Abstract

A fluid product dispenser comprising a tank and a metering device mounted on the tank, the metering device having a chamber defining an inlet, an abutment, an outlet and a sealing seat, the abutment separated from the sealing seat by a stroke distance; a valve movable inside the chamber over the stroke defined between a rest position, in which the valve is biased by a return force towards the abutment, and an end position, in which the valve is selectively urged onto the sealing seat against the return force by the fluid flowing in the chamber from the inlet to the outlet; and a mechanism for adjusting the stroke of the valve capable of adjusting the stroke distance separating the abutment from the sealing seat. The adjustment mechanism is located in the fluid tank, so that they are inaccessible and cannot be actuated from outside the fluid product dispenser.

Dependent claims

A fluid product dispenser comprising a reservoir for fluid product and a metering device for fluid product mounted on the fluid reservoir, the dispensing device comprising:

a chamber defining an inlet, an abutment, an outlet and a sealing seat, the abutment being separated from the sealing seat by a stroke distance,
a shutter which can be displaced in the chamber over a stroke defined between a rest position, in which the shutter is biassed towards the abutment by a restoring force, and an extreme position, in which the shutter is selectively urged towards the sealing seat against the restoring force by the fluid circulating in the chamber from the inlet towards the outlet,
means for adjusting the stroke of the shutter which are capable of adjusting the stroke distance separating the abutment from the sealing seat,
the adjustment means is located inside the dispenser in a manner such that they are inaccessible from the exterior of the fluid product dispenser.
