Abstract
The disclosure relates to a downhole activation assembly for activating a downhole component of a downhole tool positionable in a wellbore penetrating a subterranean formation. The activation assembly includes a housing operatively connectable to the downhole tool, a piston slidably positionable in the housing with a chamber defined therebetween, and a valve. The piston has a flow channel therethrough. The valve is positionable about the flow channel of the piston, the valve comprising a fixed plate and a rotatable plate. The rotatable plate is movable about the fixed plate to define a variable bore to selectively restrict flow through the flow channel and to vary pressure about the piston whereby the piston is selectively moved to shift the downhole component between activation positions.
