  • Dispenser device for dispensing metered doses of viscous material
    Patent number: 6200055
    Abstract: A dispensing device including a pump assembly for pumping out the viscous liquid material stored in the device. The pump has a cylinder and a piston disposed within the cylinder, wherein the cylinder includes a cylinder inlet valve and the piston includes a cylinder outlet valve. Each operation of the pump assembly causes the piston to move in a first direction toward the cylinder inlet valve and in a second direction away from the cylinder inlet valve. The movement of the piston in the first direction causes the cylinder inlet valve to close and the cylinder outlet valve to open. The movement of the piston in the second direction causes the cylinder inlet valve to open and the cylinder outlet valve to close.
