<p>PURPOSE: A single-acting directional control valve is provided to stably conduct a returning process of a valve rod using a returning spring, and to prevent the generation of a low pressure area around an exhaust port. CONSTITUTION: A single-acting directional control valve includes a valve body(10), a valve chamber(11), a valve rod(30), a switching driver(50), and a returning spring(41). The valve body includes a supply port(19), an outlet port(20), and an exhaust port(21). The valve chamber is connected to the ports, and is installed inside the valve body. The valve rod is stored inside the valve chamber to be slid toward the axial direction. The switching driver and the returning spring drive the valve rod. The valve chamber includes a supplying valve sheet surrounding a flow path which connects the supply port and the outlet port.</p> |
