Liquid atomizer having a reciprocable pump. The atomizer provides a reliable sealing of the piston rod of the pump with lowered requirements as to the manufacturing tolerances of parts, a simplified manner of venting, and the sealing of the atomizer against leakage when the atomizer is placed in any arbitrary rest position. A sleeve having a smaller inner diameter than the cylinder is mounted on the upper part of the cylinder of the pump and its upper part is in contact with the inner part of a neck of a housing for the atomizer. A free space between the inner wall of the housing and the outer wall of the cylinder of the pump is connected below with the interior of the bottle on which the atomizer is mounted, and the upper part of the free space communicates with the surface of a tube by radial channels passing through the sleeve of the cylinder. The tube slidingly passes through the neck of the housing, is connected on the top with an operating button, and ends below with a sealing cuff piston which covers, when in its upper position, the radial channels and, at the same time, bears by its upper part on the neck of the housing. The tube forms a part of a narrow upper part of a piston rod which reciprocates through the sleeve, whereas the lower broadened part of the piston rod bears the piston of the pump and a one-way valve. |
