  • Publication number: 20200249705
    Abstract: A pressure control unit includes a liquid storage chamber, an inflow port that allows the liquid to flow therein, and an outflow port that allows the liquid to flow out thereof, the pressure control unit controlling pressure of the liquid, wherein at least part of an outer wall of the liquid storage chamber is formed of a flexible film, a pressing plate that presses the flexible film, an urging member that urges the pressing plate, and a valve that opens and closes the outflow port. The pressing plate moves in a direction of expanding the liquid storage chamber, whereby the valve in contact with the pressing plate moves and makes a valve opening degree of the outflow port high. A range of motion of the valve when making the valve opening degree of the outflow port high is limited by a member other than the pressing plate.
