3-port solenoid valve with 5-port solenoid valve body

摘要

It provides a three-port solenoid valve that can be used in series with a five-port solenoid conversion valve and the like at low cost, and also makes it possible to stably guide the axial movement of the valve body.;5 ports having a supply fluid passage 21 opened at the center of the valve hole 20, output fluid passages 22A, 22B opened at both sides thereof, and discharge fluid passages 23A, 23B opened at both sides thereof. Using the valve body 15 for valves, two valve bodies 25A, 25B constituting a three-port valve are inserted into the valve holes, and they are driven by the pilot valve portion 12. The valve body uses the fluid pressure of the supply fluid passage 21 as a return force, and supplies the output fluid passages 22A and 22B to the supply fluid passage 21 and the discharge fluid passage 23A. ) And (B), sealing members 28A, 28B, 29A, and 29B, which are connected to each other and are connected to each other, are provided, and both valve bodies have guide portions 35 for guiding movement in the axial direction. While providing the 36, the fluid passage groove 37 of the fluid flowing through the fluid passage is interposed between the plurality of axial guide portions 36.
