A fluid dispenser, comprising: - a fluid reservoir containing fluid under pressure; - a valve through which the fluid under pressure is driven, the valve including an internal return spring, - a dispenser head that co-operates with the valve so as to dispense the fluid through a dispenser orifice, the dispenser head comprising: - a dispenser endpiece that is connected to the valve and that defines the dispenser orifice, and a feed duct that connects the valve to the dispenser orifice, - a pusher for moving the dispenser endpiece along an actuation axis X between a rest position in which the valve is closed and a depressed position in which the valve is open, the dispenser endpiece being urged towards its rest position by the internal return spring of the valve, the dispenser head further comprising: - a limited thrust member that transmits the axial thrust force from the pusher to the dispenser endpiece so as to move it axially over a stroke that is limited, but that is sufficient to open the valve, - a thrust release member that acts on the limited thrust member, releasing the dispenser endpiece from the axial thrust force from the pusher, as transmitted by the limited thrust member, at the end of the limited axial stroke, so that the dispenser endpiece returns to its rest position and the valve closes, characterized in that the dispenser endpiece includes an axial bearing collar, and the limited thrust member includes at least one axial bearing profile that selectively comes into engagement with the axial bearing collar so as to entrain the dispenser endpiece over its limited axial stroke. - a fluid reservoir containing fluid under pressure; - a valve through which the fluid under pressure is driven, the valve including an internal return spring, - a dispenser head that co-operates with the valve so as to dispense the fluid through a dispenser orifice, the dispenser head comprising: - a dispenser endpiece that is connected to the valve and that defines the dispenser orifice, and a feed duct that connects the valve to the dispenser orifice, - a pusher for moving the dispenser endpiece along an actuation axis X between a rest position in which the valve is closed and a depressed position in which the valve is open, the dispenser endpiece being urged towards its rest position by the internal return spring of the valve, - a dispenser endpiece that is connected to the valve and that defines the dispenser orifice, and a feed duct that connects the valve to the dispenser orifice, - a pusher for moving the dispenser endpiece along an actuation axis X between a rest position in which the valve is closed and a depressed position in which the valve is open, the dispenser endpiece being urged towards its rest position by the internal return spring of the valve, - a limited thrust member that transmits the axial thrust force from the pusher to the dispenser endpiece so as to move it axially over a stroke that is limited, but that is sufficient to open the valve, - a thrust release member that acts on the limited thrust member, releasing the dispenser endpiece from the axial thrust force from the pusher, as transmitted by the limited thrust member, at the end of the limited axial stroke, so that the dispenser endpiece returns to its rest position and the valve closes, characterized in that the dispenser endpiece includes an axial bearing collar, and the limited thrust member includes at least one axial bearing profile that selectively comes into engagement with the axial bearing collar so as to entrain the dispenser endpiece over its limited axial stroke.
