<p>A manually-operated liquid spraying device (10) which is of simple construction and easy production. This is so constructed as to intake liquid from a container body (16) into a pressure chamber in which the liquid is applied with pressure and then to spray out finely the pressurized liquid from a nozzle hole (22) by the operation of a trigger (14). A cylinder adapter (26) is fitted within a cylinder bore (25) forming a pressure chamber. A piston member (15) is slidably inserted within the adapter (26). There are formed a liquid intake port (53) communicating with an intake (18) and an exhaust port (48) communicating with a liquid dispenser passage (19) at the end of the adapter (26). A rubber-made valve (50) having a pair of thin tongues (51) is attached at the end of the adapter (26) so as to open only the dispenser port (48) upon pressurizing and to open only the intake port (53) upon pressure reduction. </p> |
