A limited stroke hydraulic actuator which may be located in the structure of a steered axle in a shallow blind bore. The piston which may be slidably received in the bore is displaced by an adjustable protrusion secured to the steering system. Displacement of the piston causes hydraulic fluid to flow through an orifice from one side to the other. Resistance to flow of fluid through the orifice damps the motion of the piston and consequently the steering system. A spring returns the piston to an initial position when the steering system is removed from end of travel position.

A damper for absorbing the impact of a steering knuckle against a structural member of a steering axle comprising; a close ended bore formed integrally within said structural member having a bottom portion and a cylindrical portion; a top member having an opening defined therein disposed in said bore and sealingly connected to said cylindrical portion of said bore; a piston disposed in said bore and having a flange portion sealingly received in said cylindrical portion; said piston having a rod portion sealingly received in said opening defined in said top member; said top member, said cylindrical portion of said bore and said piston forming a first annular working chamber; said bottom and cylindrical portion of said bore and said piston forming a second annular working chamber; a fluid disposed in said first and second chambers; said flange portion of said piston having a first fluid flow orifice formed therein to enable fluid flow between said first and said second chambers; a spring imparting resilient force on said piston to define an initial position; and a stop member disposed on said steering knuckle for engaging said piston and displacing said piston from said initial position to a second position whereby the impact of said stop member against said structural member is damped by the forces encountered as fluid flows between said first and second chambers.
