ABSTRACT:
An injector dispenser comprises a chamber (1) with two main sections (1a, 1b) of different diameter inside wich moves a primary piston (3) with zones (3a, 3b) of different diameter, with the piston body (3) being traversed by a slide (17), provided moreover with a secondary cylinder (12) and magnetic device of positioning and locking of driven flow that act as a stop on the slide (17), that includes inside it a pair of discs (18, 19) situated at the ends. A pump is achieved with a less complex structure and greater precision in the dispensing of the liquids to be supplied and using less energy.
