Abstract: A pressure switch including a pressure chamber and a moving disc. The moving disc is moveable in response to a pressure in the pressure chamber to cause contact between a moveable contact and a fixed contact. An orifice communicates a fluid pressure into the pressure chamber. The orifice provides a tortuous path for a fluid flow to reach the pressure chamber. An oil supply system and a generator are also disclosed.

Abstract: A governor of an integrated drive generator includes a housing, and a rotating sleeve extending at least partially through a housing opening in the housing. The rotating sleeve is configured to rotate about a sleeve axis. A gear is secured to the rotating sleeve and rotatable therewith. The gear is located at a sleeve tip of the rotating sleeve outside of the housing. One or more lubricant drain openings are located at a tip surface of the rotating sleeve. The one or more lubricant drain openings are configured to drain a flow of lubricant from the governor.

Abstract: A fluid line termination fitting for a tail cone generator can include a distal body portion configured to insert into a fluid circuit opening of a tail cone generator housing and a proximal body portion configured to receive a male fluid connector. The fitting can include a radial extension disposed axially between the distal portion and the proximal portion. The radial extension can extend radially outwardly relative to the distal portion and proximal portion to limit insertion of the distal body portion into the opening of the tail cone generator housing. The fitting can include a channel structure defining a flow channel through the distal body portion and the proximal body portion. The channel structure can include a proximal channel portion in fluid communication with a proximal opening and a distal channel portion in fluid communication with a distal opening. The fitting can include a threaded section in the proximal channel portion and configured to thread to the male fluid connector and an angled sealing face distal of the threaded section and extending radially inward between the proximal channel portion and the distal channel portion. The angled sealing face can be configured to flushly mate with a complimentary angled surface on the male fluid connector.

Abstract: A shaft system includes an outer shaft including an inner surface defining a conduit and an inner shaft extending within the conduit. The inner shaft includes a radially extending passage having a first end and a second end. A centrifugal force activated damper extends between the outer shaft and the inner shaft. The centrifugal force activated damper includes a first member arranged between the inner shaft and the inner surface at the first end of the radially extending passage, a second member arranged between the inner shaft and the inner surface at the second end of the radially extending passage, and a connecting member extending through the radially extending passage. Rotation of the shaft system causes the first member and the connecting member to shift away from the second member into the inner surface of the outer shaft.

Abstract: A method includes pumping coolant into a cooling system of a generator while the generator is generating electrical power. The method includes regulating flow into the cooling system using a pressure relief valve to recirculate a portion of the coolant back to an inlet of the pump. Using the pressure relief valve includes actuating the pressure relief valve based on input from the cooling system and/or from the generator.

Abstract: An aircraft oil management system includes a generator, pump, and pump control system. The generator is mechanically coupled to a prime mover via a the rotor shaft and is configured to output three-phase power. The pump is mechanically decoupled from the rotor shaft and delivers oil to the generator. The pump control system drives the pump independent of a rotational speed of the rotor shaft.

Abstract: A variable wobbler plate has a stub shaft and a pivot shaft. The pivot shaft has a smaller diameter portion and a larger diameter portion. The smaller diameter portion has a generally cylindrical outer periphery with a flat over a limited circumferential extent and a diameter to opposed portions of the generally cylindrical portion defining a first distance. A second distance is defined from an end of the smaller diameter portion spaced furthest from the stub shaft to an end of the larger diameter portion spaced closest to the stub shaft and measured along a central axis of the pivot shaft and defines a second distance. A ratio of the first distance to the second distance is between 0.60 and 0.75. An integrated drive generator and a method are also disclosed.
