Abstract
A downhole valve () comprises a housing and first and second sleeve assemblies (and) mounted within the housing () and defining an axial pocket () therebetween, wherein the first and second sleeve assemblies are arranged to be moved axially relative to each other. A valve member () is mounted within the axial pocket and is rotatable about a rotation axis in response to relative axial movement of the first and second sleeve assemblies from a closed position in which fluid flow through the downhole valve is restricted towards an open position in which fluid flow through the downhole valve is increased or permitted. An interface arrangement () axially extends from the second sleeve assembly and engages the valve member via an interface mechanism for converting relative axial movement of the first and second sleeve assemblies to rotation of the valve member.
