A sprayer device (10) with a trigger pump (29) includes a substantially L-shaped body (14) that can be applied to a container for liquids and is provided with a sprayer nozzle (15). A chamber (20) wherein a plunger (33) of the pump slides, an input duct (37) which puts the container into communication with the chamber and an output duct (38) which puts the chamber into communication with the nozzle are formed inside the body. A suction and delivery valve (100) which allows the suction of the liquid from the inside of the chamber and the delivery of the liquid from the chamber to the sprayer nozzle is installed in the chamber of the sprayer body. The stem (32) of the plunger of the pump is operated by a trigger (29) biased by a spring (60).
