  • Pressure control device for an inkjet pen
    Patent number: 6644795
    Abstract: A pressure control device for an inkjet pen. The inkjet pen is provided with a reservoir having a first opening and maintaining a back pressure established therein. The pressure control device comprises a bag, a pressure plate, an isolation member, a bias member, and an elastic member. The bag, disposed inside the reservoir, communicates with outside the reservoir so as to expand inside the reservoir. The pressure plate is disposed inside the reservoir and adjacent to the bag so as to move inside the reservoir. The bias member is disposed inside the reservoir and adjacent to the pressure plate, the isolation member, and the reservoir respectively such that the bag expands to move the pressure plate when the back pressure inside the reservoir changes, then the pressure plate moves the bias member so that the isolation member separates from the first opening.
