PURPOSE: A Twist-N-Lock WAP ring assembly is provided to simplify the existing WAP ring assembly by improving the method of suspending the WAP ring assembly from the cam plungers of the Dual Frequency Coupled upper chamber assembly. CONSTITUTION: Three Twist-N-Lock bores(205) are machined every 120 degrees. The Twist-N-Lock bore(205) is essentially composed of two circular bores(610,615) machined next to one another(the reception bore(610) and the lock bore(615)) and set 5 degrees apart(620) on the same radial line(625). The stepped hanger bore(630) allows independent attachment of the stepped hanger.
