ABSTRACT:
A manually-operable liquid atomizer micropump for spraying liquid contained in a bottle or other receptacle. The subassembly of the pump is formed by a collar which can be fitted in any one of a plurality of bottle covers. The collar is fitted in a cylindrically-shaped body having several diameters and forming an internal skirt and a lower extension for receiving a dip tube. The cylindrically-shaped body houses a helical spring supported by an internal contour of the body and by a step in a valve having a cylindrical lower portion and an upper portion received in the bore of a piston. The spring biases the valve against the bore. The piston and body bound a chamber whose volume can be varied by telescopic movement of the valve in relation to the body. The cylindrical lower portion of the valve cooperates with the cylinder body to control the intake of fluids into the chamber. Liquid in the chamber can be compressed to generate pressure to overcome the bias of the spring, opening the bore of the piston and permitting escape of liquid under pressure through the bore and into ambient atmosphere.
