<p>Self Adjusting Shock Absorber A self adjusting shock absorber comprising a cylinder and a shock absorbing piston movable in the cylinder and having a shaft extending externally of the cylinder. A reservoir is associated with one end of the cylinder. A flow passage is provided in the shock absorbing piston. A pump comprises a cylinder formed in the shock absorbing piston, and having a position sensing bleed orifice intermediate the ends thereof. A pump piston is fixed to the shock absorbing cylinder and is operable in said pump cylinder. The piston functions when in a position on one side of the position sensing bleed orifice to produce a pump "down" cylinder and when operating on the other side of the position sensing bleed orifice to provide a pump "up" cylinder. The pump piston has a first passage providing selective communication between the shock absorbing cylinder and one end of the pump cylinder, and a second passage providing communication between the shock absorbing cylinder and the other end of said pump cylinder. Check valves are associated with said passages.</p> |
