  • Liquid drain system
    Patent number: 4447321
    Abstract: This invention provides a drain system for draining, from a settling chamber of a trapping device, foreign liquid which has separated from a supply liquid flowing through the device. The foreign liquid has a specific gravity greater than that of the supply liquid. The drain system includes a float in the lower part of the chamber and having a specific gravity higher than that of the supply liquid and lower than that of the foreign liquid for floating on foreign liquid in the chamber. An indicator is movable with the float, and a sensor mechanically isolated from the indicator is connected to an electrical signal circuit for causing an actuating signal in response to detection by the float of a predetermined quantity of foreign liquid in the settling chamber. A pump is responsive to such an actuating signal for effecting draining of foreign liquids from the chamber.
