In a described embodiment, an automotive air conditioning refrigerant charging apparatus includes an R-134a system quick connect connector, a pressure gauge and a refrigerant can valve. The pressure gauge and the valve are simultaneously and permanently connected to the quick connect connector.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . An automotive air conditioning refrigerant charging apparatus, comprising: 
 a quick connect connector operative to connect to a low pressure service port of an R-134a air conditioning system;    a pressure gauge; and    a refrigerant can valve,    the pressure gauge and valve being connected simultaneously to the quick connect connector.    
     
     
         2 . The apparatus according to  claim 1 , wherein the pressure gauge and valve are connected to the quick connect connector using at least one hose.  
     
     
         3 . The apparatus according to  claim 1 , wherein a first hose is connected between the pressure gauge and the quick connect connector, and wherein a second hose is connected between the valve and the pressure gauge.  
     
     
         4 . The apparatus according to  claim 3 , wherein the first hose is connected between the quick connect connector and a T-fitting connected to the pressure gauge, and wherein the second hose is connected between the T-fitting and the valve.  
     
     
         5 . The apparatus according to  claim 1 , wherein the pressure gauge is permanently connected to the quick connect connector.  
     
     
         6 . The apparatus according to  claim 1 , wherein the valve is permanently connected to the quick connect connector.  
     
     
         7 . The apparatus according to  claim 1 , wherein the pressure gauge and the valve are each permanently connected to the quick connect connector.  
     
     
         8 . An automotive air conditioning refrigerant charging apparatus, comprising: 
 a quick connect connector operative to connect to a low pressure service port of an R-134a air conditioning system;    a pressure gauge; and    a refrigerant can valve,    at least one of the pressure gauge and valve being permanently connected to the quick connect connector.    
     
     
         9 . The apparatus according to  claim 8 , wherein both of the pressure gauge and valve are permanently connected to the quick connect connector.  
     
     
         10 . The apparatus according to  claim 8 , wherein the pressure gauge and the valve are connected simultaneously to the quick connect connector.  
     
     
         11 . The apparatus according to  claim 8 , wherein the pressure gauge and valve are connected to the quick connect connector using at least one hose.  
     
     
         12 . The apparatus according to  claim 8 , wherein a first hose is connected between the pressure gauge and the quick connect connector, and wherein a second hose is connected between the valve and the pressure gauge.  
     
     
         13 . The apparatus according to  claim 12 , wherein the first hose is connected between the quick connect connector and a T-fitting connected to the pressure gauge, and wherein the second hose is connected between the T-fitting and the valve.  
     
     
         14 . An automotive air conditioning refrigerant charging apparatus, comprising: 
 a quick connect connector operative to connect to a low pressure service port of an R-134a air conditioning system;    a pressure gauge;    a refrigerant can valve; and    a T-fitting connected to each of the quick connect connector, the pressure gauge and the valve.    
     
     
         15 . The apparatus according to  claim 14 , wherein at least one of the pressure gauge and valve is permanently connected to the T-fitting.  
     
     
         16 . The apparatus according to  claim 14 , wherein both of the pressure gauge and valve are permanently connected to the T-fitting.  
     
     
         17 . The apparatus according to  claim 14 , wherein the pressure gauge and the valve are connected simultaneously to the T-fitting.  
     
     
         18 . The apparatus according to  claim 14 , wherein the pressure gauge and valve are connected to the quick connect connector using at least one hose.  
     
     
         19 . The apparatus according to  claim 14 , wherein a first hose is connected between the pressure gauge and the quick connect connector, and wherein a second hose is connected between the valve and the pressure gauge.  
     
     
         20 . The apparatus according to  claim 19 , wherein the first hose is connected between the quick connect connector and the T-fitting, and wherein the second hose is connected between the T-fitting and the valve.
