Abstract
A dispenser that includes a nozzle that is configured to dispense a fluid. The dispenser also includes a pump in fluid communication with the nozzle and a pulsation dampener in fluid communication with the nozzle. The pulsation dampener has a spring biased movable piston. The dispenser is configured to, when the pump is activated, emit a substantially constant stream of the fluid from the nozzle for at least one second.
