ABSTRACT:
A fluid dispenser device including a reservoir containing the fluid and a propellant; a metering valve mounted on the reservoir and including a metering chamber, and a valve member that is movable between a rest position and a dispensing position; and an automatic trigger system, the trigger system including an actuator element to displace one of the valve member and the reservoir relative to the other so as to bring the valve member into its dispensing position. The device also includes a brake system which co-operates with the reservoir or the valve member to slow down displacement of the valve member towards its dispensing position while the device is being actuated, and a valve-member release system that is actuated automatically when the valve member reaches its dispensing position, and which returns the valve member to its rest position independently of the position of the actuator element.
