A gearbox includes a housing including a lubricant reservoir, at least one gear system arranged in the housing, at least one lubricant delivery passage operable to direct a flow of lubricant from a lubricant reservoir onto the at least one gear system, at least one lubricant return passage operable to guide the flow of lubricant to the lubricant reservoir, and a lubricant-out sensor fluidically connected to the at least one lubricant return passage. The lubricant-out sensor is operable to detect a non-pressure based parameter of the lubricant.

A lubricant filler for a lubricant tank of an aircraft engine comprises a filler tube having an upper portion to be disposed outside the volume of the tank and a lower portion to be disposed inside the volume. First and second openings are respectively provided in the upper and lower portions. An oil volume sensor is received in the filler tube through the first opening. A valve is connected to the filler tube and movable between an open position in which the valve provides a fluid connection into the lower portion via the second opening, and a closed position in which the valve blocks the fluid connection into the lower portion via the second opening. A third opening, smaller than both the first and second openings, defined one of: a) through a sidewall of the lower portion of the filler tube to provide a fluid connection between the volume and the lower portion when the lubricant filler assembly is attached to the lubricant tank, and b) through the valve to provide the fluid connection when the lubricant filler assembly is attached to the lubricant tank.

An automatic lubricator for lubricating an object is described, which comprises a housing with a coupling section configured to couple with a lubricant container containing a lubricant, wherein the lubricant container comprises a rotatable shaft with a piston to dispense the lubricant from an output of the lubricant container. The lubricator further comprises an electric motor configured to drive the rotatable shaft of the lubricant container during at least one lubrication action, such that at least a part of the lubricant is dispensable from the lubricant container during the at least one lubrication action, and a power supply configured to supply the electric motor with a supply current during the at least one lubrication action. The lubricator further comprises a control circuitry configured to acquire a current signal indicative of the supply current over time during at least a part of the at least one lubrication action, determine a periodicity of the acquired current signal, and determine, based on the determined periodicity, at least one lubrication parameter indicative of the at least one lubrication action.

Disclosed is a device for lubrication of a unit turning under vacuum, such as a flywheel, where the unit includes an axle rotating relative to a fixed bearing structure, via at least one bearing or roller, and where the unit is placed in an enclosure connected to a vacuum, with: a lubricant reservoir connected by pipes both to the bottom of the enclosure and also to the bearing; and fluid suitable circulator for connecting the reservoir either to the vacuum, for filling the reservoir from the enclosure by gravity, or to the atmosphere for lubricating the bearing. The fluid circulator includes a three-way valve connecting the reservoir either to the vacuum or to the atmosphere.
