Abstract
A control valve includes a valve member shaped for engagement with a seating which is defined about a flow passage. The valve member is movable between the open and closed positions by an actuator. Formed in the valve member is a blind drilling in which is located a plunger engageable with a fixed reaction surface external of the valve member. The inner end of the drilling communicates with a passage which communicates with the flow passage. The valve member is slidable in a bore which adjacent the seating is of enlarged diameter to define a recess which communicates with a further flow passage.
