  • Discharge valve unit and fluid device
    Patent number: 11578814
    Abstract: The discharge valve unit includes: a valve case configured to be detachably attached to the housing and including a second reservoir for liquid configured to communicate with the first reservoir when the valve case is attached to the housing; and a second valve mechanism disposed in the second reservoir and including a second discharge hole having a larger opening diameter than that of the first discharge hole and a second valve member accommodated in the second reservoir and configured to open and close the second discharge hole. The second valve mechanism includes a spring configured to bias the second valve member in a valve opening direction. When a pressure of the second reservoir increases to a predetermined value, the second valve member closes the second discharge hole against a biasing force of the spring.
    Type: Grant
