for cans ⅜″, ½″ R-134-A.  
     
     
         10 - There are claims in FIG. 1 (J and K) when we said that (J) is an exit fitting connector in the low-pressure side and (K) is an entrance connector in the high-pressure side of the pressure gauge.  
     
     
         11 - It is a claim in FIG. 4 that (A) is a Pinstch off valve to open the cans and allow the refrigerant charge.  
     
     
         12 - There are claims of this application that (H 1 ), (H 2 ), (H 3 ), (H 4 ), (H 5 ) and (H 6 ) are the connector hoses of this pressure gauge in FIG. 5.
