Patent number: 11174988Abstract: According to one aspect, a lubricant level sensing system for an actuator is provided. The lubricant level sensing system includes a pressure port in an outer housing of the actuator, a pressure sensor, and a pathway from the pressure port to the pressure sensor. The pathway establishes fluid communication between the pressure sensor and a free volume of an internal cavity of the outer housing relative to a lubricant level in the internal cavity such that the pressure sensor detects a pressure of the free volume used to derive the lubricant level.Type: GrantFiled: January 20, 2020Date of Patent: November 16, 2021Assignee: SIKORSKY AIRCRAFT CORPORATIONInventors: Claude G.
