Filed: 1989-06-28
Granted: 1993-05-11
Abstract: ABSTRACT OF THE DISCLOSURE The present invention provides a system for transmitting a biasing force created by a force generating component to a load remote from the force component.  The system includes a first elongated flexible element having a first end and a second end, the first end of the first flexible element being connectable to the force generating component, and a second elongated flexible element having a first end and a second end, the first end of the second flexible element being connectable to the load.  A force modifying member rotatable about a fixed axis is provided and includes first and second outwardly facing surfaces of predetermined lengths which curve about the axis.  The second ends of the elongated flexible elements are connected respectively to the first and second surfaces at one end of the surface, wherein the flexible elements are operable to be wound or unwound on the respective surfaces as the member rotates about the axis.          The first flexible element produces a force moment about the axis in a first direction biasing the force modifying member into rotation in the first direction.  The second element exerts a resultant biasing force on the load.  The first and second surfaces are dimensioned such that rotation of the member about the axis in the first direction causes one of the elements to be wound onto its respective surface as the other element is unwound from its respective surface to vary the force moments about the axis, to render the biasing force on the load generally more uniform.

Abstract: DYNAMIC SEAL ARRANGEMENT FOR IMPELLER PUMP               ABSTRACT OF THE DISCLOSURE         An impeller pump including a housing defining a seal cavity having a shaft rotatably mounted therein, and an expeller to pump fluid from the seal cavity.  A dynamic seal provides a fluid tight seal between the housing and the shaft.  The seal comprises an axially movable primary seal ring which rotates with the shaft and a mating stationary seal ring, both rings disposed annularly of the shaft and each defining a generally radial sealing face adapted to seal against the other.  Biasing means urge the primary seal ring into sealing engagement with the mating seal ring.  The radial face of the mating seal ring defines a plurality of spiral grooves and a sealing dam area which is at the periphery of the ring exposed to high  pressure.  When the pump is not operating, the seal ring faces contact one another and the dam provides a seal against the opposing face.  When the pump is operating, the primary seal ring rotates with the shaft and the grooves create a pumping action to pump air between the faces causing the primary seal ring to lift away from the mating seal ring to prevent wear and avoid undue heat generation.
