Abstract:

[Problem] To provide a pressure accumulation valve that is stable and moves with high sensitivity and yet has a small number of components, and to provide an accumulated-pressure trigger sprayer into which the pressure accumulation valve has been incorporated. [Solution] A pressure accumulation valve (S) used in an accumulated-pressure trigger sprayer (100) for applying pressure to a liquid inside a cylinder by a piston section (11) to spray the liquid from a nozzle section (5a) to the exterior. The pressure accumulation valve (S) comprises: a piston valve section (21); a spring section (22) for pressing the piston valve section (21) against a piston valve seat; and a mounting section (23) for mounting the spring section (22) onto the piston section (11). The piston valve section (21), the spring section (22), and the mounting section (23) are integrally formed.
