How it works:
The CL2000 rotor is a single moving part, a tapered cylinder that rotates on a fixed axis. Inside the cylinder are two airways side by side. The air channels are formed by one straight tube gently curved at each end adjacent to a 2nd straight tube that features a Y branch to divert the air column. When closed, the straight section of the Y tube lets air flow directly from the handslide to the bell while the other tube is shut off from the F section. When engaged, the Y tube funnels air from the handslide into the F section of tubing. The air then flows through the 2nd passageway and into the bell section.
