Abstract
A swivel valve has a valve body having an elongated bore with both the valve body and the bore having first and second ends. A gas or fluid port is located in the first end of the valve body and is in communication with the first end of the bore. A passageway extends from the second end of the bore and terminates in an annular groove extending around the outer surface of the valve body. A swivel connection is rotatably mounted on the valve body around said annular groove and has a passageway in communication with the annular groove. Sealing rings are located on opposite sides of the annular groove to prevent the escape of gas from the groove to the atmosphere between the swivel connection and the outer surface of the valve body, and to equalize the gas pressure forces on the swivel connection.
