    摘要: A rotary valve is interposed between an intake pump and an exhaust pump for supplying an air, and at least one suction head or one nozzle that performs a predetermined operation upon reception of the air supplied from the intake and exhaust pumps, to supply/stop supplying the air. This rotary valve includes a valve body, a main body, a notch, and a hollow portion. The valve body is rotatably driven in a cylinder. The main body rotatably supports the valve body. The notch is formed in a circumferential surface of the valve body and is connected to the intake pump. The hollow portion is formed in the valve body in an axial direction and is connected to the exhaust pump.
