Abstract

Dispositivo (6) tensionatore, in cui un organo (8) mobile atto a cooperare con una catena (5) di una trasmissione (1) รจ controllato da un attuatore (11) lineare provvisto di un primo corpo (13) atto ad essere mantenuto in una posizione fissa rispetto alla catena (5), e di un secondo corpo (21) mobile rispetto al primo corpo (13) sotto la spinta di una molla (27) interposta tra i corpi (13) (21) stessi; l'attuatore (11) essendo, inoltre, provvisto di un ulteriore corpo (24) interposto tra la molla (24) ed il secondo corpo (21), e di un gruppo (28) di blocco unidirezionale atto a cooperare con il secondo corpo (21) per impedire un movimento del secondo corpo (21) stesso in un senso opposto a quello di spinta della molla (27); il gruppo (28) di blocco presentando un elemento (29) mobile accoppiato con gioco assiale (9) alla molla (27) ed al secondo corpo (21).[Fig. 1].Tensioner device (6), in which a mobile member (8) adapted to cooperate with a chain (5) of a transmission (1) is controlled by a linear actuator (11) provided with a first body (13) adapted to be maintained in a fixed position with respect to the chain (5), and with a second body (21) movable with respect to the first body (13) under the thrust of a spring (27) interposed between the bodies (13) (21) themselves; the actuator (11) also being provided with a further body (24) interposed between the spring (24) and the second body (21), and with a unidirectional blocking unit (28) adapted to cooperate with the second body (21) to prevent movement of the second body (21) itself in a direction opposite to that of pushing the spring (27); the locking unit (28) having a mobile element (29) coupled with axial play (9) to the spring (27) and to the second body (21). [Fig. 1].
