Abstract
This unit ensures the dispensing of a liquid in the form of droplets in a virtually continuous manner and a comprises a reservoir (2) containing the liquid to be sprayed, this reservoir communicating with a feeder duct (3) of a precompression pump (4) provided with a delivery duct (5) communication with a spraying nozzle (8). There is a manually-activated pushbutton (7) for actuating the pump and spraying this liquid, this pump comprising a cylindrical body (6) joined to the feeder duct (3), and a piston (10) capable of sliding in a portion with a diameter of the body (6) under the actuation of the pushbutton (7) against a spring (11) along a stroke C. A one-way valve prevents the return of the liquid. A flexible closure (12, 13) releases a dispensing duct (14) in the pump when the pressure obtaining in the body following the actuation of the pushbutton (7) exceeds a specified value.
