ABSTRACT:
A fluid is sprayed from a nozzle aperture of a trigger type spraying device under pump pressure generated by the pumping action of an injection pipe member lifted and lowered vertically by an operating mechanism. Said injection pipe member includes a vertical pipe portion, corresponding to a piston, and an oblique pipe portion inclined to said vertical pipe portion. At the tip of said oblique pipe portion, there is provided a discharge valve having an elastically deformable ring member in such a manner that pulling of the trigger portion of a crank lever forces the lower half of said vertical pipe portion, corresponding to the piston, into the cylinder, thereby producing a pumping action. The fluid pressurized in the pump chamber exerts pressure, through means of a fluid passage in the injection pipe member, onto the ring member of the discharge valve in a direction whereby the ring member is flexed so as to open the valve, thereby causing the fluid to be sprayed conically from the nozzle aperture.
