Abstract

AN ISOLATOR SEAL COMPRISING A STATOR MEMBER (17) FOR LOCATION INTO THE STATOR OF ROTATING EQUIPMENT AND A ROTOR MEMBER (14) FOR LOCATION ONTO A ROTARY SHAFT (12) OF THE ROTATING EQUIPMENT. THESE TWO MEMBERS PROVIDE ADJACENT SURFACES (82, 83) AND A STATIC SHUT OFF DEVICE (80) COMPRISING A RESILIENT ANNULAR SEALING MEMBER (81) WHICH ENGAGES BOTH ADJACENT SURFACES WHEN THE ROTOR MEMBER IS STATIC AND DISENGAGES ONE OR MORE OF SAID ROTOR MEMBER AND STATOR MEMBER SURFACES (82, 83) WHEN THE ROTOR MEMBER IS DYNAMIC. IN ONE ASPECT OF THE PRESENT INVENTION AT LEAST ONE OF SAID SURFACES OF SAID ROTOR MEMBER AND SAID STATOR MEMBER ARE BOTH INCLINED TO THE LONGITUDINAL AXIS AT AN ANGLE GREATER OR LESS THAN 90°. IN A FURTHER ASPECT OF THE PRESENT INVENTION, THE STATIC SHUT-OFF DEVICE (80) COMPRISES A RESILIENT ANNULAR SEALING MEMBER (81) AND AN AUXILIARY MEMBER, MOVABLE BETWEEN A FIRST POSITION, WHEN THE ROTOR MEMBER IS STATIC, AT WHICH SAID AUXILIARY MEMBER COMPRESSES THE RESILIENT ANNULAR SEALING MEMBER INTO ENGAGEMENT WITH BOTH SAID SURFACES AND A SECOND POSITION AT WHICH THE COMPRESSION ON THE RESILIENT ANNULAR SEALING MEMBER IS REDUCED, WHEREBY THE RESILIENT ANNULAR SEALING MEMBER DISENGAGES ONE OR MORE OF THE ROTOR AND STATOR SURFACES WHEN THE ROTOR IS DYNAMIC.
