Abstract
PURPOSE: To provide a position set maintaining device to permit for controlling full range of the operation of a device to be driven and for turning on or off.
CONSTITUTION: For example, in operating to open a valve 2, magnet valves 22 and 23 are switched as shown by diagram (white: open, black: close.), turning a handle 32, sliding a clutch 27 against a frame 41 to turn a pinion 26, causting to depress a valve rod 20 of a pilit valve P by means of a rack 19. Ports a, b, f are, then, opened to permit an oil supplied from a oil supply tube 24 to push up a piston 7. In closing a port b by a control rand 20b, oil feed to the cylinder 8 is discontinued, causing the valve 2 to maintain at an intermediate opening. Besides, in opening under the connected condition, oil stream i, c is opened, closing oil stream j, allowing to apply oil pressure to the top of a piston 20d.
