Throttling valve with adjustable stiffness and associated shock absorber

摘要

(4). The invention concerns a damper valve (1) comprising at least an elastic washer (11) designed to close at least a damping fluid flow orifice (4) located in a base (10) of the valve (1). The invention is characterised in that it comprises means for adjusting the stiffness of the valve capable of adjusting the resistant force developed by the washer (11) countering the fluid flow into the orifice (4).
