Abstract

Il conducente, mediante la leva (1) del dispositivo di registro staffato a telaio che trasmette su cavo di acciaio (2), fa ruotare una bussola (3) in una seconda bussola (4) del canotto (5). Alla prima bussola (3) è ancorato il primo capo di una molla a fascia (6) il cui altro capo è collegato alla bussola (4) rigida. Mediante il detto movimento si determina l'avvitamento o lo svitamento di un'asta (7) entro una bussola (9) che attua il caricamento o lo scaricamento di una molla (10) impostata tra un battente (11) ed un pistoncino (12) forato alla cui estremità (13) è interposto un anello di plastica (14) fungente da otturatore Variabile. Il caricamento o lo scaricamento della molla (10) agevola il contrasto per il passaggio forzato o meno del flusso dell'olio da una camera (15) all'altra (16). Mediante la leva dentata (1) del blocco di regolazione (26) con staffa (27) di supporto a telaio del velocipede, secondo una prefissata scala di registro, si opera la regolazione dell'effetto ammortizzante mediante la bussola (3) tramite la valvola (28) per l'immissione o meno dell'aria operante la compressione dell'olio.
