設けたことを特徴とする電磁制御減速弁。 A spool hole, an input port communicating with the spool hole and separated in the axial direction of the spool hole, and two output and discharge ports each are formed in the valve body, and communication between the ports is switched within the spool hole. A main valve includes a movable spool, a piston that presses the spool, and a spring that returns the spool to a neutral position in cylinders formed at both ends of the spool hole; It has another spool hole that communicates with the discharge port, and forms within the spool hole a sub-valve consisting of a spool that switches communication between the ports and a piston that presses the spool into a cylinder formed at both ends of the spool hole. At the same time,
A pair of electromagnetic valves are disposed in the valve body to selectively open and close passages leading from cylinders at ends in the same direction of the main valve and the sub-valve to the input port, respectively, and the spool hole of the sub-valve and the two An electromagnetically controlled speed reduction valve characterized in that a throttle valve is provided in each passage leading to each output port.
