Abstract
An oil jet for lubricating members such as bearings inside a turbine engine, includes a main pipe for supplying oil, at least one secondary oil discharge pipe through which the oil is sprayed onto the member, and a connection area which is for connecting the secondary pipe to the main pipe and which includes a junction angle between the main pipe and the secondary pipe, wherein the connection area includes an inner wall in contact with the oil, the inner wall being at least partially curved at the junction between the secondary pipe and the main pipe such that the junction angle inside the connection area is at least partially rounded.
Claims9
An oil nozzle for lubricating a member within a turbomachine, comprising:
- a main oil supply duct comprising multiple bores, each one forming a duct connection zone,
- secondary oil outlet ducts through which oil is sprayed onto the member, and
- the duct connection zones for connecting the secondary oil outlet ducts to the main oil supply duct, each duct connection zone including a junction angle between the main oil supply duct and one of the secondary oil outlet ducts,
- wherein each duct connection zone includes an inner wall in contact with oil, said inner wall being at least partially curved at the junction between one of the secondary oil outlet ducts and the main oil supply duct so that the junction angle inside the duct connection zone is at least partially rounded, said inner wall including a bulge extending over at least one portion of a circumference of the junction angle between the one secondary oil outlet duct and the main oil supply duct and covering a salient angle of said junction angle.
