Shock absorber with adjustable compression and rebound

An adjustable shock absorber comprising:

• an outer sliding tube having a closed end comprising attachment means for fastening to a wheel axis and an open end for telescopically mounting said inner sliding tube;
• an inner sliding tube comprising a first plug assembly at its upper end and a first elastic means positioned within its internal cavity;
• an adjustment means comprising:
• at least one adjustable screw;
• a barrel which is closed on its upper end by a second plug assembly and fastened on its lower end to said closed end of said outer sliding tube;
• and
• a piston positioned within said barrel creating an upper and lower chamber, and comprising a upper flow damper and lower flow damper which control the passage of liquid between said upper chamber and said lower chamber each said flow damper including a shim on each flow damper which will flex during compressions of variable degree and allow greater flow through the respective flow damper, thereby dampening the resultant force transferred by the shock absorber;
• and
• a support tube connected on its upper end to said first plug assembly and connected on its lower end to said piston and axially traversing said second plug assembly;
• wherein said telescopic system has at least two internal chambers arranged such that the liquid contained therein flows through at least one of said flow dampers;
• and
• wherein said upper flow damper is adjustable by means of an adjustment screw positioned axially within said support tube and which protrudes with lateral seal from said first plug assembly.
