A new foam spraying apparatus 1 is described for a liquid container. It comprises a piston and cylinder unit (20; 37) for the air and a piston and cylinder unit (21; 38) for the liquid in which arrangement the piston and cylinder units (20, 37; 21, 38) each are provided with an inlet valve (30; 44) and with an outlet valve (24) and are co-operating being coupled to each other. Furthermore, a mixing chamber (14) for the mixture of air and liquid and a spraying head (2) with a foam delivery opening (9) are provided. The cylinder (20) of the first unit and the piston (21) of the second unit form a unitary body as an intermediate part (5). Furthermore, the piston (37) of the first unit and the cylinder (38) of the second unit also form a unitary body as a base part (4) in such a manner that the intermediate part (5) and the base part (4) mesh and are movable relative to each other.
