Abstract
The invention relates to an intermediate case for a twin spool turbomachine for an aircraft, comprising at least one lubricant passage and piece () associated with at least one of its vanes (), comprising a lubricant passage () extending along a passage axis () and opening up into the lubricant duct (). The passage axis () and the orifice axis () are also at a spacing from each other along a circumferential direction (), and a connection piece () through which a connection conduit () passes is firstly partially housed in the vane root () so as to create a communication between the connection duct () and the lubricant passage orifice (), and secondly is partially housed in an end-piece support device () or in the lubricant passage end-piece (), such that the connection conduit () communicates with the lubricant passage () in the end-piece.
