A fluid dispenser comprising: at least one fluid reservoir (1a, 1b) provided with an opening (11a, 11b); at least one fluid dispenser member (3a, 3b), such as a pump or a valve, comprising a body (31a, 31b) that is mounted in stationary manner on the opening of the reservoir, and an actuator rod (32
A fluid dispenser comprising: at least one fluid reservoir (1a, 1b) provided with an opening (11a, 11b); at least one fluid dispenser member (3a, 3b), such as a pump or a valve, comprising a body (31a, 31b) that is mounted in stationary manner on the opening of the reservoir, and an actuator rod (32a, 32b) that is axially movable down and up along an axis X over a stroke; a pusher (9) that is axially movable down and up along an axis Y so as to move said at least one actuator rod (32a, 32b) axially; and the dispenser being characterized in that it further comprises stroke-variation means (8) for varying the stroke of the actuator rod, said means being disposed between the pusher (9) and said at least one actuator rod (32a, 32b), so as to vary the stroke of the stem.

1. A fluid dispenser comprising: at least one fluid reservoir provided with an opening;at least one fluid dispenser member that is a pump, comprising a body that is mounted in stationary manner on the opening of the reservoir, and an actuator rod that is axially movable down and up along an axis X over a stroke;a pusher that is axially movable down and up along an axis Y so as to move said at least one actuator rod axially; anda stroke-variation mechanism that varies the stroke of the actuator rod so as to dispense one or more varying doses of fluid between no stroke that delivers no dose and a maximum stroke that delivers a maximum dose, said stroke-variation mechanism disposed between the pusher and said at least one actuator rod;the stroke-variation mechanism comprises at least one movable bearing path that is adapted to bear against said at least one actuator rod, the path defining axially-offset bearing zones that can, by moving the path, be positioned axially above said at least one actuator rod;the stroke-variation mechanism further comprises a rotary ring that turns about an axis Z that is parallel to, or coincides with, the axis Y, the ring turning about the at least one actuator rod. 2. A device according to claim 1, in which the rotary ring is received in the pusher that does not move relative to said at least one actuator rod. 3. A device according to claim 1, in which said at least one path extends in a circular arc centered on the axis Z. 4. A device according to claim 1, in which the path slopes in such a manner as to form a ramp. 5. A device according to claim 1, in which the path is stepped in such a manner as to form a riser that is axially offset. 6. A device according to claim 1, in which the ring includes an actuator member that is accessible through a window formed by the pusher. 7. A device according to claim 1, in which the ring includes locking means that are adapted to block the pusher at rest. 8. A device according to claim 1 comprising two reservoirs, two dispenser members, a pusher, and two respective bearing paths for the two actuator rods. 9. A device according to claim 8, in which the axially-offset bearing zones of the paths extend with axial slopes that are generally opposite, so that the strokes of the two rods vary in opposite manners while the pusher is being actuated. 10. A device according to claim 8, in which the bearing paths are formed by the rotary ring that turns about the axis Z that extends mid-way between the two axes X of the actuator rods, the paths extending in circular arcs centered on the axis Z. 11. The device according to claim 1, wherein the at least one fluid dispenser member is a pump or a valve. 12. A fluid dispenser comprising: at least one fluid reservoir comprising an opening;at least one fluid dispenser member that is a pump comprising a body mounted in stationary manner on the opening of the reservoir, and an actuator rod axially movable down and up along an axis X over a stroke;a pusher axially movable down and up along an axis Y so as to move the at least one actuator rod axially;means for varying the stroke of the actuator rod so as to dispense one or more varying doses of fluid between no stroke that delivers no dose and a maximum stroke that delivers a maximum dose, the means for varying the stroke of the actuator rod disposed between the pusher and the at least one actuator rod;the means for varying the stroke of the actuator rod is rotatable at least in part about an axis Z parallel to, or coinciding with, the axis Y. 13. The fluid dispenser according to claim 12, wherein the means for varying the stroke of the actuator rod comprises bearing paths at different heights in the Y axis direction and configured to be selectively positioned above the actuator rod, each bearing path defining a different stroke length of the actuator rod.
