Abstract
Disclosed herein are embodiments of a valve assembly for providing selective flow communication between a plurality of fluid flow conduits. The valve assembly may comprise two valve members disposed coaxially in fluidly sealing contact and relatively rotatable to provide valving action of at least two port tracks. At least one valve member may comprise a fluid pressure loading means, and the fluid pressure loading means may span at least two port tracks. The valve assembly may further comprise a drive means for driving relative rotation of the valve members in order to enable cycled interconnection and fluid flow through the fluid flow conduits.
Claims10
A valve assembly for providing selective flow communication between a plurality of fluid flow conduits comprising:
- two valve members disposed coaxially in fluidly sealing contact and relatively rotatable to provide valving action of at least two port tracks, where at least one valve member comprises pressure-balance means, and the pressure balance means spans at least two port tracks, and
- drive means for driving relative rotation of the valve members in order to enable cycled interconnection and fluid flow through the plurality of fluid flow conduits.
A valve assembly for providing selective flow communication between a plurality of fluid flow conduits comprising:
- two valve members disposed coaxially in fluidly sealing contact and relatively rotatable to provide valving action of at least two port tracks, where at least one valve member comprises a pressure balance piston, and the pressure balance piston spans at least two port tracks, and
- a drive shaft for driving relative rotation of the valve members in order to enable cycled interconnection and fluid flow through the plurality of fluid flow conduits.
A valve assembly for providing selective flow communication between a plurality of fluid flow conduits comprising:
- two valve members disposed coaxially in fluidly sealing contact and relatively rotatable to provide valving action of at least two port tracks, wherein
- each of the at least two port tracks is located on a pitch circle and at least two of the pitch circles has a different diameter, and
- at least one valve member comprises pressure-balance means, and the pressure balance means spans at least two port tracks;
- and
- drive means for driving relative rotation of the valve members in order to enable cycled interconnection and fluid flow through the plurality of fluid flow conduits.
