  • Apparatuses for the separation of a lighter liquid from a mixture of a heavier and a lighter liquid
    Patent number: 3957638
    Abstract: A counterbalance and control system for a gravitational oil and water separator using a floating inverted bell comprises a linkage, sealed coupling shaft and weight system for controlling an outlet valve for the separated oil accumulated beneath the bell during operation of the separator. The linkage and shaft system transmits motion of the bell in response to accumulated oil in a fluid-tight manner to the control system, which is located exteriorly of the separator vessel. Counter-weight masses are connected to the bell through the linkage and shaft system to enable the control system to respond to the accumulation of a predetermined weight of oil beneath the bell.
