The first beverage component is pressurized and is used as the driving fluid for the motor. The second beverage component is pumped by the pump. The first beverage component is exhausted from the motor and delivered along with a second beverage component delivered by the pump. The motor, which may include a piston, requires a predetermined amount of the first beverage component in order to drive the pump to deliver a known volume of the second beverage component.
