摘要： To provide a speed controller capable of controlling an action speed of an external cylinder in one stroke in a step-wise manner.
The speed controller (1) includes a first flow path (16) and a second flow path (18) that allow a first port (12) and a second port (14) to be in communication with each other. The first flow path (16) is provided with a first check valve (28) for allowing flow from the first port (12) to the second port (14). The second flow path (18) is provided with a first needle valve (32), and an opening hole (28d) of the first check valve (28) is constituted as a part of a flow path. The first needle valve (32) adjusts the flow rate by changing an opening area of the opening hole (28d) with a tip portion (34a) fixed on a piston (30) in the cylinder chamber (20). The speed controller (1) further includes a third flow path (22) allowing the first port (12) and the cylinder chamber (20) to be in communication with each other. The third flow path (22) is provided with a second check valve (46) for allowing flow from the first port (12) to the cylinder chamber (20).
