The cam mechanism (43, 55) defines a maximum cam stroke that is greater than the maximum rod stroke; and a resilient mechanism (56) acts axially to compensate for the extra amount of the maximum cam stroke and thus allow it to be followed so as to guarantee that the rod performs its maximum stroke in full. ## Claims ### Claim 1 A fluid dispenser, comprising: a fluid reservoir; a dispenser member through which the fluid is delivered, the dispenser member comprising a body and an actuator rod that is axially movable down and up relative to the body over a maximum rod stroke; a dispenser orifice where a user may recover the dispensed fluid; a rotary actuator member that the user can turn about its own axis; a transmission member that is engaged both with the dispenser member and also with the rotary actuator member; and cam means that are formed by the rotary actuator member and by the transmission member for transforming turning of the rotary actuator member into an axial movement of the actuator rod or of the body; the dispenser being characterized in that: the cam means define a maximum cam stroke that is greater than the maximum rod stroke; and resilient means act axially so as to compensate for the extra amount of the maximum cam stroke and thus allow it to be followed so as to guarantee that the rod performs its maximum stroke in full. ### Claim 2 (depends on 1) A dispenser according to claim 1, wherein the cam means comprise at least one cam path of axial height that varies, and at least one cam follower that follows the respective cam path. ### Claim 3 (depends on 1) A dispenser according to claim 1, wherein the transmission member comprises a central cap that is engaged with the actuator rod, and a cam ring that defines at least one cam path of axial height that varies. ### Claim 4 (depends on 3) A dispenser according to claim 3, wherein the resilient means are formed by the transmission member. ### Claim 5 (depends on 4) A dispenser according to claim 4, wherein the cam ring is connected to the central cap via a plurality of flexible bridges forming the resilient means and/or the cam ring is elastically deformable so as to form the resilient means. ### Claim 6 (depends on 3) A dispenser according to claim 3, wherein the rotary actuator member includes a plurality of profiles forming cam followers that come into engagement with the cam paths of the cam ring and that follow them. ### Claim 7 (depends on 3) A dispenser according to claim 3, wherein the rotary actuator member comprises a rotary actuator ring that a user can grip, and a collection dish in which the user can recover the fluid that has been dispensed. ### Claim 8 (depends on 7) A dispenser according to claim 7, wherein the rotary actuator ring does not move axially, and the collection dish is elastically deformable so as to follow the axial movement of the actuator rod. ### Claim 9 (depends on 8) A dispenser according to claim 8, wherein the collection dish is fastened to the central cap of the transmission member, which central cap advantageously forms a connection bushing that is connected to the actuator rod, and an endpiece that is connected to the collection dish. ### Claim 10 (depends on 1) A dispenser according to claim 1, wherein the resilient means are formed by the rotary actuator member. ### Claim 11 (depends on 1) A dispenser according to claim 1, wherein the transmission member is engaged with the fluid reservoir at its bottom.
