Abstract:
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; and a 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.
