<p>The sealing ring (1), between two machine parts (2,3) moving against each other, has a T-shape fitting into the gap (4) between them and with its stem (6) floating within a groove (5) in one part (2). The axial sealing head (7) moves against the surface (8) of the other part (3). The sealing ring axial surfaces (9,10) bear against the surfaces (11,12) of the groove, leaving a channel (13,14) around the stem for a pressure to be applied to it. The sealing ring is in one piece, of a polymer material.</p> |
