Abstract

AN INJECTION VALVE THAT INCLUDES A BODY HAVING INLET AND OUTLET ENDS CONNECTED BY A PASSAGE WHICH HAS SUCCESSIVE CYLINDRICAL AND TAPERED LENGTHS. A STEM HAVING A CYLINDRICAL PORTION SOMEWHAT SMALLER THAN THE CYLINDRICAL LENGTH OF THE PASSAGE AND A TAPERED PORTION THAT MATCHES THE TAPERED LENGTH OF THE PASSAGE EXTENDS INTO THE PASSAGE. A BIASING MEANS CONNECTED BETWEEN THE VALVE BODY AND THE STEM URGES THE TAPERED PORTION OF THE STEM INTO ENGAGEMENT WITH THE TAPERED LENGTH OF THE PASSAGE TO SEAL AND CLOSE OFF THE PASSAGE AT THE OUTLET END.
