Abstract
The disclosure relates to a so-called pressure accumulation type atomizing pump provided with no gravity-actuated check valve and having an upper hollow piston and a lower pistion adapted to be simultaneously moved downward along the inner surface of a valve cylinder, upon a depression of an atomizing push button, the upper and lower piston being adapted to pressurize the liquid accommodated by a housing chamber defined within the valve cylinder between the pistons. The increased pressure of the liquid acts to depress the lower piston to open a check valve leading to a nozzle, so that the pressurized liquid is atomized finely from the nozzle. The lower piston is so arranged as to effectively cooperate with the upper piston in sucking the liquid up during the sucking stroke of the pump and to additionally increase the sucking capacity of the pump.
