摘要：
An apparatus of an aircraft engine having lubricated moving components is provided. The apparatus comprises a housing having a lubricant cavity for receiving lubricant and a service port cavity, the housing defining a selectively openable service port for accessing the service port cavity. A shaft is mounted for rotation about a rotational axis to the housing. A seal is mounted about the shaft forming a partition between the lubricant cavity and the service port cavity. A vent channel extends between the lubricant cavity and the service port cavity.
