Abstract : The patent relates to a recoil mechanism whereby a self-locking hydraulic piston and cylinder arrangement interposed between a stationary and a movable member is provided with a slidable poppet valve in the heat of the piston. The valve is normally spring biased to a fully open position to permit a slightly restricted passage of hydraulic fluid through the piston head during the movement of the pivotal member relative to the stationary member. However, when the poppet valve is subjected to a differential pressure in excess of the spring bias threagainst, it is automatically actuated to block the passage of the hydraulic fluid through the piston heat thereby preventing further relative movement between the piston and cylinder which then acts as a rigid link between the movable and stationary members.
