AIR TURBINE STARTER HAVING A LOW DIFFERENTIAL CHECK VALVE

摘要

An air turbine starter (100) is provided that includes a check valve assembly (173). The check valve assembly (173) comprises a valve body (181), a valve seat (179) and a valve element (177). The valve body (181) includes an inlet port, an outlet port, and a flow passage (182) extending therebetween. The valve seat (179) is coupled to the valve body (181), extends at least partially into the flow passage (182) and has an opening therethrough. The valve element (177) is disposed within the flow passage (182) between the valve seat (179) and the valve body outlet port. The valve element (177) is also configured to translate axially between an open position and a closed position in response to a pressure differential between the inlet and outlet ports.
