| 摘要 |
The invention concerns a fluid product dispensing device comprising a reservoir (1) containing the fluid product and a propellant gas, a metering valve (2) mounted on said reservoir, including a metering chamber and a check valve (3) mobile between an idle position and a dispensing position, and an automatic triggering system, preferably actuated by the user's inhalation, for actuating said check valve, said triggering system including an actuating element (10) adapted to displace either the check valve (3) or the reservoir (1) relative to the other, to bring the check valve (3) of the metering valve (2) in its dispensing position. The invention is characterized in that the device comprises in combination a braking system (60, 70) which co-operates with the reservoir (1) or the check valve (3) of the metering valve (2) to slow down the displacement of the check valve (3) towards its dispensing position, when the device is actuated, and a check valve release system, automatically actuated when the check valve reaches its dispensing position, and which returns said check valve (3) into its idle position independently of the position of said actuating element (10). |
