ABSTRACT:
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.
