Abstract A control valve (100,200) with a two-piece shifting mechanism is provided. The special control valve has two levers, one is a sealing lever (106,206) and the other is a shifting lever (104,204). The sealing lever (106,206) has a channel (116,216) on one of its ends to couple together different ports (SP, S, P, IS) to change the airflow direction. Each lever has its own axis. The shifting lever and the sealing lever interact through an oval opening (114) and a cylindrical boss (112), obtaining two angular range motions. When a small angular input is put on the shifting lever it will produce a large angular output at the second end of the sealing lever. It will achieve a multiple-position switching.
