Abstract:
A coolant deaeration bottle for operative connection to an engine cooling and cabin heating system of an internal combustion engine for an automotive vehicle having a degassing chamber comprising an enclosing outer wall and a plurality of partitions therein intersecting one another to at least divide said chamber into a plurality of cells defined by a vertically extending coolant inlet cell and an adjacent vertically extending coolant receiving and outlet cell, said cells having discrete upper and lower end portions, an opening in the upper end portion of said inlet cell for receiving liquid coolant from said system, said inlet cell having a second opening in the lower portion thereof for transmitting flow from said coolant inlet cell to said adjacent coolant receiving cell, said outer wall of said degassing chamber having an outlet passage therein operatively connecting said coolant receiving cell for returning coolant to said system, said cells being hydraulically interconnected by said openings so that fluid flows through said degassing chamber in a circuitous path for deaeration of said coolant when said coolant is operative to effect engine cooling operation, said coolant being confined in said inlet cell to provides a liquid trap to block the flow of air degassed from said coolant from said degassing chamber back into said engine on engine cool down so that air will not collect in the cabin heating component of said system.
