Abstract
A gland seal arrangement for effecting a fluid seal between two relatively movable parts wherein the loading applied to an annular sealing member in contact with such parts is derived from a coaxially arranged, sleeve-like thrust member sensitive to the pressure of the fluid being sealed so that with increasing fluid pressure the loading applied to the sealing member is correspondingly increased.
Claims10
A gland seal arrangement for providing a fluid-tight seal between two relatively movable parts (12, 17), the said arrangement comprising an annular sealing member (11a) for disposal between said parts (12, 17) in sealing contact therewith, the said member (11a) being axially locatable in one said part (12, 17), and a thrust member (11f) arranged to act axially upon the said sealing member (11a), the said thrust member (11f) having a face (11f") for exposure to the pressure of the fluid being sealed and being adapted, when subjected to such pressure, to urge the sealing member into such sealing contact.
