  • the annular projected passage 18b is formed and it is water-tightly in contact with inside of plunger 41 for air cylinder.
  • the pump chamber consisting of the pressure chamber A and pressure chamber B connected through the hole 55 is pressurized as in the case of the first embodiment, and thereby the connecting pipe member 18 moves downward owing to difference of diameters of both cylinders 5, 36, causing the discharge valve 37 to open. Accordingly, the liquid and air are sprayed from the nozzle hole 35.
  • Downward movement of operating member causes the plunger 41 for air cylinder to enter the discharge pipe hole which is also used in common by the air cylinder chamber 29.
  • the discharge valve 37 closes.
  • the suction valve 6 opens and the liquid enters the pump chamber. Simultaneously, the vertical part of discharge path, namely the air cylinder chamber is negatively pressurized and thereby external air is sucked through the nozzle hole.
