Zusammenfassung:	OF THE DISCLOSURE TURBOMACHINE BLADE WITH FLUIDICALLY COOLED SHROUD THE INVENTION RELATES TO A TURBOMACHINE BLADE (10) , IN PARTICULAR A TURBINE BLADE OF A GAS TURBINE. THE 5 TURBOMACHINE BLADE (10) DESIGNED ACCORDING TO THE INVENTION COMPRISES A BLADE ROOT (11) WITH A COOLING- FLUID FEED (12), A BLADE TIP (13) WHICH IS FORMED WITH A SHROUD ELEMENT (14) . AT LEAST ONE THROUGHF LOW PASSAGE (-19A) WHICH EXTENDS IN THE BLADE LONGITUDINAL DIRECTION 10 IS ARRANGED INSIDE THE AIRFOIL (15) . A SHROUD COOLING PASSAGE (22) IS FORMED IN THE SHROUD ELEMENT AT LEAST ALONG A SECTION OF THE LATTER, THIS SHROUD COOLING PASSAGE (22) BEING CONNECTED VIA AN OPENING (23, 24) TO THE THROUGHFLOW PASSAGE (19A), AND A COOLING FLUID 15 FLOWING THROUGH THIS SHROUD COOLING PASSAGE (22) DURING OPERATION OF THE T-URBOMACHINE BLADE. AT LEAST ONE FLOW- GUIDING ELEMENT (30, 31-DL - 31-D1L, 31-SL - 31-SI2, 32) FOR GUIDING AT LEAST SOME OF THE COOLING-FLUID FLOW FLOWING THROUGH THE SHROUD COOLING PASSAGE IS ARRANGED 20 IN THE SHROUD COOLING PASSAGE AND/OR IN AN INFLOW OR OUTFLOW CO OR FROM THE SHROUD COOLING PASSAGE.
