Abstract

Damper with piston with high speed filter.It refers to a system that supports a reduction in the hydraulic load of a damper when the piston (3) moves at a sufficiently high speed.The cylinder (1) that constitutes the chassis of the damper is equipped with a pressure or chamber separator tube. In this separator tube an auxiliary piston (7) is placed in a moving manner and with a chamfer (11) that can be moved against a spring (8) that keeps it moving towards a stopper (9) and that, depending on its position with respect to a pass-through hole (10) of the separator tube, regulates said passage of liquid from one chamber to another.The separator tube will contain a hole (12) that collaborates with another hole (13) of the moving piston (7) to provide a decrease in pressure, thus preventing the generation of high pressure and dampering when the speed of the damper is high.
