A dispenser includes a housing holding an assembly, including a liquid reservoir, a pump for dispensing the fluid product, and an outlet nozzle. The pump includes a liquid chamber for containing a dose of the liquid product and a pressurizing device which allows liquid product to be drawn into or expelled from the liquid chamber. The dispenser further includes a shunting chamber including a first aperture allowing flow access to the reservoir, a second aperture allowing flow access to the outlet nozzle, and a third aperture allowing flow access to the liquid chamber. The third aperture is disposed off-axis with respect to the first and second apertures. The shunting chamber further includes a mechanically actuated governing device that has two states, one defining a flow path between the first and third apertures and one defining a flow path between the third and second apertures.
