ABSTRACT:
A device for controlling the flow of foam which uses a piston-cylinder arrangement to receive foam at the rapid flow rate of a foam generator until the cylinder is substantially full of foam and then to dispense the foam at a lower flow rate by using the piston to gradually push the foam out of the cylinder.
