摘要： The invention relates to a butterfly valve (24) for bleeding a compressor for an aircraft turbine engine, the valve including a valve body (32), a butterfly (36), and a device (42) for controlling the angular position of the butterfly, the device (42) including a mobile actuation member (64) connected to the butterfly by a link (70), the member (64) being subjected: to a first adjustable pressure force (F1) applied by air from the compressor, the first force (F1) returning the butterfly (36) to a closed position; and to a second mechanical force (F2) returning the butterfly (36) to an open position, and coming from an aerodynamic torque (C) applied by the air to the butterfly (36), of which the axis of rotation (38) is off-centre relative to the butterfly.

摘要： A turbine engine includes two rotary shafts and a lubrication unit. The lubrication unit has at least one pump which a casing inside of which a rotor is mounted and driven by one of the rotary shafts. The pump casing is rotated by the other rotary shaft such that the actuation of the pump depends on the difference between rotational speeds of the shafts. The shafts are a drive shaft and a fan shaft, respectively, wherein the fan shaft is driven by the drive shaft by means of a reduction gear which is lubricated by the lubrication unit. The reduction gear is annular and the pump passes axially therethrough.

摘要： The invention relates to a lubrication system for turbomachine. The hydromechanical cutoff device is configured to close when a rotation speed of a turbomachine shaft reduces and becomes lower than a first threshold, and wherein the hydromechanical cutoff device is configured to open when the rotation speed of the shaft increases and becomes higher than a second threshold higher than the first threshold.

摘要： In order to fill a reservoir while avoiding laborious manual filling operations, there is added to the existing device, including a supply duct, a pump and a measuring probe, a stop valve designed to interrupt the filling as soon as the desired level has been reached, which is detected for example by an air intake which controls the closure of the valve. Two level indicators are added and make it possible to ascertain either that optimum filling has been achieved or that a malfunction is present in the system. Application to the systems for oil filling of aircraft engine reservoirs from another reservoir arranged within the aircraft, generally common to all the engines.

摘要： A system for supplying a turbine engine with fluid includes a first low-pressure pump, a downstream hydraulic resistance and a high-pressure volumetric pump located between the first low-pressure pump and the downstream hydraulic resistance. The downstream hydraulic resistance includes at least one element selected among a fluid proportioning unit, a filter, a flow meter, an exchanger, a cut-off valve and an injection system. The supply system includes a second low-pressure pump and a supply variator configured such as to vary the flow of fluid supplied to the second low-pressure pump, the second low-pressure pump and the supply variator being located parallel to the first low-pressure pump.
