  • Evacuation and fill valve assembly and method for using the same
    Patent number: 6405534
    Abstract: A non-powered evacuation and fill valve assembly is provided that is suitable for use in connection with hydraulic brake system. The assembly utilizes a pressure differential and/or the properties of material expansion to provide a tight seal. During evacuation of air from the system, the assembly is in an “open” position to permit air to pass. After the air has been evacuated from the system and the system has been filled with fluid, the valve assembly will assume a “closed” position. Thereafter, a tight seal is provided as long as the system is filled with a requisite amount of fluid.
