PURPOSE: To allow a gasket to a have a large elastic force through less parts, by providing a space for permitting free deformation of the gasket during the lowering of a stem over the gasket.

CONSTITUTION: In a vlave 110 for spray, when an actuator 128 is pressed to lower the stem 114, the inward end at the radius direction of the gasket 122 fitted in the annular groove 123 in the stem 114 deforms downward axially to open a lateral hole 120, spraying liquid from a container. since the space 131 is formed over this gasket 122, the outward end part at the radius direction of the gasket 122 deforms upward to enter the space 131. When the actuator 128 is released from being pressed, the stem 114 moves up by the elastic force of the gasket 122 up to its initial position. This pressure accumulating type spray valve 110 eliminates the need for a return spring, etc., to reduce the number of parts.
