Must be done at least several times. There is a drawback in that a switching valve such as a pneumatic solenoid valve connected to a tube and arranged at a different location from the speed controller must be switched manually or by using a control device.

る。In the present embodiment as well, the outer surface of the central portion of the control passage portion 6 is fitted in the hollow hole of the tube clamp portion 3, but the tube clamp portion 3 has a certain range in the axial direction of the control passage portion 6. It can slide only inside. In the state where the tube clamp portion 3 is moved to the rear end side of the control passage portion 6 (state of FIG. 1), the outer surface of the control portion 6 connected to the hollow portion 8 by the through hole 32 in the radial direction of the control passage portion 6. The circumferential groove 31 is opened to the outside through the exhaust hole 2 provided in the tube clamp portion 32. Further, the hollow hole of the tube clamp portion 3 is located in a portion of the outer surface of the control passage portion 6 where there is no groove or hole, and the end of the tube 20 is not connected to the hollow portion 8 and is in a closed state. Therefore, the air of the pneumatic cylinder or the like connected to the tip of the control path portion 6 becomes a free flow 33 and is discharged to the outside from the exhaust hole 2 through the annular hole 10 provided with the check valve 5.

量調整ができるという効果がある。According to the speed controller of the present invention, the tube clamp can be slid on the outer surface of the control path to switch the flow path of the air, and the flow can be performed without operating the switching valve such as the solenoid valve. Since the paths can be switched, the flow rate of compressed air can be adjusted by operating only this speed controller.
