Abstract:
A float valve assembly includes a cylindrical housing defining an inner flow path and a check valve is positioned within the housing and movable between an open position, where uphole and downhole fluid flow through the inner flow path is allowed, and a closed position, where uphole fluid flow is prevented while downhole fluid flow is allowed. An activation member is movably positioned within the housing between a first position, where the activation member holds the check valve in the open position, and a second position, where the activation member moves axially and out of engagement with the check valve. A drag body is coupled to the activation member and fluid flow in the downhole direction generates a drag force on the drag body that places an axial force on the activation member to move the activation member to the second position.

Claim (Index 2):
The float valve assembly of  claim 1 , wherein the check valve is a flapper-type check valve that includes a flapper pivotably coupled to the check valve, and wherein the activation member in the first position engages and holds the flapper in the open position and disengages the flapper upon moving to the second position.
