Abstract
PURPOSE:To change a switching valve from a parallel circuit to a tandem circuit by interposing a flow path switching valve and a nonreturn poppet valve between the upper and lower spool valves forming the switching valve. CONSTITUTION:The upper spool valve 30A is provided with a switching valve 31, the lower spool valve 30B being provided with a nonreturn poppet valve 46. When the spool 15A of the valve 30A is moved to the left, an output port 8b communicates with a pressure port 9b, and at the same time the switching valve 31 is switched, so that a poppet 13' is placed on a valve seat 11. Accordingly, pressure oil is not supplied, and even if a spool 15B is moved, an actuator is not operated. When the valve 30A is located at a neutral position, a port 42 of the switching valve 31 is closed to detach the poppet 13' from the valve seat 11 and supply pressure oil to the pressure ports 9a, 9b, whereby the valves 30A, 30B are operated individually.
