A valve construction for an aerosol dispenser comprising a valve housing having a chamber and an unyielding transverse wall which defines the bottom of the chamber. An apertured valve seat constitutes the top side of the chamber, there being a valve part having a hollow shank portion extending through the aperture of the valve seat. The valve part comprises an annular valve shoulder engaging the valve seat to close the aperture thereof, and a plurality of sloped, depending, and yieldable integral fingers engageable with and slidable on the bottom transverse wall of the valve housing when the valve part is shifted axially downward with respect thereto. The fingers normally bias the valve part to a raised sealing position wherein the shoulder thereof engages the valve seat and closes off the opening thereof. Depressing movement of the valve part causes flexing of the fingers and unseats the shoulder from the valve seat. The valve part has a side passage communicating with the hollow shank portion to receive liquid under pressure from the valve housing when the part is depressed. Upon removal of the depressing force, the spring fingers bias the valve part to the raised sealing position once again.
