Abstract

Dispositivo amortiguador hidráulico de aguja, del tipo que incluye una cavidad primaria llena de fluído hidraúlico y una cavidad secundaria igualmente llena de fluído hidraúlico y asociada, por otro lado, a un elemento comprensible, estando provisto dicho amortiguador de una aguja cilíndrica destinada a deslizarse, con una holgura suficiente precisamente para el deslizamiento, en el surtidor que une las dos cavidades, caracterizado porque dicha aguja está provista de medios que permiten dar un movimiento en remolino al fluído inyectado en la cavidad secundaria en el curso de la operación de amortiguación, siendo tales dichos medios que crean chorros en remolinos de direcciones alternadas en planos de secciones sucesivas a lo largo de la aguja.
