Abstract
Abstract A three-way valve, having (1) a unitary balanced plug, (2) a pair of stacked cages each having an inverted cone-shaped end for engaging separate wedge-shaped ring seals to move them outwardly and into sealing contact with the valve body and (3) a unique ring member to apply a biasing force on the cage to permit the caged parts to expand without becoming distorted when the temperature of the fluid passing through the valve is increased or decreased and to also maintain the ring seals in fluidtight sealing contact with the valve body before, during and after the changes in temperature of the fluid.

Total Claims: 11
Claim 1
Independent Claim
258 words
A balanced three-way valve comprising a hollow body having an inlet and two outlet passageways, a cage means positioned within and in contact with said body at a location that is between the inlet and outlet passageways and having a pair of spaced-apart seating surfaces thereon, said cage means having a peripheral beveled end portion and a resilient seating ring forming a seal between the beveled end of the cage means and a body portion that is adjacent thereto, the outer periphery of the seating ring having a surface portion that is at a different inclined angle than the angle forming the beveled end of the cage, a means to jointly move said beveled end of the cage means into compressed engagement with the seating ring and the ring into compressed fluidtight engagement with said body with which the ring is in contact, a unitary plug mounted for movement into engagement with one or the other of the said seating surfaces to provide a way of diverting a flow of fluid from said inlet to a selected one of said outlet passageways, said plug having passageways extending between its top and bottom surfaces to allow the pressure of the fluid to be simultaneously applied to these surfaces and along equal areas thereof to maintain the plug in a balanced condition when said plug is in either one of said fluid flow diverting positions and while drops and increases occur between the pressure of the fluids that are passing into the inlet and flowing out of the outlet passageways.

Dependent Claim
188 words
The balanced three-way valve defined in claim 1 wherein the seating ring is of a wedge-shaped cross section and is loosely positioned within an inner wall of the body at a position that is immediately under the beveled end portion of the cage means, said beveled end portion of the cage means being positioned to form an inverted cone surface on a periphery of the cage means inclined at said different angle than the inclined surface formed on said wedge-shaped seating ring, and wherein said means is employed to move the bevelEd peripheral end portion of the cage means into peripheral compressed engagement with said inclined surface on the wedge-shaped seating ring to thereby provide a fluidtight seal between the external peripheral end portion of the cage means and a wall of the body adjacent thereto and wherein the angular difference that exists between the peripheral beveled end of said cage means and the angle at which said inclined surface is formed on the wedge-shaped seating ring, enables the movable means to force the wedge-shaped seating ring in an outward direction against said inner surface of the body.
Claim 6
Dependent Claim
149 words
The balanced three-way valve defined in claim 1 wherein the seating ring is of a resilient wedge-shaped cross section and is loosely positioned within a wall of the body and at a position that is immediately under a peripheral end portion formed by said beveled end of the cage means, said peripheral end portion of the cage means being inclined at a different angle than an inner inclined annular surface of said wedge-shaped ring, and said cage moving means is employed to move said beveled end portion of the cage means into peripheral compressed engagement with the inclined surface of the resilient wedge-shaped ring to thereby provide a fluidtight seal between the external peripheral end portion of the cage and a wall of the body and wherein said beveled shaped end of the cage and said inclined surface of the wedge differs from one another by substantially one degree.
Claim 7
Dependent Claim
