ABSTRACT:
An assembly of isolation valves (42, 44, 46) coupled to vaporizers (54, 56, 69), and a corresponding number of valve control levers (66, 68, 70) connected by an interlock mechanism that allows only one of the levers to be in an on position at any time. The interlock mechanism includes a cable (80, 81, 82) between each unique pair of control levers, the cables being only long enough to permit one lever of each unique pair to be moved to the on position. Each lever has a camming roller (66d, 68d, 70d) that engages and rotates a forked valve cam (86) to switch the valve on or off.
