ABSTRACT:
A device for separating oil from an oil/gas mixture in a refrigeration or heat pump system includes a cylindrical housing circumscribing a central axis with upper and lower end caps. A scroll-shaped separator baffle disposed in the housing defines a flow path extending radially-inward in a spiral manner from a peripheral region of the housing toward the central axis of the housing. An inlet conduit in the upper end cap directs an oil/gas mixture into the housing. An upper baffle plate supporting an upper end of the separator baffle directs the oil/gas mixture from the inlet to the peripheral region of the housing and into the separator baffle. The oil in the mixture generally separates from the gas in the mixture and deposits on the wall of the separator baffle the mixture flows radially inward through the separator baffle. An outlet conduit in the lower end cap aligned with the central axis and extending upwardly into the separator baffle directs the resulting oil-free gas stream from the housing. The oil on the baffle wall coalesces and drains downwardly through filter media supported in a lower baffle assembly at a lower end of the separator baffle. The filtered oil can be either directed through a drain tube to appropriate components, or directed through an opening in the outlet conduit for re-introduction into the gas stream.
