<p>The invention relates to a foam-dispensing device (1) comprising a pump assembly (3) , which pump assembly comprises a liquid pump (4) and an air pump (5) , which can be actuated by means of a common operating element (6) , which can be moved with respect to a fixed part of the pump assembly, for delivering a liquid and air, respectively, to a common dispensing passage (15) where the liquid and the air are combined to form a foam, the operating element being able to perform a stroke in order to actuate the liquid pump and the air pump. The invention is characterized by the fact that the foam-dispensing device is designed to deliver, during a first part of the stroke (51) , both liquid from the liquid pump and air from the air pump to the dispensing passage in order to form a foam, and to deliver, during a second part of the stroke (52) , only air from the air pump to the dispensing passage.</p> |
