Abstract:
The present invention relates to a drain plug (100) with a head (200) comprising at least one transversal through-bore (210) and at least one contact surface (220) concentric to the drain plug (100) longitudinal axis, and by a body (300) comprising at least one through-bore (310) adjacent and complementary to the through-bore (210) of the head (200), at least one annular through-channel (320) of perimeter platform (330) and limited by the surface (220). The body (300) also has one or more sets of alternating fluid-conducting channels, formed by the alternation of annular channels (340, 360, 380), of perimeter platforms (330, 350, 370, 390), of longitudinal walls (331, 351, 371), and of longitudinal openings (332, 352, 372, 382). This invention also relates to a corresponding casing for rotating electrical machine.
