Patent ID: 7299800

Claim:
A fluid dispenser device comprising: a reservoir ( 1 ) containing the fluid and a propellant; a metering valve ( 2 ) mounted on said reservoir and comprising a metering chamber, and a valve member ( 3 ) that is movable between a rest position and a dispensing position; and an automatic trigger system, actuated by the user inhaling in order to actuate said valve, said trigger system including an actuator element ( 10 ) adapted to displace one of the valve member ( 3 ) and the reservoir ( 1 ) relative to the other so as to bring the valve member ( 3 ) of the valve ( 2 ) into its dispensing position, the device being characterized in that it includes, in combination, a brake system ( 60 , 70 ) which co-operates with the reservoir ( 1 ) or with the valve member ( 3 ) in order to slow down displacement of the valve member ( 3 ) towards its dispensing position during the entire actuation stroke while the device is being actuated, and a valve-member release system that is actuated automatically and immediately when the valve member ( 3 ) reaches its dispensing position, and which returns said valve member ( 3 ) to its rest position independently of the position of said actuator element ( 10 ).
