Three-port solenoid valve using a valve body for a five-port solenoid valve

摘要

Inexpensive three-port solenoid valves that can be connected to five-port solenoid transfer valves and allow the axial movement of valve discs to be stably guided, are provided. Two valve discs constituting a three-port valve are inserted into a five-port valve body having a supply channel opened at the center of a valve hole; output channels are open on the respective sides of the supply channel; and ejection channels are open on the respective sides of the output channels. A pilot-valve section is used to drive the valve discs. The valve discs use the fluid pressure in the supply channel as returning force for the valve bodies, and each have seal members for switching the output channels between the supply channel and the ejection channels respectively, for communication; and guide sections and for guiding the axial movement of the valve discs, wherein a fluid groove for a fluid flowing through the channel is provided between the plurality of axial guide sections.
