Abstract

The sprayer air cylinder plunger (41) is coaxial in a cylinder with the air cylinder chamber, connecting the cylinder and exhaust path (34), running along the axial line of the operating member. The air cylinder plunger is water tightly engaged with the air cylinder chamber. The plunger moves up and down within the air cylinder according to the vertical movement of the operating button (17). External air is sucked or exhausted into or from the air cylinder chamber (29) through the nozzle hole (35) and discharge path (34) when the air cylinder chamber becomes broad or narrow in accordance with vertical movement of the plunger.
