[Continued on next page] (54) Title: A FOAM DISPENSER 10 (57) Abstract: A foam assembly connectable to a liquid container includes a 16 main pump body, a resiliently deformable piston dome, an air chamber, a li 3 quid chamber, a mixing zone and a porous member. The main pump body has an exit nozzle with the porous member therein. The air chamber and the 35 liquid chamber are each defined by the piston dome and the main pump - -28 body. The liquid chamber has a liquid inlet valve and a liquid outlet valve. 1 The mixing zone is in flow communication with the air chamber and the li quid chamber. The volume of the air chamber and the liquid chamber are 66 each dependent on the position of piston dome and during an activation 33 stroke the piston moves from the at rest position to the depressed position 20- and responsively the volume of the air chamber and the volume of the liquid 6 -chamber are reduced.
