Abstract
A liquid separator (10) for separating two immiscible liquids having different specific gravities, for example, a first liquid comprising water and a second liquid comprising oil. The liquid separator (10) has a housing (12) that defines a separation chamber (14) and liquid inlet (16), a first liquid outlet (18) and a second liquid outlet (20) mounted above the first liquid outlet (18). A float 26 is positioned within separation chamber 14 to translate in the vertical direction and has a specific gravity between that of the first and second liquids so that it floats at approximately the interface (28) between the two liquid phases (30 and 32). Valve closure devices (38 and 40) contact valve seats in the valves 46 and 56 of first and second liquid outlets (18 and 20) to control the flow of separated liquids from separation chamber 14 as determined by the level of the interface (28) and the length of the valve rods (34 and 36).
