Patent number: 11703184Abstract: A gas and liquid separation system could be said to have a passage with an inlet connected to receive a mixed gas and liquid flow. An air separation tube extends into the passage at a location downstream of where the inlet is connected with an upstream tube end upstream in the passage relative to a downstream tube end. The upstream tube end provides an obstruction to the mixed gas and liquid flow, to cause separation of the gas from the mixed gas and liquid flow. A liquid tube is connected to the passage at a location downstream of the air separation tube.Type: GrantFiled: April 23, 2021Date of Patent: July 18, 2023Assignee: Hamilton Sundstrand CorporationInventors: Matthew Allen Slayter, Jeff A.
