Regulation of the oil flow in a cooling circuit of a turbomachine

An oil cooling circuit 14 of a turbomachine comprises a flow regulator 15 to regulate oil flow to cooling jets G1-G5 as a function of the oil temperature at the output of a bearing enclosure and a pressure difference at the level of the jet G1-G5. Control based on temperature allows the minimum flow...

Zusammenfassung:	An oil cooling circuit 14 of a turbomachine comprises a flow regulator 15 to regulate oil flow to cooling jets G1-G5 as a function of the oil temperature at the output of a bearing enclosure and a pressure difference at the level of the jet G1-G5. Control based on temperature allows the minimum flow of oil required for cooling to be used, subject to a minimum pressure required at the or each cooling jet. Instead of a regulator, the oil pump may have variable geometry to supply oil at the required rate.
