A method and a device for the supply of at least one substance (12; 27) into the interspace (3; 22)between mutually moving, coaxial structural elements (1, 1' and 2; 20;20' and 21), wherein the substance (12; 27) is introduced under pressure into the interspace (3), and wherein excess volume of substance (12; 27) that is introduced is caused to exit the interspace (3; 22). The interspace (3; 22) is closed off at at least one axial end thereof by means of at least one annular, spring-loaded seal (9; 16; 23; 24; 37; 38) which is secured in a retaining part (7; 31; 32) associated with one of the structural elements (1, 1'; 20, 20')and has a contact face against the other structural element (2; 21), wherein the substance (12; 27), at a corresponding pressure and simultaneously with the supply into the interspace (3; 22), is also separately supplied to a pressure- applying face of the seal (9; 16; 23; 24; 37; 38).
