Abstract

Amortiguador con pistón con filtro de alta velocidad. Se refiere a un sistema que aporta una reducción de carga hidráulica en el amortiguador cuando el pistón (3) se desplaza a una velocidad suficientemente elevada. En el cilindro (1) que constituye la carcasa del amortiguador, se ha previsto un tubo separador de presiones a de cámaras, con una cámara de tracción y otra de compresión. En este tubo separador se dispone de forma deslizante un pistón auxiliar (7) con un chaflán (11) y que puede desplazarse en contra de un muelle (8) que lo mantiene impulsado hacia un tope (9) y que en función de su posición respecto a un orificio de pasa (10) del tubo separador regula dicho paso de fluido de una cámara a la otra. Se prevé en el tubo separador un orificio (12) que colabora con otro orificio (13) del pistón deslizante (7) para proporcionar una bajada de presión, evitándose así generar alta presión y amortiguamiento cuando la velocidad del amortiguador es elevada.Shock absorber with piston with high speed filter. It refers to a system that provides a reduction in hydraulic load on the shock absorber when the piston (3) travels at a sufficiently high speed. In the cylinder (1) that constitutes the housing of the shock absorber, a pressure separator tube is provided with chambers, with a traction chamber and a compression chamber. In this separator tube an auxiliary piston (7) with a chamfer (11) is slidably arranged and can be moved against a spring (8) that keeps it driven towards a stop (9) and that depending on its position with respect to a through hole (10) of the separator tube regulates said fluid passage from one chamber to the other. A hole (12) is provided in the separator tube that collaborates with another hole (13) of the sliding piston (7) to provide a pressure drop, thus avoiding generating high pressure and damping when the speed of the damper is high.
