Abstract
Pistón de control para amortiguadores hidráulicos. En los amortiguadores hidráulicos convencionales existe un pistón (2) conectado a un vástago (3) de accionamiento para definir dos cámaras, una de tracción (4) y otra de compresión (5), inundadas de fluido. Hay amortiguadores en los que existe un sistema similar al pistón, incorporando un soporte-válvula que divide la cámara (5) en dos partes. Acorde con la invención el pistón incluye una pieza rígida (12) axial a un tubo separador de presiones que normalmente es el vástago y operativamente dispuesta de forma deslizante en dicho tubo estando impulsada su posición de cierre mediante un resorte (14) teniendo dicha (12) un extremo activo de configuración en chaflán (13) para ofrecer una geometría variable y en consecuencia una sección variable de paso de una cámara a la otra, en su desplazamiento respecto del tubo separador de presiones.Control piston for hydraulic shock absorbers. In conventional hydraulic shock absorbers there is a piston (2) connected to a drive rod (3) to define two chambers, one of traction (4) and another of compression (5), flooded with fluid. There are shock absorbers in which there is a piston-like system, incorporating a valve support that divides the chamber (5) into two parts. According to the invention, the piston includes a rigid part (12) axial to a pressure separator tube which is normally the rod and operatively arranged slidably in said tube, its closing position being driven by a spring (14) having said (12 ) an active end of chamfer configuration (13) to offer a variable geometry and consequently a variable section of passage from one chamber to the other, in its displacement with respect to the pressure separator tube.
