Abstract (en)
[origin: WO2022117961A1] Device for dispensing a fluid product, comprising a reservoir (1) containing the fluid product and a metering valve (10) comprising a valve body (11) containing a metering chamber (30), a valve (20) sliding axially in the valve body (11) between an idle position and a dispensing position in order to dispense the contents of the metering chamber (30), the valve (20) being biased towards its idle position by a valve spring (12), the reservoir (1) containing a follower piston (5) and a piston spring (6) which axially biases the follower piston (5) towards the metering valve (10), the follower piston (5) being suitable for axially sliding in the reservoir (1) in a sealed manner after each actuation to compensate for the volume of each dispensed dose.
