Depression setting device for enclosure of aircraft turboshaft engine, has lubrication oil circuit formed by nozzle supplied with fluid and degasification tube connected to oil recovery circuit to set depression of enclosure

摘要

The device has a degasification tube (10) connecting a jet pump (11) to an enclosure. The jet pump includes a lubrication oil circuit formed by a nozzle supplied with fluid i.e. oil, under pressure. The degasification tube is used for setting depression of the enclosure and connected to an oil recovery circuit. The fluid under pressure is used to feed the circuit. The circuit of the jet pump is connected to a supply pipe (13) of the oil of lubrication forming derivation of a supply line (16).
