Abstract
PURPOSE: To permit delayed operation of valve and obtain smooth switching of flow paths with a simple construction in which a pressure bearing piston is operated in a single action with the opening of a bypass path caused when the pilot signal pressure gradually accumulated in a tank reaches a predetermined pressure.
CONSTITUTION: When compressed air is supplied from the first port 3, a piston 6 is raised by the aid of a spring 12, thus closing the first port 3 and causing an output port 2 to communicate with the second port 4. When a pneumatic signal pressure is then supplied from a pilot port 15, the pressure is gradually introduced through a throttle section 16 into a chamber 17. When a constant pressure is reached, the piston receiving the pressure through a hole 21 begins to descend to open a bypass 18, thus quickly building up the pressure in the chamber 17. As a result, the piston 6 is smoothly lowered to cause the first port 3 to communicate with the output port 2 and close the second port 4. When the signal pressure is removed, a check valve 20 is opened to quickly exhaust air through the path 19 and a bypass 18 so as to return the piston 6.
