Abstract: A system for dispensing liquid foam, in particular a direct foam cleaning product, comprises a container for the liquid and a dispensing apparatus connected to the container. The dispensing apparatus comprises a pump comprising a pump chamber in fluid communication with the container and a piston arranged in the pump chamber, the piston and pump chamber being movable with respect to one another. An outlet channel connects the pump chamber to a nozzle. A pre-compression valve is arranged between the outlet channel and the nozzle; and a buffer comprising a buffer chamber is connected to the outlet channel. The buffer chamber includes a compressible variator arranged therein for varying the usable volume of the buffer chamber; wherein the nozzle, the buffer and the pump are configured and dimensioned such that the foam is dispensed in a predetermined spray pattern.
