  • Publication number: 20210285564
    Abstract: A solenoid valve includes a valve housing having a first space that communicates with an inlet flow path and a second space that communicates with an outlet flow path. A solenoid is provided in the valve housing to surround the first space. A flow path guide is provided in the first space and has an inflow path communicating with the first space. A plunger is rectilinearly moved in the flow path guide by the solenoid. A valve member is connected to the plunger and opens or closes the outlet flow path based on a plunger movement. A spring member provides elastic force allowing the valve member to move in a direction in which the valve member blocks the outlet flow path. A fluid guide part is formed in the plunger and guides a fluid, supplied into the inflow path via the first space, selectively to the second space.

  • Publication number: 20210180707
    Abstract: A discharge valve is provided in a recirculation line through which gas discharged from a fuel cell stack recirculates to the stack. The discharge valve opens or closes a discharge line through which a fluid in the recirculation line is discharged. The discharge valve includes a valve body connected to the discharge line and a drive part disposed in the valve body to be movable vertically. A diaphragm is coupled to a lower end of the drive part and selectively opens or closes the discharge line based on the vertical movement. The drive part switches between a closed state in which the discharge line is closed by the diaphragm, a first opened state in which the discharge line is opened to a first opening degree, and a second opened state in which the discharge line is opened to a second opening degree greater than the first opening degree.
