Drainage system for gas turbine supporting bearings
First Claim
1. System of drainage for the supporting bearings of gas turbines, of the type incorporating at least one central shaft (20), surrounded by a series of means of support (21), which result, in their turn, with attachment to a containment housing (22) of those means of support (21), a sleeve (23) for the containment of at least one of the aforementioned support bearings of the turbine and a plurality of pipes (24, 25), respectively, for entry and drainage of lubrication and cooling fluids, characterised by the fact of incorporating, in addition, a series of lateral seals (26), provided in correspondence with a space (10) intended to contain the aforementioned supporting bearing, which creates a pressure difference, which permits the aforementioned fluids to pass from the interior of the aforementioned drainage pipes (25) at pressure and/or sustained speed.

Abstract
A drainage system for gas turbine supporting cushions or bearings, in particular for the second supporting bearing, consisting of a central shaft (20), surrounded by a series of supporting studs (21), which result, in their turn, with connection to a container housing (22) for studs (21), a sleeve (23) for containing the second supporting bearing of the turbine and a series of pipes (24, 25), respectively for the entry and drainage of the lubrication and cooling oil; the system consists of, in addition, a series of lateral seals (26), provided in positions facing the second supporting bearing, which create a pressure difference which permits the oil to pass under pressure within the drainpipes (25) at a well sustained speed.
