Abstract
An adjustable shock absorber for applying a force to a moving member so as to decelerate the member. The present invention provides a cylindrical outer tube having a plurality of circular, angular grooves formed in the inner surface of the tube. A cylindrical inner tube is rotatably disposed within the outer tube. A piston is slidably disposed within the inner tube and is engageable with the moving member. The piston moves between a compressed position and an extended position. The inner tube has a plurality of apertures extending therethrough and fluidly communicatable with the grooves in the outer tube. A screw thread is formed in the outer surface of the inner tube and is fluidly communicatable with the grooves in the outer tube. The inner tube and the outer tube rotate with respect to each other to adjust the level of fluid communication between the rearward end and the forward end of the shock absorber to adjust the level of force applied to the moving member. The use of the screw thread on the inner tube increases the efficiency of the manufacturing process as opposed to conventional processes.
