Claim Text:
1. A locking poppet valve comprises: a valve assembly; an actuating mechanism; a hydraulic fluid isolated from a fluid flows through the valve assembly; wherein: the valve assembly comprises a valve housing, a fluid channel, and a poppet valve; the valve housing comprises a valve body; the poppet valve comprises a valve stem and a valve spool; the valve stem being concentrically connected to the valve body; the fluid channel traversing through the valve stem; and the valve spool being slidably connected to the valve stem, wherein the hydraulic fluid acts on the valve spool; the actuating mechanism comprises an actuator housing, a piston, and a locking mechanism; the piston comprises a locking rod and an actuator spool; the actuator housing being adjacently connected to the valve housing; the poppet valve being positioned within the valve housing; the fluid channel traversing through the valve housing; the actuator housing being in fluid communication with the poppet valve through the fluid channel; the actuator housing and the fluid channel being filled with the hydraulic fluid; the locking mechanism being mechanically coupled to the actuator housing and configured to engage the locking rod; the locking mechanism comprises a ball detent locking ring and a plurality of locking balls; the ball detent locking ring being slidably positioned around the actuator housing; the plurality of locking balls traversing through the actuator housing; and the plurality of locking balls being positioned around the actuator housing adjacent to the ball detent locking ring; the piston being slidably positioned within the actuator housing; the piston being positioned adjacent to the locking mechanism; and the actuator spool being concentrically connected to the locking rod opposite the locking mechanism.
