ABSTRACT:
An accumulator-type liquid sprayer includes a piston arranged in a cylinder, a piston guide extending through a passage extending therethrough in an axial direction of the piston, so as to be engageable with, and disengageable from the piston, cooperating with the piston and the cylinder to form a space region for sucking and pressurizing a liquid, a check valve for opening a suction port of the cylinder during suction of the liquid, and a hollow stem slidably fitted with an outer side of the piston in a liquid-tight manner and engaging with an end portion of the piston guide. A first resilient member urges the piston guide against the piston for maintaining a closed state of the passage in the piston, and a second resilient member urges the piston against the piston guide for adjusting a spraying pressure of the liquid. A stopper is arranged in the cylinder, for positioning the piston before the content is sprayed to provide increased contact surface pressure so as to maintain the closed state of the passage. The piston has an end portion which can be brought into contact with the stopper, and which is formed with an annular recess extending along an outer peripheral edge of the end portion.
