ABSTRACT:
High frequency shock absorber/accelerator built in at any or both end of conventional air cylinder that includes piston moving axially inside cylinder body and sealed against inner surface of body by sealing structure. Cylinder piston rod protrudes outside thru cylinder front-end block Shock absorber/accelerator comprises piston with sealing structures moving axially in inner chamber, which communicates with outer chamber thru aperture(s). Air cylinder piston meets the protruded rod of the shock absorber/accelerator piston and starts to move it thus pushing volume of compressed air through provided aperture from inner chamber to outer chamber. Piston sealing structures seal air coming through the aperture thereby isolating compressed air in the outer chamber from the inner chamber. Compressed air coming through the open venting valve forces pistons to move in opposite direction. Then, shock absorber/accelerator aperture opens and compressed air rushes back from the outer to the inner chamber for powerful acceleration.
