Abstract

Válvula amortiguadora para un amortiguador de vibraciones, que comprende un cuerpo de la válvula amortiguadora que presenta al menos un canal de alimentación para cada dirección de circulación, que une un lado superior y un lado inferior del cuerpo de la válvula amortiguadora entre sí, una placa de la válvula sobre una superficie de asiento de la válvula, pudiendo la placa de la válvula levantarse de la superficie de asiento de la válvula, una estrangulación previa dentro del recorrido de unión entre el lado superior y lado inferior de la válvula amortiguadora, en la que la sección transversal de la estrangulación previa está definida por la anchura de una abertura de admisión del canal de alimentación y la distancia radial media entre una arista que determina el contorno de la placa de la válvula y la abertura de admisión. (Figura 1ª)Damper valve for a vibration damper, comprising a damper valve body having at least one supply channel for each direction of circulation, connecting a top side and a bottom side of the damper valve body to each other, a plate of the valve on a valve seating surface, the valve plate being able to lift from the valve seating surface, a previous throttling within the connection path between the upper and lower side of the damper valve, in the that the cross section of the pre-throttle is defined by the width of a supply channel intake opening and the average radial distance between an edge determining the contour of the valve plate and the intake opening.
