The invention is in the field of aircraft shock struts, of the type having a piston cylinder and a piston head, for slowing movement of an aircraft structure toward the ground, particularly during landing or take-off. The invention provides a more constant change in pressure across the piston head, that is generally independent of piston head speed, relative to the prior art. The piston head has a damped valve poppet received within the piston head moveable from a first position wherein the damped valve poppet covers a pressure relief orifice to a second position that uncovers a pressure relief orifice, thereby providing a more constant change in pressure across the piston head.
